金属超塑成形是七十年代兴起的一种少、无切削新工艺。它能使某些合金在特定条件下进行“任意”变形,而且成形件的精度很高。对于形状比较复杂、用常规锻造工艺难以成形的锻件,可以采用金属超塑成形工艺。不同的合金有不同的超塑条件。自八十年代初期开始,齐齐哈尔车辆工厂会同有关单位对车辆用HMn52-2-5黄铜进行超塑成形工艺的研究。目前在滑阀生产中已成功地采用这项 Metal superplastic forming is the rise of the seventies, a small, no cutting new technology. It allows some alloys to “deform” arbitrarily under certain conditions, and the precision of the formed parts is high. For the more complex shape, with conventional forging process is difficult to forgings, you can use metal superplastic forming process. Different alloys have different superplastic conditions. Since the early 1980s, Qiqihar Vehicle Works, in conjunction with relevant agencies, has conducted research on the superplastic forming process of HMn52-2-5 brass for vehicles. This has been successfully used in slide valve production
