Obtaining the mechanical response of CuCrZr alloy under coupled electro-magnetic-thermal-mechanical loading is significant for the engineering application of CuCrZr alloy, which is one of the candidate materials for electromagnetic railgun rails. This paper proposes an external-magnetic-field-assisted electromagnetic expanding ring technique, which stably achieves high strain rate loading exceeding 104 s–1 without the significant increase in the induced current and Joule heating temperature rise in the metal sample ring. Based on this technique, a study on the dynamic tensile properties of CuCrZr alloy under coupled electro-magnetic-thermal-mechanical loading was conducted. The stress-strain curves and fracture strain of CuCrZr alloy under conditions of high current density, high strain rate, high temperature rise rate, and strong magnetic field were obtained. The results provide important references for the application of CuCrZr alloy under multi-physics field coupling conditions.

CuCrZr合金作为电磁轨道炮导轨的候选材料之一,获取其在电-磁-热-力多场耦合加载下的力学响应对于CuCrZr合金的工程应用具有重要意义。提出了一种外磁场辅助的电磁膨胀环实验技术,在不显著提升金属样品环中感应电流和焦耳热温升的情况下,稳定实现了104 s−1以上的高应变率加载。基于该技术,开展了电-磁-热-力耦合加载下CuCrZr合金的动态拉伸性能研究,获得了高电流密度、高应变率、高温升率、强磁场环境下CuCrZr合金的应力-应变曲线和断裂应变,研究成果可为CuCrZr合金在多物理场耦合工况下的应用提供重要参考。

CuCrZr合金作为电磁轨道炮导轨的候选材料之一,获取其在电-磁-热-力多场耦合加载下的力学响应对于CuCrZr合金的工程应用具有重要意义。提出了一种外磁场辅助的电磁膨胀环实验技术,在不显著提升金属样品环中感应电流和焦耳热温升的情况下,稳定实现了104 s−1以上的高应变率加载。基于该技术,开展了电-磁-热-力耦合加载下CuCrZr合金的动态拉伸性能研究,获得了高电流密度、高应变率、高温升率、强磁场环境下CuCrZr合金的应力-应变曲线和断裂应变,研究成果可为CuCrZr合金在多物理场耦合工况下的应用提供重要参考。

Obtaining the mechanical response of CuCrZr alloy under coupled electro-magnetic-thermal-mechanical loading is significant for the engineering application of CuCrZr alloy, which is one of the candidate materials for electromagnetic railgun rails. This paper proposes an external-magnetic-field-assisted electromagnetic expanding ring technique, which stably achieves high strain rate loading exceeding 104 s–1 without the significant increase in the induced current and Joule heating temperature rise in the metal sample ring. Based on this technique, a study on the dynamic tensile properties of CuCrZr alloy under coupled electro-magnetic-thermal-mechanical loading was conducted. The stress-strain curves and fracture strain of CuCrZr alloy under conditions of high current density, high strain rate, high temperature rise rate, and strong magnetic field were obtained. The results provide important references for the application of CuCrZr alloy under multi-physics field coupling conditions.

