Microstructure and Mechanical Properties of Mo-12Si-8.5B Alloy with Ti Sintered at Different Temperatures AITranslate
Abstract AITranslate
Mo-12Si-8.5B and Mo-12Si-8.5B-8Ti alloys were prepared by spark plasma sintering at different sintering temperatures,and their microstructure and mechanical properties at room temperature were compared.The results show that Mo-12Si-8.5B alloy consists of Moss,Mo3Si and Mo5SiB2,while Mo-12Si-8.5B-8Ti alloy consists of(Mo,Ti)ss,(Mo,Ti)3Si and(Mo,Ti)5SiB2,and solid solution of Ti occurs in the three phases.The density,Vickers hardness and bending strength of the two alloys increase rapidly at the sintering temperatures of 1400~1600℃,and that have no significant change at the sintering temperatures of 1600~1700℃.Compared with the Mo-12Si-8.5B alloy,the hardness and bending strength of the Mo-12 Si-8.5 B-8 Ti alloy sintered at 1700℃ increase by 10.2% and 15.1%,respectively.Therefore,the addition of Ti can improve the mechanical properties of Mo-12Si-8.5B alloy at room temperature,which is attributed to the decrease of micropores in Mo-12 Si-8.5B-8Ti alloy and the solution strengthening effect of Ti in(Mo,Ti)ss,(Mo,Ti)3Si and(Mo,Ti)5SiB2.
