| 摘 要： | 用示差扫描热分析仪（ＤＳＣ）和光学显微镜研究了时效对Ｔｉ－５１ａｔ％Ｎｉ形状记忆合金组织和相变行为的影响。加热冷却时，该合金发生了Ｂ_２ Ｒ Ｍ转变。给出了Ｒ、Ｍ相变温度、热滞、相变热与时效温度、时效时间的关系。Ｒ相的形态类似于上贝氏体或魏氏组织。析出物的形态呈针状交叉分布。

| Abstract: | Effect of aging on structure and transformation behavior in Ti-51at%Ni shape memory alloy havebeen investigated by differential scanning calorimetry(DSC)and optical microscopy.B_2 R M transformation took place during cooling and heating processes in this alloy.The relationships of R,M transformation temperature,hysteresis,transformation heat and aging temperature,aging time were given out.The morphology of R-phase is resemblance to upper bainite or Widmanstatten ferrite.The pattern of precipitates is cross distributedneedle. |
