Abstract AITranslate

Nano TiC reinforced Ti-matrix composite powder was prepared by mechanical alloying.The phase,morphology,crystal structure and element distribution of the powder were characterized by XRD, SEM,TEM and EDS.The effects of milling speed,ball-to-powder mass ratio and milling time on phase and morphology of the composite powder were investigated.The results show that milling efficiency has no significant difference when milling speed reaches 300 r/min or higher,and ball-to-powder mass ratio reaches 20 :1 or higher.TiC phase in the powder is obvious when milling time reaches 10 h,and nano TiC reinforcement phase is obtained when milling time is extended to 20 h.Under the conditions of 300 r/min milling speed,20 :1 ball-to-powder mass ratio and 20 h milling time,nano TiC reinforced Ti-matrix composite powder can be obtained,and part of the powder is amorphous,where a large number of nano TiC particles are dispersed.
