【摘要】 测定了母相状态的Ｃｕ－Ｚｎ－Ａｌ记忆合金，在恒应力作用下连续加热过程与中温等温过程的变形量．通过对温度一应变特性、时间一应变特性、组织形貌以及ｘ光结构分析，揭示出了应力、温度及升温速度对应力诱发贝氏体相变的影响。更多还原

【Abstract】 Elongation strains have been measured in Cu-Zn-Al SMA parent phase upon sub-sequent and isothermal heating under stress at moderate temperature. By analyzingtemperature versus strain characteristic and time versus strain characteristic, as well asmicrograph and X - ray diffTaction, the effTects of stress, temperature and heating velocity onstress -induced bainitic transformation have been displayed.更多还原
