| 摘 要： | 将Ti27Nb8Zr合金进行固溶时效处理,应用超声水漫聚焦法并结合纵波掠入射方法测量超声波在各个时效样品中的传播速度,基于声波在各向同性、均匀固体介质中的传播规律,推算时效样品的弹性性能指标.结果表明:随时效温度的升高,声速和弹性性能指标逐渐降低,泊松比增大.分析认为:随着时效时间的延长,马氏体逐步分解成形态与含量均不...

| Abstract: | Ti27Nb8Zr was subjected to solid solution treatment and aging treatment.Using ultrasonic water immersion focusing method combining with longitudinal grazing incidence method,ultrasonic wave velocities in aging specimens were measured.Based on the rule of acoustic wave propagating in isotropic homogeneous solid medium,the elastic indices of aging specimens were deduced.The results show that acoustic velocity and elastic indices decrease and Poission raito increases with the increase of aging temperature.It i... |
