Some recent developments in modelling of heat-treatment phenomena in steel within the collaborative research centre SFB 570 "Distortion Engineering"Einige aktuelle Entwicklungen in der Modellierung von Phänomenen der Wärmebehandlung beim Stahl im Sonderforschungsbereich SFB 570 "Distortion Engineering"It is the aim to present some developments in modelling of distortion-related phenomena during heat treatment of steel in the context of the Collaborative Research Centre SFB 570 "Distortion Engineering" at the Bremen University, Germany. Taking this into account, a survey will be given and some results will be exemplarily presented. This work is the first contribution to the session "Modelling of material behaviour within the CRC Distortion Engineering" of the 3 Bökenheide et al. 2011 [2] deal in detail with the steel qualities 100Cr6 (SAE 52100) and 20MnCr5 (SAE 5120), respectively. Here, more general aspects of the subsequent phenomena are in the focus: Phase transformations (PT) and transformation-induced plasticity (TRIP) during quenching and heating, plastic behaviour of (supercooled) austenite as well as creep during heating and austenitising. The following items will be considered in particular: Experiments and processing strategies for experimental data, model approaches and results for single phenomena of material behaviour. Many assertions have a general character not linked to special steel sorts. We will also address open questions and possible perspectives. IntroductionIt is the aim to present the development of modelling of steel phenomena which are relevant to distortion of work-pieces during heat treatment in the context of the Collaborative Research Centre SFB 570 "Distortion Engineering" at the University of Bremen. The main concept of this long-time research project (started in 2001) is a system-oriented view on distortion. For a comprehensive explanation we refer to [3].
