1、掺钼高强度重合金 这是美国新研制成功的一种高强度钨基合金。这种合金的硬度大于HRC44,可用作穿甲弹。从钼-镍以及钼-铁的两元相图（从略）可明显看出:在重合金液相钨烧结温度下,钼的溶解度比较大,钨和钼在整个合金成分范围内完全相互固溶。若将钼添加到典型的90W-7Ni-3Fe重合金系中,就形成一种独特的现象,即钼与固体和基体互溶,其结果是钼均匀地分布在钨晶粒和基体中。
1, Molybdenum-doped high-strength heavy alloy This is a newly developed high-strength tungsten-based alloy in the United States. The hardness of this alloy is greater than HRC44, can be used as a piercing projectile. From the binary phase diagrams of molybdenum-nickel and molybdenum-iron (omitted), it is clear that the solubility of molybdenum is relatively high at the tungsten-sintering temperature of the heavy alloy liquid and tungsten and molybdenum are completely solidified over the entire alloy composition Soluble. Adding molybdenum to a typical 90W-7Ni-3Fe heavy alloy system creates a unique phenomenon where molybdenum is miscible with both the solid and the matrix, with the result that molybdenum is evenly distributed throughout the tungsten grains and matrix.
