电弧熔炼Nb-Ti-Cr-Si基超高温合金的组织和室温力学性能

Microstructure and Ambient Mechanical Properties of Nb-Ti-Cr-Si Based Ultrahigh Temperature Alloy by Consumable Arc Melting

摘要:

采用真空自耗电弧熔炼法制备了Nb-Ti-Cr-Si基超高温合金合金锭，测试了其室温力学性能。结果表明：合金锭各位置处的成分除Cr元素外分布比较均匀，Cr元素从锭边缘到中心部分呈现减少的趋势。合金的显微组织主要由初生Nbss，呈片层状或花瓣状的Nbss/(Nb, X)5Si3共晶组织及细小的

Abstract:

The ingot of Nb-Ti-Cr-Si based ultrahigh temperature alloy was prepared by vacuum consumable arc melting, and the ambient mechanical properties of the alloy were measured. The results show that the chemical components are distributed uniformly at differen
