Phase structure analysis of Mo Si Al based insoluble intermetallic compound alloys
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.
