| 摘 要： | 对工业LF6铝合金进行固相结合/超塑成形组合工艺的探索性试验获得成功。研究表明,由东北轻合金加工厂供应的热轧板经温轧复合的板材具有一定的超塑性,可进行超塑成形。轧制连接时,变形量越大,结合强度越大。轧制复合后,扩散退火温度对结合强度有显著影响。由于复合板最佳扩散退火温度(480℃)与最佳超塑变形温度(480—510℃)吻合,因此轧制复合板的扩散退火和超塑成形可同时进行。

| Abstract: | An approach to the solid phase bonding/superplastic forming (SPB/SPF)process of commercial aluminium alloy LF6 sheets was made and proved succes-ful. It is shown that the warm-rolled commercial LF6 sheets after warm bond-ing rolling exhibit their superplasticity and availability to SPF. The greater thebonding rolling reduction, the greater the bonding strength, and the influenceof diffusion annealling temperature on bonding strength is significant afterbonding. |