电磁轨道炮是一种依靠电磁能将电枢加速至超高速的新型武器[1]。电枢发射过程中,导轨材料承受脉冲大电流、强磁场、热烧蚀以及电枢姿态变化引起的斜冲击等多物理场耦合极端条件,引发电弧烧蚀、摩擦损伤、刨削侵蚀等极端工况[2–3]。开展导轨材料在多场耦合极端环境下的力学行为研究,可为电磁轨道炮的结构设计和性能优化提供科学依据,从而提高其发射效率、射击精度和服役寿命。
CuCrZr合金具有高导电性、高强度、良好热稳定性及耐腐蚀性等优异的综合性能,是电磁轨道炮轨道的候选材料之一[4–6],其在不同加载条件下的力学性能得到了广泛关注。Wang等[7]对化学成分为Cu0.84Cr0.08Zr和Cu0.7Cr0.13Zr(质量分数)的2种CuCrZr合金样品开展了一维拉伸和压缩实验,结果表明,准静态加载条件下,CuCrZr材料的应力-应变响应表现出典型的拉压对称性。Qian等[8]通过霍普金森压杆实验研究了CuCrZr合金在500~2200 s−1应变率、20~600 ℃温度范围内的动态压缩行为,建立了修正形式的JC本构模型。Huang等[9]对CuCrZr合金进行了高温压缩实验,通过观察热变形后样品的金相组织,发现CuCrZr合金在热变形过程中经历了明显的动态再结晶,构建了CuCrZr高温流动行为本构模型。Zhang等[10]采用等时退火实验,结合硬度测试与材料表征,分析了CuCrZr在1000 ℃以下加热时的组织演变与软化行为。Suzuki等[11]通过断裂韧性和疲劳裂纹扩展实验,获得了CuCrZr在298~573 K的裂纹扩展阻力,发现高温使CuCrZr的延性下降、裂纹扩展速率加快,为评估其在高热负荷下的结构完整性提供了重要数据。然而,对电-磁-热-力多场耦合条件下,尤其是高应变率多场耦合条件下的力学性能研究仍然很少,难以支撑CuCrZr合金材料在电磁发射这种极端条件下的应用研究。
电磁膨胀环技术基于电磁感应原理,利用洛伦兹力在极短时间内驱动环状样品高速膨胀,可在102~103 s−1应变率范围内实现均匀拉伸,是实现电-磁-热-力多场耦合高应变率加载的理想手段之一。自Niordson[12]提出电磁膨胀环技术以来,其在材料动态拉伸行为和动态断裂特性研究方面获得了广泛的应用。Gourdin[13–14]将Rogowski电流探针和任意反射面速度干涉仪(velocity interferometer system for any reflector,VISAR)测速方法引入电磁膨胀环实验,通过测量螺线圈与样品环中的电流以及样品环膨胀速度,对样品环的运动过程进行电磁学分析,获得了样品材料自由膨胀时的应力-应变曲线。Dan等[15]通过在电磁膨胀环装置中引入B.dot磁场探针捕捉7075铝合金的断裂起始时刻,建立了断裂准则和断裂模型以描述样品的断裂特征。Huang等[16]采用电磁膨胀环技术对A5083铝进行动态拉伸实验,发现其断裂应变较准静态实验提高了53%,电子背散射衍射(electron backscatter diffraction,EBSD)分析显示,晶粒细化与高密度小角晶界是电塑性与高应变率协同增强塑性的微观机制。Ma等[17]对比了采用霍普金森拉杆和电磁膨胀环2种实验方法获得的5052-O铝合金的变形行为,发现在2500 s−1拉伸应变率下,电磁膨胀环实验得到的峰值应力低于霍普金森杆实验,其主要原因是电磁膨胀环实验中样品环内的感应电流引起了焦耳热软化。目前,在超过104 s−1的高应变率加载下,电磁膨胀环技术中样品环内的大幅温升容易导致显著的热效应,对解耦分析应变、应变率、温度等不同因素对材料力学性能的影响构成了挑战。
为获取轨道材料在多场耦合极端条件下的力学性能,本研究将开发一种基于外磁场辅助的高应变率加载电磁膨胀环实验技术,在控制样品材料温升基本不变的情况下,实现超过104 s−1的应变率加载。利用新开发的电磁膨胀环实验技术,开展电-磁-热-力多场耦合高应变率加载下CuCrZr合金的动态拉伸性能研究,分析电-磁-热-力多场耦合加载下CuCrZr合金的动态力学响应,以期为CuCrZr合金在电磁轨道发射极端环境下的工程应用提供参考。
电磁膨胀环实验中,金属样品环承受的洛伦兹力由样品环所处位置的感应磁场和样品环内的感应电流共同决定。增加额外的稳态磁场既可提升样品环位置的总磁场强度,又不会引起样品环内感应电流额外增加,从而在样品环温度不显著升高的情况下获得更高的加载速率。以此为指导思想,设计稳态外磁场调控的电磁膨胀环实验装置,如图1所示。将外磁场线圈置于电磁膨胀环驱动线圈和金属样品环外部,外磁场线圈的内径100 mm、外径240 mm、高51.5 mm,线圈截面由4层铜线圈构成,每层5匝,导线截面尺寸为5 mm×4 mm。电磁膨胀环驱动线圈的外径25 mm、高44 mm,由10匝铜导线绕制而成,导线截面尺寸为2 mm×4 mm。
