Material modelling for simulation of heat treatment
Heat treatment is a collection of many processes such as annealing, stress relief, quenching, tempering, and ageing. All the different heat treatment processes consists the following three stages 1) heating of the material, 2) holding the temperature for a time, and 3) cooling, usually to room.How does tempering affect the hardness of the HAZ?The hardness in the HAZ reduces with increasing distance from the fusion boundary, as the peak temperature experienced reduces. The effect of tempering by multiple weld passes, could be considered to be a number of an isothermal postweld heat treatments.See all results for this questionHow does heat treatment increase the hardness of a metal?The most common heat treatment process of all, hardening is used to increase the hardness of a metal. In some cases, only the surface may be hardened. A work piece is hardened by heating it to the specified temperature, then cooling it rapidly by submerging it into a cooling medium. Oil, brine or water may be used.See all results for this question
