Abstract
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.关键词
