采用液相烧结工艺.研制了GW-7W合金,适合于作电镦模具材料.结果指出该合金具有较高的高温硬度和抗变形能力。通过电镦试验这种合金比W-20Cu合金砧块,使用寿命提高20倍以上。
The liquid-phase sintering process was adopted.The GW-7W alloy was developed, which is suitable for electric upsetting die material.The results show that the alloy has high high temperature hardness and deformation resistance. By electric upsetting test this alloy W-20Cu alloy anvil, the service life of more than 20 times.
