The sintered Al2O3 blocks with some properties similar to Al2O3 inclusions in ingot were investigated, and the fracture behavior of Al2O3 during deformation was analyzed by high-temperature compression experiments in a special hot compression device. Based on the analysis of fracture characteristics of crushed samples, a prediction model of high-temperature crushing strength of Al2O3 was proposed based on the hyperbolic sinusoidal Arrhenius equation, the region map of crushing mode of Al2O3 characterized by Z parameter was constructed, and the crushing mechanism of Al2O3 at different deformation parameters was revealed. The results show that the hot compression process of Al2O3 has a typical brittle fracture, i.e., its crushing strength is positively correlated to the strain rate and it is negatively correlated to the deformation temperature, and it is more sensitive to the deformation temperature. The crushing mode of Al2O3 inclusions gradually changes from transgranular fracture to intergranular fracture when the Z parameter decreases.

以性质近似于钢锭中Al2O3夹杂的高温烧结Al2O3块体为研究对象,采用专门的热压缩装置,通过高温压缩实验研究了Al2O3在变形过程中的破碎行为,结合破碎样品断口特征分析,建立了基于双曲正弦形式Arrhenius方程的Al2O3高温破碎强度预测模型,构建了以Z参数作表征的Al2O3破碎模式区域图,揭示了不同变形参数下Al2O3的破碎机理。结果表明:Al2O3热压缩过程呈现为典型的脆性断裂,其破碎强度与应变速率呈正相关,与变形温度呈负相关,且对变形温度更敏感。随着Z参数的减小,Al2O3夹杂破碎模式逐渐由穿晶断裂转变为沿晶断裂。

以性质近似于钢锭中Al2O3夹杂的高温烧结Al2O3块体为研究对象,采用专门的热压缩装置,通过高温压缩实验研究了Al2O3在变形过程中的破碎行为,结合破碎样品断口特征分析,建立了基于双曲正弦形式Arrhenius方程的Al2O3高温破碎强度预测模型,构建了以Z参数作表征的Al2O3破碎模式区域图,揭示了不同变形参数下Al2O3的破碎机理。结果表明:Al2O3热压缩过程呈现为典型的脆性断裂,其破碎强度与应变速率呈正相关,与变形温度呈负相关,且对变形温度更敏感。随着Z参数的减小,Al2O3夹杂破碎模式逐渐由穿晶断裂转变为沿晶断裂。

The sintered Al2O3 blocks with some properties similar to Al2O3 inclusions in ingot were investigated, and the fracture behavior of Al2O3 during deformation was analyzed by high-temperature compression experiments in a special hot compression device. Based on the analysis of fracture characteristics of crushed samples, a prediction model of high-temperature crushing strength of Al2O3 was proposed based on the hyperbolic sinusoidal Arrhenius equation, the region map of crushing mode of Al2O3 characterized by Z parameter was constructed, and the crushing mechanism of Al2O3 at different deformation parameters was revealed. The results show that the hot compression process of Al2O3 has a typical brittle fracture, i.e., its crushing strength is positively correlated to the strain rate and it is negatively correlated to the deformation temperature, and it is more sensitive to the deformation temperature. The crushing mode of Al2O3 inclusions gradually changes from transgranular fracture to intergranular fracture when the Z parameter decreases.
