Abstract

ABSTRACT High-entropy carbides (HEC) are a class of promising new hard phases for a sustainable improvement of hardmetal properties. In this work, hardmetals of the HEC (Ta,Nb,Ti,V,W)C were studied with two typical binder volume fractions of 16 and 24 vol-% consisting of Co, Ni and FeNi. The sintering behaviour, microstructure, phase composition, magnetic and mechanical properties are discussed and are compared to a conventional WC-Co hardmetal. It was shown that the HEC has a high-phase stability and that dense hardmetals with promising mechanical properties were obtained.

不同粘结剂对高熵碳化物基硬质合金的影响

摘要高熵碳化物（HEC）是一类有前途的新型硬质相，可用于可持续改善硬质合金的性能。在这项工作中，研究了HEC（Ta，Nb，Ti，V，W）C的硬质合金，其两种典型的粘结剂体积分数分别为16和24 由Co、Ni和FeNi组成的体积百分比。讨论了WC-Co硬质合金的烧结行为、微观结构、相组成、磁性和机械性能，并与传统WC-Co硬金属进行了比较。结果表明，HEC具有较高的相稳定性，并获得了具有良好力学性能的致密硬质合金。
