The effects of Zr content on solidification process of Al-Si-Mg-Mn alloy, and its microstructure and mechanical properties after aging treatment were investigated by means of numerical simulation, microstructure observation and mechanical property testing. The research results reveal that with increasing Zr content, the solidification path of the alloy become significantly different, and grains evolve from initial dendrites to equiaxed grains. After aging treatment at 175 ℃ for 7 h, an addition of Zr can significantly improve the hardness of the alloy. The addition of Zr promotes the precipitation of precipitates at lower aging temperature, which may be attributed to grain refinement of Zr, thus leading to improved diffusion efficiency. The main precipitates of the alloy are β″ phase and Q′ phase during peak aging.

通过模拟计算、组织观察以及力学性能测试，研究了不同Zr含量对铸造Al-Si-Mg-Mn合金凝固过程、时效组织及力学性能的影响。结果表明，随着Zr含量增加，合金凝固路径存在显著差异，晶粒由初期树枝晶逐步演变为等轴晶；175 ℃时效7 h条件下，Zr的加入显著提高合金硬度。Zr的加入促使析出相在更低时效温度析出，这可能是Zr细化了晶粒从而提高了扩散效率。峰值时效时合金主要析出相为β″相和Q′相。

摘要
收起

通过模拟计算、组织观察以及力学性能测试，研究了不同Zr含量对铸造Al-Si-Mg-Mn合金凝固过程、时效组织及力学性能的影响。结果表明，随着Zr含量增加，合金凝固路径存在显著差异，晶粒由初期树枝晶逐步演变为等轴晶；175 ℃时效7 h条件下，Zr的加入显著提高合金硬度。Zr的加入促使析出相在更低时效温度析出，这可能是Zr细化了晶粒从而提高了扩散效率。峰值时效时合金主要析出相为β″相和Q′相。

The effects of Zr content on solidification process of Al-Si-Mg-Mn alloy, and its microstructure and mechanical properties after aging treatment were investigated by means of numerical simulation, microstructure observation and mechanical property testing. The research results reveal that with increasing Zr content, the solidification path of the alloy become significantly different, and grains evolve from initial dendrites to equiaxed grains. After aging treatment at 175 ℃ for 7 h, an addition of Zr can significantly improve the hardness of the alloy. The addition of Zr promotes the precipitation of precipitates at lower aging temperature, which may be attributed to grain refinement of Zr, thus leading to improved diffusion efficiency. The main precipitates of the alloy are β″ phase and Q′ phase during peak aging.

近年来，我国汽车工业、航空航天、国防军工等产业飞速发展，但随之而来的能源紧缺和环境问题日渐凸显[1-3]。研发低密度、低成本、高强度的高性能铸造铝合金成为一项紧迫任务，旨在实现产品轻量化，减少能源消耗，降低环境污染，为相关产业的可持续发展提供有力支持。
Al-Si系铸造铝合金因其轻质、高比强度、优异的延展性和铸造性能等，在汽车工业、船舶制造和航空航天等领域具有广泛应用前景[4-6]，如采用Al-10Si-0.5Mg-0.5Mn（牌号Silafont36）合金制造重型卡车保险杠用脚踏板，相较于传统钢制件，质量减轻了33%[1]。
提高铸造Al-Si合金性能，主要有以下途径：①改善共晶Si形貌，通过添加Sr、Na或稀土元素Er、Ce等，使共晶Si从粗大的板片状或长针状变为细小状，改善合金性能[4-9]；②引入细化剂如Al-Ti-B、Al-C-B或Al-Zr细化晶粒，实现细晶强化[6-11]；③加入Mg、Cu、Zn等强化元素，并通过热处理实现固溶和析出强化[10-12]。
前人针对铸造Al-Si合金共晶Si变质、晶粒细化、析出相演变等问题进行了大量研究，其中添加过渡族元素（V、Zr、Ti等）的方法备受关注[13-18]，这些元素既能细化晶粒、改善共晶Si，又能促进强化相的析出[16-22]，例如，在A319合金中加入微量Zr不仅能细化晶粒，而且在固溶处理时形成Al3Zr第二相，提高了合金的强度[18-25]。
目前关于Zr对铸造铝合金时效过程的研究仍然较为有限。本文以常用的铸造Silafont36合金为基础，研究了Zr对Al-10Si-0.5Mg-0.5Mn合金组织、性能以及时效析出过程的影响，旨在为优化热处理制度和提升合金力学性能提供理论依据。

