据英国《金属文摘》1992年第7期(月刊)报道,一种制造高速穿甲材料的工艺获欧共体专利。专利号为:EP0397305。 该工艺的特点是将粉末化的钨和钽按80％W和20％Ta的比例配制,然后混合均匀。均匀混合后的W-Ta粉末被装进一个金属罐内,在高温下抽真空,以除掉金属罐内混合 According to the British “Metal Abstracts” 1992 seventh issue (monthly) reported that a manufacturing process of high-speed armor piercing material by the European patent. Patent number: EP0397305. The process is characterized by pulverized tungsten and tantalum at a ratio of 80% W and 20% Ta, and then mixed well. The uniformly mixed W-Ta powder was charged into a metal can and evacuated at a high temperature to remove the mixed metal can
