متن کاملNumerical Simulation Of Heat Affected Zone Microstructure During Laser Surface Melting
Microstructural changes during laser welding and laser surface treatment has been regarded by many researchers. Most researches have focused on studying the effect of various process parameters on the size and microstructure of the heat affected zone. But some studies show that the initial microstructure of the base metal can also affect the heat affected zone dimensions and final microstructur...
متن کاملInvestigation on Effect of Heat Input on the Microstructure and Mechanical Properties of Hadfield Steel Weld Joints in SMAW Process
In this investigation, the effect of heat input of SMAW process on the microstructure and mechanical properties of Hadfield steel weld joints was investigated. For this purpose, 4 annealed sheets with thickness 2 mm prepared from Hadfield steel and then welding applied by SMAW process with 6.75 and 11.25 kJ/mm heat input values. The evaluation of the microstructures of welding joints was condu...
