Ever since the environmental concerns became a global issue, industries have paid closer attention to lightweight materials that are higher in strength and lower in density. Lightweight materials are apt for high fuel efficiency, but their low formability and high degree of springback have been the obstacles to their widespread use. Consequently, these materials are called hard-to-form materials. In order to increase the formability of hard-to-form materials and to reduce the degree of springback, there has been much research on warm forming process. However, increasing the temperature of the whole die or the material will result in great energy consumption. As a solution to such drawbacks, this research was conducted with local heating method which heats the area where plastic deformation occurs. After the AZ31, Ti Gr2, Ti Gr5 sheet metals were locally heated by NIR local heating devices, V-bending test was carried out in various temperature condition in order to analyze formability and springbacks. The results of the experiment confirmed the applicability of the NIR local heating method.