实验主要原料：纯Al（99.9%，质量分数，下同）、Mg锭、Cu丝、Al-20Si、Al-10Sr、Al-5Zr中间合金等，配制3种Al-10Si-0.5Mg-0.5Mn-Zr（w（Zr）=0、0.05%和0.25%）合金。先将配制好的Al锭、Al-20Si放入挤压机（自行研制的400T挤压机）侧边的熔炼炉中，调整炉温至780 ℃，待合金全部熔化后充分搅拌并保温1 h以保证成分均匀，然后将Cu丝、纯Mg加入熔液中并搅拌（Mg按5%烧损配制）；氩气通过石墨转子进入熔液中进行除气除渣（转子速度350 r/min，除气10 min）；待炉温降至730 ℃，加入Al-10Sr，确保熔体中Sr含量160～200 g/t，取适量熔液浇注至蘑菇锭模具中并采用光谱仪（SPECTROLAB M12）分析合金成分，结果如表1所示。由表1可知，合金实测成分与名义成分基本一致。成分合格后，进行挤压铸造，挤压圆棒尺寸为Φ30 mm×200 mm，挤压成形工艺参数为：比压160 MPa，挤压速度40 mm/s，保压时间6 s，模具预热温度200 ℃。
从挤压圆棒中心截取高20 mm的圆柱形试样分析铸态及热处理组织。热处理工艺为：采用两步固溶工艺，首先在480 ℃下保温6 h，再升温至530 ℃保温4 h，然后水淬（水温20 ℃），固溶试样在室温下放置24 h后，进行175 ℃不同时间的时效处理，最后空冷。
使用OLYMPUS SZX10型体视显微镜观察合金晶粒尺寸；经过阳极覆膜（3%HBF4溶液，电流200 mA，80 s）后，使用OLYMPUS GX53型倒置金相显微镜观察覆膜组织。在Wilson® VH1102型显微硬度仪上测试不同时效时间合金的硬度，加载载荷为200g，保压时间10 s，每个试样测试5个点取其平均值。采用Phenom XL型台式扫描电镜（SEM）观察合金T6态的组织形貌，并用附带的能谱仪（EDS）对第二相进行成分分析。利用NETZSCH DSC204 f1型差示热量扫描仪测试固溶态试样升温过程中析出相的演变，升温速率均为5 K/min，氩气流量为60 mL/min。利用JEOL-2000F型透射电镜（TEM）观察纳米态析出相，工作电压为200 kV。
2　实验结果与分析
收起
2.1　凝固过程模拟
图1为Scheil模型模拟的合金凝固路径。合金A中先析出α-Al相，随后析出富Fe、Mn相；加入Zr后，合金B和合金C凝固时会先析出Si2Zr相，随后α-Al和（α-Al+Al15Si2Mn4）相析出，紧接着共晶Si才析出。随着温度继续降低，Al9Fe2Si（β-Al5FeSi）和Mg2Si相才相继析出。合金中含有少量的Cu，从模拟组织中可知，最终的组织中不含Mg2Si相。
2.2　组织演变
图2为合金铸态宏观组织和微观组织。由图2可知，随着Zr含量增加，组织由粗大的树枝晶逐步变为等轴晶。相对应的微观组织显示，合金A和B中树枝晶比较粗大，其当量直径约为350 μm；合金C中则呈现大量的花瓣状等轴晶，其当量直径约为100 μm。这说明，Zr含量0.05%（合金B）时，Zr并没有起到显著晶粒细化效果，Zr含量达到0.25%时，晶粒细化效果明显。有研究表明，Zr的添加可以使合金晶粒细化[25-26]，这是由于添加Zr后形成（Al，Si）3Zr相，随着温度下降，发生包晶反应（包晶成分0.09%）（L+Al3Zr→α-Al，660.5 ℃），α-Al在Al3M颗粒周围形核并生长而使晶粒细化[22-26]。合金B虽然添加了Zr，但含量只有0.05%，低于发生包晶反应的成分，因此晶粒细化效果不明显。
2.3　时效硬度变化
图3为合金在175 ℃时效条件下硬度随时效时间的变化曲线。为了方便对比，图3中也标注了铸态硬度。在铸态下，3种合金的硬度非常接近，说明Zr的加入对铸态合金的硬度影响甚微。固溶处理后，合金硬度均上升，并且随着Zr含量增加，硬度逐步提高。合金A在时效时间0～3 h内硬度迅速上升，3～5 h时硬度又有所下降，5 h后硬度又继续上升并在7 h时硬度达到最高值，然后随着时效时间延长，硬度不断下降。合金B硬度随时间的变化规律与合金A基本相似。合金C在时效时间0～7 h内硬度逐步上升，虽然并没有出现合金A、B中硬度下降的现象，但峰值时效硬度依然出现在7 h处，而且在整个时效时间内合金C的硬度比其他两种合金高。峰值时效时，3种合金的硬度分别为140.24HV0.2、143.81HV0.2和153.37HV0.2，相比合金A，合金B和C硬度分别提高了2.5%和9.4%。
