最近,南朝鲜汉阳大学材料工程系的科研人员,详细研究了镍活化烧结钨的高温性能,测试了其高温硬度、拉伸强度和热膨胀系数,获取了相应的数据。试验所用的试样是以通过镍盐溶液和还原法分别添加了0.2wt.%和0.4wt.%镍的钨粉 Recently, researchers at the Department of Materials Engineering, Hanyang University in South Korea studied the high temperature performance of nickel-activated sintered tungsten in detail and tested its high-temperature hardness, tensile strength and thermal expansion coefficient and obtained the corresponding data. The test sample used was a tungsten powder that was added with 0.2 wt.% And 0.4 wt.% Nickel respectively by nickel salt solution and reduction method
