Zr、Ti、Hf、Nb对NiAl非晶合金形成的亚规则模型
SUBREGULAR MODEL FOR THE INFLUENCE OF Zr,Ti,Hf AND Nb ON THE NiAl AMORPHOUS FORMATION ABILITY
【摘要】 将亚规则模型应用于Zr、Ti、Hf、Nb对NiAl合金的非晶形成能力的影响研究,发现Zr、Hf的影响要大于Ti、Nb,其原因在于Zr、Hf与Ni、Al的原子尺寸差异要大于Ti、Nb与Ni、Al间的原子尺寸差异。
【Abstract】 A proposed subregular model was used to predict the NiAl amorphous forming ability. The results showed that the transition elements Zr,Ti,Hf and Nb constrain the NiAl amorphous forming ability. The increment of amorphous forming ability was affected by the size difference between Ni,Al in Zr,Ti,Hf and Nb.
