With the increased concerns of environmental issues, industries are paying more attention to lightweight metals. Because the high degree of springback is an obstacle to the widespread use of lightweight metals, many investigations have been conducted to reduce springback by increasing temperature. However, increasing the temperature of the whole die or the material is energy inefficient, since generally only a limited area of the material is deformed during sheet metal forming. As a solution to this problem, focused heating that only heats the area where plastic deformation occurs may be an alternative approach. In the current study, V-bending tests were conducted at various temperatures after the AZ31, Ti-GR2 sheets were locally heated using near-infrared (NIR) radiation in order to evaluate the effect of temperature on springback. The results of the experiment confirm that the NIR focused heating reduces the springback of AZ31, Ti-GR2 alloys with increasing temperature.
