医用Ti基合金形成焓的改进Miedema模型计算

Formation Enthalpy of Medical Ti-Based Alloys Calculated

摘要:

采用改进Miedema模型计算医用Ti基合金的形成焓。结果表明，在医用Ti基合金中掺入非过渡金属Al或Sn能显著降低医用Ti合金的形成焓。对于Ti-Zr系合金形成焓，弹性形成焓的贡献较化学形成焓贡献大

Abstract:

The formation enthalpies of medical Ti-based alloy are calculated by a modified Miedema model. The results show that the formation enthalpy is evidently reduced when the non-transition metal Al or Sn is added into the medical Ti-based alloy. The contribution of elastic enthalpy is bigger than that of chemical enthalpy in the Ti-Zr alloy systems