外磁场线圈连接一组总容量为4×830 μF的电容器组,充电4 kV时线圈放电电流和中心磁场曲线如图2(a)所示。电流峰值为19.8 kA,上升沿为744 μs,电流平台宽度(98%~100%电流峰值时的持续时间)为484 μs,线圈内部磁场曲线和放电电流呈线性关系,磁场峰值为3.4 T。膨胀环驱动线圈连接一台容量为40 μF的电容器,充电电压为15 kV时,其电流如图2(b)所示,电流周期为43 μs。通过控制2个线圈的放电时序以及电流方向(初始方向相反),可将驱动线圈的放电过程控制在外磁场保持基本不变的时间窗口,同时保证2个线圈在样品处产生方向一致的磁场,进而使洛伦兹力增大。图2中,Io、B0、U0分别为外部线圈峰值电流、稳态磁场和驱动线圈充电电压。
实验样品环材料为冷轧CuCrZr合金,密度为8.79 g/cm3,导电率为88.3%~89.21%国际退火铜标准(international annealed copper standard,IACS),Cu、Cr和Zr的质量分数分别为 98.84%、1.00%和0.10%。样品环直径为32 mm,横截面尺寸为1 mm×1 mm。采用有外磁场和无外磁场2种方式电磁膨胀加载,获取CuCrZr合金在不同加载条件下的一维拉伸性能,实验布局如图3所示。每发实验使用2个对称布置的光子多普勒干涉测速仪(Doppler interferometric velocimeter,PDV)测速探头测量样品环膨胀速度历史,采用罗氏线圈分别测量驱动线圈与外线圈的放电电流。在样品环正上方放置光电探头,通过测量样品环断裂时刻断口位置的电流打火发光信号来确定断裂时刻,进而确定断裂应变。在样品外围放置石蜡作为软回收装置,实验后取出嵌入石蜡的样品碎片,进行断口形貌观察。
考虑电磁力的影响,金属样品环膨胀过程中的运动方程[18]为
$ {\sigma }_{\theta }=r{f}_{\text{r}}-{r\rho }_{0}\ddot{r} $
式中:σθ为环向应力,$ {\rho }_{0} $为样品环材料密度,r为膨胀环半径,fr为电磁力。
利用实验测量的膨胀环速度vr,计算获得样品环的瞬时半径r、应变$ \varepsilon\mathrm{_p} $和加载应变率$ \dot{\varepsilon}\mathrm{_p} $分别为
$ r=\int\nolimits_{0}^{t}{v}_{\text{r}}\text{d}t+{r}_{0} $
$ {\varepsilon }_{{\mathrm{p}}}=\ln \frac{r}{{r}_{0}} $
$ {\dot{\varepsilon }}_{{\mathrm{p}}}=\frac{{v}_{\text{r}}}{r} $
样品环中感应电流产生的焦耳热以及塑性功耗散会导致样品升温,膨胀环温度Ts为
$ {T}_{{\mathrm{s}}}(t)={T}_{0}+\frac{1}{{c}_{p}\rho }\int\nolimits_{0}^{t}\left[\frac{{R}_{\text{s}}I_{\text{s}}^{2}\left(\tau \right)}{2\text{π}r{A}_{\text{s}}}+{\sigma }_{\theta }\left(\tau \right){\dot{\varepsilon }}_{{\mathrm{p}}}\left(\tau \right)\right]\text{d}\tau $
式中:T0为初始温度,cp为比定压热容,Rs为样品环的电阻,Is为样品环中的感应电流,As为金属样品环的截面积。
按照实验条件进行1∶1几何建模,将罗氏线圈测量的驱动线圈电流以及稳态磁场作为输入条件,开展电-磁-热-力多场耦合有限元仿真。以实验测量的膨胀速度曲线vExp(t)为基准,借鉴铜材料的电导率与温度变化关系,通过调整不同温度区间内电导率的取值,使数值仿真得到的膨胀速度时程曲线vSim(t) 与实测结果的偏差最小化,进而确定数值仿真采用的CuCrZr电导率参数,获取膨胀环承受的洛伦兹力和感应电流。根据式(1)~式(5),计算得到CuCrZr合金膨胀过程中的应变率、应力、应变、温度以及电流密度变化。
