Abstract

The present paper deals with twinning-induced plasticity (TWIP) steels with the microstructure refined by severe plastic deformation via equal channel angular pressing and explores the mechanical behavior of steel with qualitatively different microstructures formed in the temperature range 400–900°C. Mechanical characteristics of the steel in different structural states are studied in static tensile tests, biaxial and dynamic tests. Structural changes in the material during severe deformation at different temperatures are discussed, and their effect on the mechanical parameters of TWIP steel is considered. High temperatures of equal channel angular pressing allow for more homogeneous recrystallized structures, which ensure the best combination of the yield stress, formability, plasticity, and crack resistance. These findings can be important in developing high-performance steels for the automotive and hydrogen industries.

高温多道次等径角压制孪晶塑性钢的性能

本文研究了经等径角挤压剧烈塑性变形细化组织的孪晶诱导塑性钢（TWIP），并探讨了在400 ~ 900℃温度范围内形成的不同组织的钢的力学行为。通过静拉伸试验、双轴拉伸试验和动态拉伸试验，研究了钢在不同结构状态下的力学特性。讨论了材料在不同温度下剧烈变形时的组织变化，并考虑了这些变化对TWIP钢力学参数的影响。等通道角压的高温允许更均匀的再结晶结构，从而确保屈服应力，成形性，塑性和抗裂性的最佳组合。这些发现对于开发用于汽车和氢工业的高性能钢材具有重要意义。
