| 摘 要： | 利用控温拉伸实验,结合微观组织形貌观察和层错能的计算,分析了在-60-600℃温度范围变形时高锰TWIP钢Fe-23Mn-2Al-0.2C力学性能和显微组织的变化规律及变形温度对其变形机制的影响.结果表明,随着变形温度的升高,TWIP钢的强度和延伸率总体上呈现先降低后增加,然后又降低的趋势.在300℃变形时,强度和延伸...

| Abstract: | Twinning-induced plasticity(TWIP) steel can be classified into three types,Fe-Mn -Al-Si,Fe-Mn-C and Fe-Mn-Al-C steels.Owing to their high strength,superior plasticity and good formability,they have potential applications in automobile manufacturing industry as a new generation of steels.In order to reveal the dependence of deformation mechanism on temperature for Fe-23Mn-2Al-0.2C TWIP steel,microstructural observation,stacking fault energy calculation and tensile deformation experiments were performed at a ... |
