材料的制备加工是决定其使用性能的重要因素之一,也是材料科学与工程的重要组成部分。近20年来,以薄板坯连铸连轧(CSP工艺)、喷射沉积、激光成形、半固态加工、复合铸造、等温成形、无模成形等为代表,材料制备加工新技术新工艺的研究开发与应用受到国内外的广泛重视,得到快速发 Preparation of materials Processing is to determine the performance of one of the important factors, but also material science and engineering is an important part. In the recent 20 years, the research and development of the new technology of material preparation and processing, represented by CSP, spray deposition, laser forming, semi-solid processing, compound casting, isothermal forming and moldless forming, Applications are widely valued at home and abroad, get fast hair
