摘要

利用先进的材料物理学方法，研究了在氮气环境中通过电弧堆焊形成的高熵高速非等原子钼工具钢层的结构相态。在 300-1400°C 的温度区间内考察了堆焊层的热力学和机械（弹性模量）特性，并给出了相组成图。研究发现，温度升高伴随着 α→γ 多晶体转变，随后碳化物相含量和弹性模量下降。

Structure and Properties of Surfacing Made of High-Entropy High-Speed Steel

Using the methods of advanced material physics, the structural-phase state of a layer of high-entropy high-speed non-equiatomic molybdenum tool steel formed by electric arc surfacing in a nitrogen atmosphere is studied. The thermodynamical and mechanical (elastic moduli) properties of the surfaced layer are examined in a temperature interval of 300–1400°C, and a phase-composition diagram is presented. It is observed that a temperature increase is accompanied by an α→γ polymorphic transformation, followed by a decrease in the content of carbide phases and elastic moduli.
