一、前言 许多实验与理论研究证明:添加少量选择性过渡族元素可明显地降低钨的烧结温度,添加钯和镍能得到最好的活化效果。关于钨的活化烧结,国内外已进行了大量研究工作。1953年C.Agte首先报道了添加0.5～2％镍可使钨的烧结温度降到800℃,1959年 First, the foreword Many experiments and theoretical studies have shown that: adding a small amount of selective transition elements can significantly reduce the tungsten sintering temperature, adding palladium and nickel to get the best activation effect. On the activation of tungsten sintering, a large number of studies have been carried out at home and abroad. 1953 C. Agte first reported that adding 0.5 to 2% nickel can make the sintering temperature of tungsten down to 800 ℃, 1959