汽车用铝合金零部件不但要有一定硬度，而且注重屈服强度和断后延伸率。表2给出了合金在峰值时效（175 ℃×7 h）状态下合金的力学性能。随着Zr含量增加，合金强度不断提高，断后延伸率则先提高后有所下降。Zr的增加一方面有晶粒细化的作用，另一方面可能促进了析出相的析出，这两方面都会提高合金的强度。晶粒细化一方面会提高合金的韧性，但另一方面加入Zr后也会形成富Zr相，这样会割裂基体，不利于提高合金韧性。
2.4　固溶态DSC分析
图4为固溶态合金DSC曲线（升温速度5 K/min）。峰Ⅰ和峰Ⅱ分别对应β-Mg2Si和Q-Al5Cu2Mg8Si6相的析出，峰Ⅲ对应π-Al8FeMg3Si6相的析出[24]。相比整个析出过程，合金C析出温度比合金A下降了近50 ℃；从析出温度分析，合金C比合金A更低。DSC曲线中每个峰的面积区域代表析出相的析出总量[22]，由图可知，随着Zr含量增加，虽然析出相的析出总量变化不大，但析出相的析出速率明显增加。
2.5　时效析出组织演变
图5为合金峰值时效态（175 ℃×7 h）的SEM显微组织。从图5可以观察到Si相、α-Al15（FeMn）3Si2、π-Al8FeMg3Si6以及（Al，Si）3Zr相，但并未观察到Mg2Si或Q-Al5Cu2Mg8Si6相，这是固溶处理时可溶第二相（Mg2Si、Q-Al5Cu2Mg8Si6、θ-Al2Cu）全部回溶至基体的缘故。由于时效析出相都在纳米尺寸范围内，以至在SEM图中观察不到。但从SEM图可知，合金A、B、C的峰值时效态微观组织中的未溶解相主要是富Fe相和（Al，Si）3Zr相。
图6为3种合金峰值时效状态下的TEM形貌图，对比3种合金的析出相形貌及分布可知，无论Zr含量多少，析出相都呈点状或短杆状形貌；但随着Zr含量增加，析出相数量呈增多趋势，特别是C合金，其析出相数量明显比合金A和B多，从析出强化理论可知，其析出强化效果更好，所以该合金硬度更高。由于Zr的加入并未改变合金时效析出相的种类，并且合金C的析出相数量更多，后续选取合金C分析时效过程中析出相的变化情况。
图7为合金C在175 ℃下时效10 min的TEM明场像及相应的衍射花样。此时合金处于欠时效状态，析出相呈椭圆状（白色虚线椭圆区），析出相与基体之间有明显扭曲，同时根据相应的选区衍射花样可知，该析出相并没有明显的晶体点阵结构，因此，该析出相为GP区。
图8为合金C在175 ℃下时效10 min的峰值时效条件下观察到的析出相及相应的衍射花样。由图8（a）～（b）可知，析出相β″-Mg2Si属于单斜结构体系，点阵常数a=1.51 nm，c=0.67 nm，位向关系为（200）析出相//（301）Al，[010]析出相//[010]Al，这与文献中观察到的β″相完全一致[23-24]。在合金C中除了观察到上述单斜结构的β″-Mg2Si相外，还观察到了另一种不同的相，如图8（c）～（d）所示。这种析出相呈多边形（六边形）结构，点阵常数a=1.032 nm，其a轴和b轴的夹角为120°，是典型的密排六方结构。另外此析出相有3个晶面与Al基体平行，即（103）Al、（501）Al和（506）Al。结合文献[15]可知，此析出相是Q′-Al5Cu2Mg8Si6相。
3　结论
收起
1）随着Zr含量增加，Al-10Si-0.5Mg-0.5Mn-Zr合金组织从粗大的树枝晶逐渐演变为等轴晶。Zr含量0.05%时，晶粒细化效果不显著；Zr含量达到0.25%时，晶粒细化效果显著，呈现花瓣状等轴晶结构。
2）175 ℃时效条件下，随着Zr含量增加，合金硬度逐步提高。在峰值时效状态下，随着Zr含量增加，合金强度逐步提高，断后延伸率先增加后下降，这与Zr的晶粒细化作用和富Zr相的形成有关。
3）Zr含量0.25%时，合金晶粒细化效果显著，可能是通过包晶反应形成了（Al，Si）3Zr相，使得晶粒细化；Zr的加入缩短了合金的析出温度范围，提高了析出相的析出速率。在时效过程中，Zr的加入导致β″-Mg2Si相和Q′-Al5Cu2Mg8Si6相的形成，这对硬度的提高起到了关键作用。
