Preparation of Tungsten-Molybdenum-Aluminum Alloy Powder

The invention discloses a tungsten-molybdenum-aluminum alloy powder, which was expressed as W [1-x-y] Al [x] Mo ↓ [y], where: x = 0.01-0.86, y = 0.01 -0.98. Steps are as follows:

1) Tungsten powder, molybdenum powder, aluminum powder and three metal powder or tungsten and molybdenum alloy powder and aluminum powder as raw material, adding mill pot, ball feed ratio of 25:1-50:1, sealed under argon, synthesis time 30-160 hours to obtain aluminum, molybdenum, tungsten alloy powder; zhibei

2) Tungsten powder, molybdenum powder and an aluminum alloy as raw material, a ball mill jar, the ball feed ratio of 25:1-50:1, sealed under argon, the synthesis time is 30-160 hours, the obtained product was placed in a vacuum carbon tube furnace, 1200-1400 ℃ for 5 to 10 hours to obtain aluminum, molybdenum, tungsten alloy powder.

The present invention can be divided into several aluminum ball mill jar was added.
