摘要
基于同晶型化合物合金化改性的原理,本研究选择与C11b-MoSi2 同晶型的AlCr2 金属间化合物,按照两种化合物相对摩尔比(AlCr2/MoSi2)设计了0%、10%、20%、30%等四个试验组分,对按比例混合的Mo-Si-Al-Cr元素粉末混合物,采用球磨机械活化热压烧结技术制备了Mo-Si-Al-Cr系合金块体试样,利用X-射线衍射仪(XRD)、金相显微镜(OM)和HX-1000TM型显微硬度计分析测试了各个合金试样的物相组成、金相组织及其显微硬度(HV),根据阿基米德排水法原理,测出了本次试验所需合金的密度.
Abstract
Based on the principle of alloying modification of homomorphic compounds,C11b-MoSi2 isomorphous AlCr2Intermetallic compounds,according to the relative molar ratio of the two compounds(AlCr2/MoSi2)Four test components,including 0%,10%,20%and 30%,prepared Mo-Si-Al-Cr powder mixture of Mo-Si-Al-Cr alloy block sample,gold-phase structure and microhardness(HV)by X-ray diffractor(XRD),metallographic microscope(OM)and HX-1000TM M microhardness meter.According to the principle of Archimedes drainage method,The density of the alloy required for this test was measured.
