据美国金属商情日报报道,美国核金属有限公司巳经研究出一种方法,生产几乎没有钨夹杂的钛合金粉末。据说这种方法是为满足飞机部件对“干净”钛合金粉末需要量的增加而研究出来的。据认为,飞机骨架和飞机发动机用的钛部件中的钨夹杂是低周疲劳裂纹产生的主要原因。该公司的制粉新工艺加上改进的粉末处理方法,使钨的沾污减
According to the U.S. Metal Business Daily, the United States Nuclear Metal Co., Ltd. has developed a method to produce titanium alloy powder with virtually no tungsten inclusions. This method is said to have been developed to meet the increased requirements of aircraft parts for “clean” titanium alloy powders. It is believed that tungsten inclusions in the titanium skeleton of aircraft aircraft and aircraft engines are the main causes of low-cycle fatigue cracking. The company’s new pulping technology, coupled with an improved powder handling method, reduces tungsten contamination
