1995年10月美国开始研究一种新的粉末压制技术。这一研究项目为期3年,3个单位参加研制,研究经费为850万美元,美国国家标准与技术学会为该项目提供部分资金。这一称之为“动态磁力压制”技术,系采用脉冲调制电磁场施加的压力来固结粉末。如果这一工艺能成功地用于工业生产,那将是低成本制造高密度粉末冶金部件的新途径。初步技术指标为,铁基部件的密度达到7.5g/cm~3,性能与锻钢和粉末锻造钢相当,特别适于制造重型汽车的传动部件。因成本显著降低,因此在汽车工业将有巨大的市场。与传统的粉末冶金压制
In 1995 October the United States began to study a new powder pressing technology. The research project for three years, three units to participate in research and development, research funding of 8.5 million US dollars, the National Institute of Standards and Technology for the project to provide part of the funds. This is called “dynamic magnetic repression” technology, the use of pulsed electromagnetic fields to impose pressure to consolidate the powder. If this process can be successfully used in industrial production, it will be a new way to manufacture high-density powder metallurgy parts at low cost. The initial technical indicators, iron-based parts of the density of 7.5g / cm ~ 3, performance and forged steel and powder forged steel quite, particularly suitable for the manufacture of heavy-duty vehicles, transmission components. Due to the significant cost reduction, there will be a huge market in the automotive industry. With traditional powder metallurgy pressing
