摘要
针对"硬组织置换"材料的低弹性模量要求,基于粉末冶金法,探索了不同制备工艺对Ti84Mo16合金弹性模量的影响规律。结果表明:当烧结温度高于1150℃时,烧结温度对Ti84Mo16合金弹性模量影响不是太大,但1050℃烧结的Ti84Mo16合金表现出很低的弹性模量;当球磨时间小于5h,球磨时间对Ti84Mo16合金弹性模量影响不是太大,但随球磨时间增加至10h,Ti84Mo16合金弹性模量下降;球磨粉体制备工艺和原子雾化粉体制备工艺对Ti84Mo16合金弹性模量影响差异不大;在合金粉中掺杂纳米纯钛粉体,可近似地看成是一种以Ti84Mo16合金为基的纯钛颗粒增强复合材料,其弹性模量随Ti含量增加而增加,弹性模量近似满足该复合材料的混合定律。
Materials targeting for replacing hard tissue requires lower elastic modulus. By utilizing the powder metallurgy preparation technique, the influence of processing techniques on the elastic modulus of Ti84Mo 16 alloy was researched. The results show that when the sintering temperature is higher than 1150℃, the influence has rather little meaning, but 1150℃dintering temperature gets lower elastic modulus; when ball mill time is lower than 5h, the influence has rather little meaning, but 10h ball mill time gets lower elastic modulus; ball mill powder and atomization powder have basically the same elastic modulus. Ti84Mo16 ball mill powder mixed by nano-size pure Ti can increase the elastic modulus of Ti84Mo16alloy. These results have important values in medical application.
