The use of advanced high strength steels (AHSS) is increasingly preferred in automotive applications due to improved crash energy management and enhanced strength-ductility combinations, resulting in greener and safer vehicles. The weldability of AHSS is generally poorer than conventional steels due to the high alloying contents required to obtain multi-phase microstructure. This course is aimed to discuss the (i) role of alloying elements in stabilizing multi-phase microstructures of AHSS, (ii) effect of weld thermal cycles on the evolution of microstructures and (iii) weldability of AHSS.INTENDED AUDIENCE : Final year bachelors and masters students in Metallurgy, Mechanical, Automobile and Production Engineering. Industrial personnel working in automotive and steel making industries.PREREQUISITES : Final year B.E/B.Tech students or Graduates of Metallurgical/Mechanical/Automobile/Production Engineering,Basic knowledge of steel physical metallurgy and welding processes.INDUSTRY SUPPORT : All automotive manufacturers and their OEMs and Steel plants.
