Abstract
Laser surface remelting offers a promising approach to enhance both the mechanical properties and corrosion resistance of metallic materials by tailoring their surface microstructures. This investigation specifically observed a phase transformation in the Ti-3Zr-2Sn-3Mo-25Nb (TLM) alloy from β to lamellar martensite α“ during the process, resulting in a refined grain structure. Geometrical phase analysis (GPA) revealed heightened internal compressive stress and the accumulation of dislocations along the β/α” interface, contributing to increased strength following laser treatment. Notably, the treated TLM alloy exhibited improved ductility, attributed to the presence of {332} 〈113〉 twinning during dynamic recrystallization. Moreover, the laser-treated surface significantly enhanced corrosion resistance compared to the untreated alloy. This study is anticipated to present an effective approach to prolonging the lifespan of TLM alloy by manipulating its surface microstructure through laser surface remelting.
