Abstract

This paper presents a comparison between the computer simulation dissolution model, DICTRA, and an experimental data set from the literature, Baty, Tanzilli and Heckel, 1970. This was undertaken to support research on the modeling of the weld heat-affected zone where grain growth and Zener pinning control materials properties. BTH present quantitative-microscopy data on the dissolution of 5 size classes in their 4.2μ particle sample and 4 size classes in their 0.44μ sample. The DICTRA example of the 3-cell calculation of cementite particles in steel was used as the model to simulate the BTH experiment.
