Simulation of Residual Stresses After Quenching of Ring in Compound Materials:Comparison between Heat Treatment Simulation Codes and Test of Material Database Interface

摘要

Quenching of a compound ring was simulated numerically. Two different simulationcodes, DistSIMR and Trast7, were used. The material data were taken from a recently developed database. The database has an interface which can produce input data adjusted to the formats of the two codes. The same original data were used for both simulations although converted to the appropriate formats. The resulting residual stresses were compared. The ring selected for the simulation consists of two materials, an inner part of high speed steel ASP 2060 and an outer part of tool steel K326. The heat treatment simulated was salt bath quenching in 540 degrees C followed by air cooling. Typical values of heat transfer coefficients were used. The results of the simulations showed good agreement between the two models. Since the two models were developed individually this is an indication that the models produce reliable results provided that correct input data are used.
