High toughness tungsten based heavy alloy containing La and Ca. manufacturing thereof |
摘要 |
A tungsten based heavy alloy having a W-Ni-Fe based composition containing traces of lanthanum or calcium, thereby capable of exhibiting high toughness, irrespective of the content of impurities such as phosphorous and sulfur contained therein, the cooling rate after the sintering treatment and the re-heating treatment. The present invention provides a method for making the high toughness tungsten based heavy alloy. The tungsten based heavy alloy of the present invention is useful to manufacture warheads for breaking armor plates, which require high toughness.
