三、实现规划的途径与措施为了实现上述规划,我们认为他们可能采取两条途径。一是在一般铸锭冶金已取得的成就基础上发展新的合金和新的加工方法,而这方面的大部分工作是集中在Al-Li系合金的研究方面。二是采用融体急冷新工艺生产粉末, Third, to achieve the planning of the ways and means In order to achieve the above plan, we think they may take two ways. The first is the development of new alloys and new processing methods based on the achievements made in the general ingot metallurgy, and most of the work in this area is focused on the research of Al-Li alloys. Second, the use of melt quenching new technology to produce powder,
