| 摘 要： | 用最近几年在结构相互作用模型方面取得了突破的嵌入原子方法(EAM)和等容分子动力学方法研究了Ni-Al系统的马氏体相变.这一模拟提供了马氏体相变转变过程中原子移动时微观过程的细节.突破了由于相变时间很短(大约10-11s),很难从实验中得到信息的局限.

| Abstract: | The Ni-Al system martensitic transformation is studied with the breakthrough of the embedded atom method(EAM) and isovolumic molecular dynamics study done in the models of structure interactive function in recent years.This simulation provides the details of atomic mobile micro-process in the change of martensitic transformation process,which brings breakthrough in the limitations that it is very difficult to achieve information from experiments because of the short time(about 10-11 s) of transformation.As a result the numerical simulation of the real material properties could become possible. |
