【摘要】 研究了高能球磨粉烧结93WNiFe合金的力学性能并与机械混料烧结的合金进行了对比,高能球磨粉可以实现在1400℃下固相烧结,密度达到98%以上,经过液相烧结后,高能球磨粉烧结合金的钨颗粒细小,但力学性能没有机械混合粉性能高。对导致球磨粉烧结合金力学性能差的原因进行了分析。更多还原

【Abstract】 The mechanical properties of high energy ball milled and sintered 93WNiFe were studied and compared with that of mechanicall mixed and sintered.Fof the former,after solid state sintering at 1 400 ℃,98 % density can be achieved,and alter state sintering at 1 480 ℃,fine microstructure can be achieved,and tensile strength can reach to 800 MPa,elongation can reach to (5 %.)更多还原
