Abstract

Material characterization becomes more and more important for the description of material behavior in numerical modeling. To specify the fractions of strain-hardening due to the change of microstructure from austenite into α’-martensite and work-hardening considering the forming process in metastable austenitic steels, a new approach of material characterization is necessary. Therefore, the influence of different forming temperatures is investigated. The present paper deals with various analyses of the phase transformation in deep drawn parts and their characterization in order to examine the formation process at temperatures below the room temperature. Several (residual-) austenitic steels, e.g. stainless steels and TRIP-steels are investigated. One goal of the investigations is the stress-dependent description of strain-induced martensite formation.
