Characterisation and Modelling of Non‐Isothermal Precipitation in Metallic Systems

During the process of most age hardening metallic alloys, non‐isothermal precipitation plays a key role. The non‐isothermal nature of precipitation processes can be either imposed by constraints of the process route (e.g. precipitation during coiling of NbC in steels, or precipitation in weld heat affected zones), or it can be found as the optimal pathway to the desired properties (e.g. multi‐step heat treatments of aluminium alloys). The presented work addresses both on an experimental and on a modelling point of view some of these effects, both in aluminium alloys (the Al‐Zn‐Mg and Al‐Zr‐Sc systems) and in a Fe‐Cu alloy.
