Abstract

Effect of microalloying by boron, added by two different methods, on the microstructure and martensitic transformation in as-cast and aged Ni54Fe19Ga27 alloys was studied. The increase of the aging time of the Ni54Fe19Ga27 alloy from 0.5 to 10 h at 823 K leads to the formation of a large volume fraction of the ordered γ′-phase. Microalloying with boron inhibits the precipitation of the γ(γ')-phase and prevents its ordering. The parameters of martensitic transformation are most stable with increasing aging time of a (Ni54Fe19Ga27)99.7B0.3 alloy when boron is added in the form of a NiB alloy.

硼微合金化对时效镍铁镓(B)合金微观结构和热弹性马氏体转变的影响
研究了通过两种不同方法添加硼的微合金化对铸态和时效 Ni54Fe19Ga27 合金的微观结构和马氏体转变的影响。在 823 K 下,将 Ni54Fe19Ga27 合金的时效时间从 0.5 小时增加到 10 小时,会导致有序γ′相形成较大的体积分数。用硼进行微合金化可抑制γ(γ')相的析出并阻止其有序化。当以 NiB 合金的形式添加硼时,(Ni54Fe19Ga27)99.7B0.3 合金的马氏体转变参数随时效时间的增加而变得最稳定。
