摘要(Abstract)：

利用差示扫描量热仪和拉伸试验研究了400℃×10～120 min和500℃×10～120 min退火态Ti-50.8Ni-0.5V合金的相变行为、拉伸性能和形状记忆行为。结果表明：随退火温度和时间变化，合金的相变类型、R相变温度T_R和热滞ΔT_R、马氏体相变温度T_M和热滞ΔT_M、抗拉强度R_m、伸长率A、应力诱发马氏体相变临界应力σ_M、加载-卸载残余应变ε_R和能耗W_D的变化规律如下：400和500℃退火态Ti-50.8Ni-0.5V合金皆发生B2→R→B19’/B19’→R→B2(B2-母相，CsCl型结构；R-R相，菱方结构；B19’-马氏体相，单斜结构)型相变；T_R~(400℃)>T_R~(500℃),T_M~(500℃)>T_M~(400℃),ΔT_M~(400℃)>ΔT_M~(500℃)≥ΔT_R~(400℃)≈ΔT_R~(500℃)≈4℃;R_m~(400℃)>R_m~(500℃),A~(500℃)>A~(400℃);400℃退火态合金的超弹性(SE)稳定性高于500℃退火态合金。随退火时间延长，T_R~(400℃)、T_R~(500℃)、T_M~(400℃)和T_M~(500℃)升高，ΔT_M~(400℃)和ΔT_M~(500℃)减小，ΔT_R~(400℃)和ΔT_R~(500℃)在3.5～4.6℃之间变化；400℃退火态合金保持SE,500℃退火态合金由SE向SE+SME(形状记忆效应)转变；σ_M~(400℃)和σ_M~(500℃)降低；W_D~(400℃)和W_D~(500℃)增加；ε_R~(500℃)先降后升；ε_R~(400℃)在0.64%～1.36%之间变化。要使Ti-50.8Ni-0.5V合金获得较高的T_R,可对其进行400℃退火；要使该合金获得较高的T_M,可对其进行500℃退火；要使该合金在室温下获得超弹性，可对其进行400℃×10～120 min或500℃×10～60 min退火。
