摘要(Abstract)：

通过真空熔炼技术制备了(Ti_(50)Zr_(50))_(89.7)Nb_(10)B_(0.3)(TZNB0.3,at%)合金，对轧制后的合金分别在550、600和650℃进行再结晶退火处理。结果表明：退火后，TZNB0.3合金的相结构主要为β和TiB相，在550℃退火时，仅部分区域发生再结晶，在600和650℃退火时，再结晶过程完成，再结晶区域为大角度晶界，轧制织构和高密度位错被消除，合金的晶粒轻微长大。随着退火温度的升高，合金的强度逐渐降低，伸长率先增加后减小，在600℃退火时，合金的屈服强度为752 MPa,抗拉强度为804 MPa,伸长率为13.3%,弹性模量为65 GPa,表现出良好的综合力学性能。
