“…Models that include nucleation and growth laws are more and more developed. [27] Interesting developments are also performed for diffusion controlled transformations based on thermodynamics, mainly in ternary alloys. [28] For the precipitation in aluminum alloys, such an approach has been developed recently on the basis of the microstructural analysis mentioned above.…”

The quantitative prediction of the consequences of a heat treatment, in terms of microstructure and hardness, residual stresses and distortions, implies a thorough knowledge of the coupled thermal, metallurgical, and mechanical phenomena that occur during the treatment and their modeling. Recent progress made in that field for metallic alloys (steels, aluminum alloys, and titanium alloys) is reviewed through different examples.

“…1,2) The HAZ, especially the coarsened grain heat affected zone (CGHAZ), has different characteristics from the matrix in microstructure and mechanical properties. During the welding process, CGHAZ has a large prior austenite grain size (hereafter referred to as AGS) and a fast cooling rate due to its severe thermal history.…”

A metallurgical model for the phase transformation kinetics in the coarsened grain heat affected zone (CGHAZ) on the basis of the Johnson-Mehl-Avrami equation is proposed. In this model, the effects of the prior austenite grain size on the transformation and the morphological changes of ferrite are considered. Isothermal dilatometer tests were performed to determine the effects of the prior austenite grain size on the austenite decomposition to ferrite and pearlite in plain carbon steel. By comparing the calculated volume fraction with measured data, the reliability of the developed model is discussed.
