An Investigation on Shape Memory Effect of FeMnSiCrNiCo Alloy
-
摘要: 针对具有良好耐蚀性的FeMnSiCrNiCo系合金,确定了合理的热加工及固溶处理温度,研究了预变形量、退火温度及记忆训练对合金记忆性能的影响,并分析了微观组织。结果表明,随着预变形量增加,记忆回复率 (ηm)下降,但记忆回复应变量 (εm)有一个最佳值。合金的记忆性能和微观组织随训练退火温度变化而不同,训练退火温度对训练效果起十分关键的作用,母相亚结构是决定合金记忆性能的根本因素。Abstract: The temperature of hot-forming and solution is determined for FeMnSiCrNiCo anti-corrosion alloy. The influence of pre-deformation, annealing temperature and training on shape memory effect is investigated with the analysis of microstructures. The results show that ηm descends and εm reaches a optimum point along with pre-deformation increasing, the shape memory effect(SME) and microstructure of FeMnSiCrNiCo alloy vary with training annealing temperature changing. Annealing temperature plays an important role in training effect and parent matrix sub-structure is an essential factor for the SME of FeMnSiCrNiCo alloy.
