The introduction and growing application of advanced high-strength steels (AHSS) in light vehicle body structure applications poses a significant challenge to organizations involved in the repair of vehicle structures. Recently, the Steel Market Development introduced an expanded portfolio of advanced steel technologies in the FutureSteelVehicle project. These AHSS are typically produced by nontraditional thermal cycles and contain microstructural components, whose mechanical properties can be altered by exposure to elevated temperatures. This temperature sensitivity could alter the mechanical behavior of AHSS after exposure to elevated temperatures during repair welding or flame straightening and could seriously affect the structural performance of AHSS components after repair.
