“…In contrast to other steel grades with a different carbon content foils made of C100 are commercially available in a thickness below 100 lm which fulfils the CRC 747 internal definition of micro sheets. This material was also chosen because of the chemical similarity to the bearing steel grade 100Cr6 with its very comprehensive data set [6,7] for thermal as well as transformation simulation. The material properties of the C100 and the 100Cr6 are considered to be sufficiently equal to get the necessary results for the for the design of process experiments.…”

Due to the rising demand for small high-performance products needed in wide sections of applications (for example automotive, micro electronics) the requirements for micro components concerning size scale (miniaturizing), quantity, costs and quality require new micro production processes to be developed. Dealing with the challenges of micro production the Collaborative Research Center 747 (CRC) "Micro Cold Forming" funded by the German Research Foundation was established at the University of Bremen in 2007. One of the elementary process steps during production is the heat treatment. The heat treatment process is responsible for the adjustment of the material properties in order to ensure the ability to form and furthermore to obtain the required mechanical properties. Given the challenges of handling the small and extremely sensitive components with an approximate volume of a cubic millimeter a new heat treatment process has been developed. An integrated 5.5 m high vertical drop-tube furnace enables a short-term austenitisation of steel components during falling. At the bottom of the furnace the quenching takes place by using water or ambient air as quenching medium. By this procedure the hardness of soft-annealed components made of steel quality C100 could be increased from 2196 € 241 HM 0.05/5.0 (revalued 254 € 45 HV 0.005) up to nearly 6700 HM 0.05/5.0 (revalued 1050 HV 0.005).

“…Within the research project SFB 570 "Distortion Engineering" two steel qualities have been in the main focus: the bearing steel 100Cr6 (SAE 52100) and the case hardening steel 20MnCr5 (SAE 5120). The chemical composition of 100Cr6 (used in SFB 570) and material parameters are reported in [13]. For the chemical composition of 20MnCr5 we refer to the conference contribution [1] as well as to [12].…”

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].