共开展了3组对比实验,加载条件以及实验结果见表1,其中:UE、Ii、vP、$ {\dot{\varepsilon }}_{\max } $、tF、$ {\varepsilon }_{\text{F}} $、Ts/$ \varepsilon $、Smax分别为外部线圈充电电压、驱动线圈峰值电流、膨胀环峰值速度、最大应变率、断裂时间、断裂应变、试样温度/应变、回收碎片最大尺寸。驱动线圈充电电压相同时,有/无外磁场条件下实验测量的样品环速度曲线与电磁热力多场耦合仿真计算获得地速度曲线对比如图4所示,数值计算较好的复现了实验结果。根据应力、应变、应变率以及温度计算公式,获得CuCrZr合金膨胀过程中的应变率、温度、应力、应变以及电流密度变化,如图5~图8所示。
实验结果表明,稳态外磁场的引入显著提升了膨胀环的加载应变率,同时降低了样品环的温升。当膨胀环驱动线圈充电10 kV、外部稳态磁场为5.1 T时,膨胀环速度峰值由无外磁场时的117 m/s增大至334 m/s,膨胀环最大应变率由8180 s−1提升至17610 s−1,5%应变对应的温升由217 ℃降低至129 ℃,速度增幅和加载应变率分别增长2.85倍和2.15倍,温升降低了41%。当膨胀环驱动线圈充电20 kV、外部稳态磁场为3.5 T时,膨胀环速度峰值由无外磁场时的388 m/s增大到593 m/s,最大应变率由20480 s−1提升至29470 s−1,5%应变对应的温升由436 ℃降低至308 ℃,速度和加载应变率分别增长1.53倍和1.44倍,温升降低了29%。随着膨胀环驱动线圈充电电压的提升,外磁场的作用逐渐减弱,其原因是外磁场在总磁场中的占比降低。若需在驱动线圈充电20 kV时通过稳态外磁场更加显著地提升加载应变率,外磁场幅值需达到8~10 T,这超出了目前外磁场线圈的能力。
驱动线圈的充电电压相同时,有/无外磁场条件下CuCrZr合金的应力-应变曲线表现为明显的相似性,均呈现先快速下降后变化缓慢的趋势,且有外磁场时材料的流动应力更高。随着驱动线圈充电电压的提升,材料进入屈服后的流动应力表现出随驱动线圈充电电压提升而增大的现象。表2给出了应变为0.01时CuCrZr合金的应力、温度、应变率、电流密度以及磁场强度。随着充电电压的升高,起硬化效应的加载应变率逐渐增大,起软化效应的温升、电流密度和磁感强度也在同步增大,但CuCrZr合金最终表现出明显的应力增强,表明在多场耦合作用下,CuCrZr合金材料的加载应变率变化是影响材料强度的主导因素。
为进一步甄别不同因素对材料力学行为的影响,利用霍普金森压杆测量CuCrZr合金在500~5000 s–1应变率、25~500 ℃温度范围内的应力-应变曲线,联合准静态压缩实验结果,建立修正的JC本构模型,即
$ \sigma=(A+B\varepsilon_{\mathrm{p}}+C\varepsilon_{\mathrm{p}}^2)\left[1+D\ln\left(\frac{\dot{\varepsilon}}{\dot{\varepsilon}_0}\right)^n\right]\left[1-\left(\frac{T-T_0}{T_{\mathrm{m}}-T_0}\right)^m\right] $
式中:参数A=430 MPa,B=336 MPa,C=−528 MPa,D=1.2×10−4,$ \dot{\varepsilon } $=0.001 s–1,n=2.6,T0=25 ℃,Tm=1050 ℃,m=1.8。
基于该本构模型及参数,引入图4和图5中的温度和应变率变化,对电-磁-热-力多场耦合条件下CuCrZr合金动态拉伸过程的应力-应变进行计算,只考虑温度和应变率效应的修正JC本构模型预测结果与电磁膨胀环实验结果的对比如图9所示。图10给出了实验结果和预测结果的差值。预测结果与实验结果的差异表明,电流与磁场可使材料的强度下降超过50%。Okazaki等[19]在77 K低温下的研究表明,104 A/mm2的电流密度可使钛合金材料强度下降126 MPa,而温度仅升高96 K,其原因是大功率高能脉冲电流增强了电子与位错之间的交互作用,进而降低了强度。另一方面,李桂荣等[20]的研究结果表明,磁场与位错的相互作用使得材料强度降低,本实验中样品环的最大电流密度范围为55~110 kA/mm2,样品环位置的最高磁场强度为2.4~7.3 T,电流与磁场引起的电塑性效应导致CuCrZr合金的强度显著降低。
