Abstract AITranslate

La2O3-doped Mo-12Si-8.5B alloys with different mass fraction of lanthanum oxide were prepared by liquid-liquid doping and plasma activated sintering technology.The phase analysis and observation of microstructures of Mo-Si-B alloys are conducted through XRD and optical microscope.And the mechanical property of alloy is tested.Results show that the Mo-Si-B alloys mainly consist of α-Mo,Mo3Si and Mo5SiB2 three phases,and the microstructure of the doped Mo-Si-B alloy was refined and the compressive strength was improved with the increasing of La oxide doped.
