This study aims to investigate the influence of Mg addition on the microstructure and properties of C19400 alloy, providing a potential approach for performance enhancement. To this end, C19400 alloys with varying Mg contents were fabricated under identical processing conditions, and then the alloys with different Mg contents were processed by thermomechanical treatment. Microstructure, mechanical properties, electrical conductivity, softening temperature, and bending performance of the alloys in different processing states were examined. Results revealed that Mg addition suppressed the precipitation of secondary phase, leading to a finer and more homogeneous dispersion. Under the same deformation and heat treatment conditions, tensile strength and hardness of the alloys increased with Mg content. Moreover, Mg-containing C19400 alloys exhibited superior high-temperature softening resistance, with the softening temperature reaching 490 ℃. Bending performance of Mg-containing C19400 alloys was significantly improved compared with the Mg-free alloys with the same thickness.

本文旨在研究Mg元素对C19400合金显微组织性能与力学性能的影响，为其性能改善提供依据。为此，采用相同工艺制备了不同Mg含量的C19400合金，接着对不同Mg含量合金进行形变热处理加工，并测试了合金在不同加工状态下的微观组织、力学性能、电导率、软化温度和折弯性能。结果表明：Mg的加入能抑制合金中第二相的析出，使其更加细小弥散； 在相同形变热处理下，合金的抗拉强度和硬度随着Mg含量的增加而增加； 含Mg的C19400合金的抗高温软化性能更佳，其软化温度达到490 ℃； 相同厚度下，含Mg的C19400合金的折弯性能更优。
