采用XRD,SEM及TEM分析研究间隙原子C作用下Ti-46Al-8Nb-xC (x=0,0.7,1.4,2.5,原子分数,%)合金中析出相的形成规律、析出相与基体相的位向关系及其在热处理过程中的演变规律.结果表明,在C含量为1.4%和2.5%的合金中有长条状Ti2AlC析出,该析出相在铸锭制备的过程中形成,在时效热处理中尺寸、数量和分布均无明显变化,表现出较好的稳定性.不同C含量合金经固溶处理和时效后析出细小针状的Ti3AlC,该析出相从γ相中析出,并与γ相存在位向关系:{100}Ti3AlC∥{100}γ,<001>Ti3AlC∥<001>γ.延长时效时间,Ti3AlC尺寸略有增大,数量变化不明显;升高时效温度,Ti3AlC的尺寸和数量均有显著增加.
