Effect of Post-process Heat Treatment on Tensile Properties: Ti6Al4V ELI Alloy Manufactured by Selective Laser Melting

초록

The Ti6Al4V ELI alloy manufactured using Selective Laser Melting (SLM) technology typically exhibits excellent tensile properties due to the rapid solidification during the laser process. However, it may suffer from low ductility and insufficient fatigue strength, which can introduce defects in the final product. This study aimed to investigate the influence of different heat treatment conditions on the mechanical properties of Ti6Al4V ELI alloy. EBSD analysis was conducted to analyze the tensile characteristics and microstructural differences of SLM-produced Ti6Al4V ELI alloy after various heat treatment conditions. The results showed that when the Ti6Al4V ELI alloy was heat-treated at 850°C, it exhibited superior tensile properties and ductility. © 2024 Korean Institute of Electrical Engineers.
