【摘要】 用W粉和Ti粉作原料,采用惰性气体热压法制备W/Ti合金靶材。研究了靶材致密性、富Ti的β相含量、微观结构均匀性与工艺条件的关系。结果表明,控制温度在1250~1450℃之间,压力在20 MPa左右,保温时间在30 min左右可制备高性能的W/Ti合金靶材。更多还原

【Abstract】 W-Ti targets were fabricated by inert gas hot press method.The target characteristics including relative density,microstructure,content of Ti rich β phase were introduced.The relationship between target characteristic and technical conditions was researched.The results show that under the condition of temperature range of 1250～1450 ℃,hot press about 20 MPa and heat preservation time about 30 min,good quality target can be fabricated.更多还原
