摘　　要：针对医用ZhAO硬组织置换材料的低弹性模量要求,基于粉末冶金制备工艺,探索制备Ti84Mo16合金多孔材料,并以纳米纯钛粉体作为掺杂物,探索纯钛掺杂对Ti84Mo16合金多孔材料力学性能的优化作用。研究发现,在5 h球磨Ti84Mo16粉体中掺杂纳米纯钛粉体,经1200℃烧结工艺后制备的Ti84Mo16合金多孔材料力学性能得到优化,其强度和塑性都得到改善。Aiming at materials targeting for replacing hard tissue, requiring high strength and low elastic modulus, using the powder metallurgy preparation technique, Ti84Mo16 binary composite powders were prepared. Taking nano-pure titanium powder as dopant, the optimized effect of pure titanium doped on porous material mechanics of Ti84Mo16 alloy was explored.The results show that, with increasing nano-size pure Ti content Ti84Mo16 porous alloy, its yield strength and plastic deformation significantly improve.
