一、绪言 G.Karioris研究了用导线放电爆炸(以下简称线爆)法制取超细金属粉,同时还在各种介质中用线爆法探讨了化合物的合成。在前次报导中,对用该线爆法制取的钨、钼和铜粉的特性进行了考察。采用线爆熔化喷射法制取的粉末有较大颗粒。这次对由铁系材料于大气中用线爆法 I. INTRODUCTION G. Karioris studied the preparation of ultrafine metal powder by wire discharge explosion (hereinafter referred to as wire explosion), and explored the synthesis of compounds by wire explosion in various media. In the previous report, the characteristics of tungsten, molybdenum and copper powders prepared by the wire explosion method were examined. The use of line explosion melt injection method has larger particles of the powder. This time by the iron-based materials in the atmosphere by wire explosion method
