2020年11月,东盟10国和中国、日本、韩国、澳大利亚、新西兰共15个亚太国家正式签署了RCEP,并且各缔约方均承诺将尽快完成协定的核准程序,使RCEP尽早正式生效。有关各方正式签署RCEP及其日后生效,标志着东亚区域合作进入了新阶段,但并非东亚区域合作进程的终点。RCEP正式生效后仍然面临着东亚区域合作方向的选择问题。为了全面落实RCEP的相关规定并在此基础上进一步推动东亚区域合作深入发展,必须继续坚持东盟在东亚区域合作中的主导地位。考虑到东亚地区的特殊性,在深化RCEP等制度性区域合作的同时,仍需坚持开放的地区主义原则,积极探索东亚区域合作的新形式;需要积极推动RCEP框架下的经济技术合作,促进区域包容性发展。此外,还应该在东盟主导下深化区域政治安全合作,促进政治安全合作与区域经济合作良性互动。

对7A99铝合金分别进行峰值时效(PA)和回归再时效(RRA)处理,并复合预轧制与回归再时效(RRRA)以平衡其力学性能和耐腐蚀性能。结果表明,PA处理的试样析出物主要是尺寸细小的不稳定η’相,而经RRA和RRRA处理后则出现粗大稳定的η相。PA处理的试样晶界析出物尺寸最小且呈连续分布,而经RRA和RRRA处理后,晶界析出物的尺寸增大、分布不连续,并发生铜富集。RRRA处理的试样硬度和强度均高于RRA处理的试样,甚至接近PA处理的试样。此外,试样经RRA和RRRA处理后,表现出比PA试样更好的抗腐蚀能力。这些结果表明,提出的预轧制和回归再时效方法能够在不大幅削弱强度的情况下提高合金的耐腐蚀性。
