Detecting heat damage and eliminating the susceptibility to sensitization of wrought 5xxx series aluminum-magnesium alloys is of practical importance for the remediation of field structures. Electrical conductivity and hardness testing were employed to provide indirect evidence to assess the microstructural evolution of 5083-H116 alloys after annealing treatment at 150, 200, 250, 300, 350, 400, and 450 °C and sensitization treatment at 175 °C for 168 h. The findings indicate a strong relationship between the hardness, electrical conductivity, and degree of sensitization (DoS). This methodology can be used as a simple guide to quickly determine whether heat damage or sensitization exists.

使用硬度和电导率测试评估5083-H116 Al-Mg合金的热损伤和敏化度
检测热损伤并消除变形的5xxx系列铝镁合金的敏化敏感性对修复现场结构具有实际意义。在150、200、250、300、350、400和450°C进行退火处理并在175°C进行168敏化处理后,采用电导率和硬度测试提供间接证据来评估5083-H116合金的组织演变。 H。这些发现表明硬度,电导率和敏化度(DoS)之间有很强的关系。该方法可以用作快速确定是否存在热损伤或敏化的简单指南。
