【摘要】 研究了低温长时间和高温短时两种退火工艺对铜/铝/铜轧制复合板的成型性能及界面结合强度的影响,讨论了退火强化现象没有出现的原因。结果表明,退火处理不能提高铜/铝/铜轧制复合板的结合强度,只能改善复合板的成型性能。铜/铝轧制复合板宜采用高温短时退火制度,退火温度选择580~625℃,时间控制在10 m in以内,此工艺得到的铜/铝轧制复合板综合性能最佳。更多还原

【Abstract】 The effect of annealing at low temperatures for long time and at high temperatures for short time on the formability and bonding strength of Cu/Al/Cu rolling clad sheet has been studied and the reason that the annealing strengthening did not appear in this process has also been discussed.The results show that the annealing process cannot increase the bonding strength of the clad sheet,but it can improve the formability.In order to satisfy the formability(bending property),Cu/Al/Cu rolling clad sheet should be annealed at a high temperature for a short time.The optimum comprehensive properties were achieved when the sheet was annealed at 580～625 ℃ for less than 10 min.更多还原
