摘　　要：基于粉末冶金制备工艺,采用碳酸氢氨介质法制备了不同孔隙率Ti84Mo16合金多孔材料。实验以球磨时间作为研究对象,探索球磨时间对Ti84Mo16合金多孔材料力学性能的影响规律。实验结果表明:球磨2 h可以得到强度较高的Ti84Mo16合金多孔材料,而球磨5 h可以得到塑性较高、力学综合性能较好的Ti84Mo16合金多孔材料,同时5 h及以上球磨时间是制备纯β相Ti84Mo16合金多孔材料的合适球磨时间。Based on the preparation technology of powder metallurgy, the Ti84MO6 porous materials with different porosity were prepared using the carbonic acid hydrogen ammonia medium method. Taking the ball milling time as research object, the effect rule of ball milling time on the mechanical properties of the porous materials was explored. The results show that ball milling for 2 h can get high strength Ti84MO6 porous material, ball milling for 5 h can get better comprehensive properties of Ti84MO6 porous materials with higher plastic and good mechanical performance, at the same time, it is the appropriate ball milling time to prepare the pure β phase Ti84MO6 porous materials when ball milling is for more than 5 h.
