前言在航空工业等尖端部门中,人们愈来愈多地选择粉末冶金作为生产高性能产品的工艺路线。钛的昂贵价格以及高昂的机加工费用刺激了钛粉末冶金技术的发展。与粉末镍基超合金的发展不同,钦粉末冶金还没有达到大规模工业生产的水平。人们可能提出这样两条导致这一结果的理由——市场太小, Foreword In the cutting-edge sectors such as the aviation industry, people are increasingly choosing powder metallurgy as the process route for producing high-performance products. Titanium’s expensive price and high machining costs have stimulated the development of titanium powder metallurgy. Unlike the development of powdered nickel-based superalloys, Chin powder metallurgy has not yet reached the level of large-scale industrial production. One may argue that such two reasons lead to this result - the market is too small,