Molotskii等[21]指出,电流引起的磁场变化是脉冲大电流作用下金属材料强度显著下降的主要原因,并给出电流与感应磁场作用下的材料本构关系,即
$ {\sigma }_{j}={\sigma }_{0}\left(1-\frac{{j}^{2}}{{j}^{2}+j_{0}^{2}}\right) $
式中:$ {\sigma }_{j} $为施加电流后的应力,$ {\sigma }_{0} $为未施加电流的应力,j为感应电流密度,参数j0与温度相关。
$ j_{0}^{2}={C}_{1}\exp \left({C}_{2}T\right) $
式中:C1、C2为拟合参数。
本实验中样品区的磁场既包括样品自感应磁场,还包括驱动线圈以及外线圈产生的背景磁场。为了更准确地考虑磁场因素,将式(7)中的修正项改为$ 1-{B}^{2}/\left({B}^{2}+K_{0}^{2}\right) $,同时耦合热力模型的本构方程,则式(7)转变为
$ \sigma=(A+B\varepsilon_{\mathrm{p}}+C\varepsilon_{\mathrm{p}}^2)\left[1+D\ln\left(\frac{\dot{\varepsilon}}{\dot{\varepsilon}_0}\right)^n\right]\left[1-\left(\frac{T-T_0}{T_{\text{m}}-T_0}\right)^m\right]\left(1-\frac{B^2}{B^2+K_0^2}\right) $
其中
$ K_{0}^{2}={C}_{1}\exp \left({C}_{2}T+{C}_{3}{B}_{\text{max}}\right) $
式中:拟合参数C1、C2、C3分别为0.9096、−9.2×10−3、2.096,$ {B}_{\text{max}} $为样品处的磁场峰值。采用式(9)计算获得的应力-应变曲线与实验结果的对比如图11所示,其中:“Exp.”表示实验数据,“TF-Model”表示热力模型预测结果,“EMTF-Model”表示电-磁-热-力模型预测结果。引入电磁耦合修正项后,本构模型的预测精度得到了较好的提升。
根据光电探测器测量信号的突变确定样品环膨胀断裂时刻,继而计算获得CuCrZr合金动态断裂应变。电磁膨胀环实验测量的CuCrZr合金与纯铜[22–23]以及H62黄铜的断裂应变对比如图12所示,CuCrZr合金在最大膨胀速度250~600 m/s(应变率为1.3×104~3.0×104 s–1)范围内的断裂应变稳定在0.4左右,未呈现随膨胀速度增大而增大的趋势,出现了断裂应变的应变率饱和效应[24]。其中,“0 T”代表无外磁场实验,“B0”代表有外磁场实验。图13展示了不同实验样品的回收照片,在相同的20 kV驱动电压下,施加3.5 T外磁场的实验最大回收破片尺寸为4 mm,而无外磁场实验则全部为碎状颗粒。这进一步表明,外磁场调控技术可以实现更高应变率的同时降低样品温度。回收破片的扫描电子显微镜(scanning electron microscope,SEM)断口表征如图14所示,2种加载下的断口均表现出熔化形貌,由此可知,在外磁场加载下,虽然有一定的块状回收,但在断口处,温度仍达到了熔点以上。
基于新发展的外磁场辅助电磁膨胀环实验技术,开展了CuCrZr合金在电-磁-热-力多场耦合条件下的动态力学性能研究,主要结论如下:
(1) 外磁场辅助的电磁膨胀环实验技术在不显著提升金属样品环中感应电流和焦耳热温升的情况下,可稳定实现104 s–1以上的高应变率加载,在相同驱动线圈电压下,加载能力较传统电磁膨胀环提升1倍以上;
(2) 获得了电-磁-热-力多场耦合加载条件下CuCrZr合金的应力-应变曲线,与只考虑温度和应变率效应的修正JC本构模型预测结果进行对比,发现电-磁-热-力多场耦合条件下CuCrZr合金的流动应力比相同参数的热力耦合条件下的流动应力低50%以上,电流和磁场引起的电塑性效应显著降低了材料强度;
(3) 获得了CuCrZr合金材料在1.3×104~3.0×104 s–1应变率(对应最大膨胀速度为250~600 m/s)范围的断裂应变,高应变率条件下CuCrZr合金的断裂应变稳定在0.4左右,未呈现随加载应变率增大的趋势,表明加载应变率达到约1.0×104 s–1以上时,CuCrZr合金的断裂应变出现了应变率饱和效应。
