“…As the effect of adiabatic heat during high-temperature deformation is not so high in a relative sense, this study did not consider adiabatic heat, which is an approach similar to other studies reported in the literature. 25,26 Therefore, it is expected that different deformation processing maps will be obtained for compressive, as compared to tensile modes of deformation.…”

The efficiency factor (η) and the instability factor ([Formula: see text] in deformation processing maps are regarded as the reliable indices of formability during high-temperature deformation. Deformation processing maps are primarily based on strain rate sensitivity ( m) and are usually created by high-temperature compression tests. To analyze the effect of the mode of flow on the deformation processing map, deformation processing maps based on both compressive and tensile flow curves for 304L stainless steel were determined and compared in the current study. As the instantaneous strain rate varies during both the tensile and compression tests when a constant crosshead speed is used, strain rate compensated deformation processing maps have been determined and compared. In addition, the frictional effect of barreling during compression testing on the deformation processing map has been analyzed. Both deformation processing maps based on either compressive or tensile flow curves are estimated to be complementary.

“…Sachdev et. al 5 used an Aga Thermovision 680 scanner to measure the temperature rise during tensile testing in plain carbon steel, dual phase and High Strength Low Alloy Steels (HSLA) and compared the same with predicted values for adiabatic heating conditions. After these initial studies, no detailed studies have been reported on the use of IR imaging for studying tensile deformation.…”

“…Among the AHSS, the dual phase (DP) steel has gained great attention since it achieves high strength with relatively good formability [1]. However, it was observed that the temperature of the DP steel tends to increase evidently during the plastic deformation [2], which would inevitably affects the plastic flow and formability of the materials [3]. This coupled thermal-mechanical behaviour of the DP steel might bring some difficulties in predicting the spring-back.…”

Abstract. In this paper, uniaxial and biaxial tensile tests with cruciform specimens were conducted to investigate the deformation behaviour of dual phase steel sheet with a tensile strength of 590 MPa (DP590) under evaluated warm-forming temperatures • C). Detailed analyses were then carried out to obtain the corresponding experimental yield loci. For the purpose of describing the temperature-dependent yield behaviour of DP590 appropriately, the Yld2000-2d yield function with temperaturedependent exponent was proposed. The identification procedures of the introduced parameters were then proposed based on Levenberg-Marquardt optimization algorithm. Afterwards, the proposed model was implemented into ABAQUS as user subroutine VUMAT with NICE (Next Increment Corrects Error) explicit integration scheme. The numerical simulations of biaxial tensile tests were then conducted to confirm the validity of the proposed model. It could be concluded that the flexibility and accuracy of the proposed model guarantee the applicability in warm-forming applications.
