摘要(Abstract)：

以元素粉末为原料,采用模压烧结技术制备了Ti-(2-20)Fe合金(Fe分别为2%、5%、10%、15%和20%),探讨了烧结工艺及Fe含量对合金组织和力学性能的影响规律。结果表明,在1100~1300℃烧结温度内可制备出组织成分均匀、高致密度(约为98%)的Ti-Fe合金材料。随Fe元素含量的提高,合金的烧结致密化温度明显降低,制备合金的晶粒尺寸减小,α层片体积含量降低并逐渐细化。当Fe含量为20%时,合金由单一β相晶粒构成。在1150℃烧结制备的Ti-15Fe合金相对具有最优的综合性能,其硬度为43.9 HRC,弹性模量为64.6 GPa,抗压强度为2702 MPa,压缩率为32.7%。
