“…Cold rolling is usually applied during the processing of austenitic stainless steel, which can be used for strengthening, work-hardening, and grain refinement during annealing. This method impacts microstructure, phase transformation, and mechanical properties [20]. For all these reasons, rolling techniques in metal forming operations have been widely studied to analyze the defects and potential application areas for products and components [21].…”

The 17-4 PH stainless steel is widely used in the aerospace, petrochemical, chemical, food, and general metallurgical industries. The present study was conducted to analyze the mechanical properties of two types of 17-4 PH stainless steel—commercial cold-rolled and direct metal laser sintering (DMLS) manufactured. This study employed linear and nonlinear tensile FEM simulations, combined with various materials characterization techniques such as tensile testing and nanoindentation. Moreover, microstructural analysis was performed using metallographic techniques, optical microscopy, scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS), and X-ray diffraction (XRD). The results on the microstructure for 17-4 PH DMLS stainless steel reveal the layers of melting due to the laser process characterized by complex directional columnar structures parallel to the DMLS build direction. The mechanical properties obtained from the simple tension test decreased by 17% for the elastic modulus, 7.8% for the yield strength, and 7% for the ultimate strength for 17-4 PH DMLS compared with rolled 17-4 PH stainless steel. The FEM simulation using the experimental tension test data revealed that the 17-4 PH DMLS stainless steel experienced a decrease in the yield strength of ~8% and in the ultimate strength of ~11%. A reduction of the yield strength of the material was obtained as the grain size increased.

“…[16,28] The distribution of retained austenite in the microstructure can be altered by the processing history and initial microstructure and it is an important factor in the response of TRIP steels. [29][30][31] Since the TRIP steels are usually processed by high-temperature thermomechanical processing followed by cold rolling and finial TRIP heat treatment, the preceding hot-rolling route [32,33] and cooling from the hot-rolling temperature to the ambient temperature might significantly change the initial microstructure and mechanical properties of steels. [34] Regarding the copper-added TRIP-aided multiphase steels, the effects of thermomechanical processing history on the mechanical properties should be further studied for optimization of mechanical properties.…”

The microstructure and mechanical properties of a low‐alloy Cu‐bearing transformation‐induced plasticity (TRIP) steel and their dependence on the processing history were investigated in the present work. The distributions of the retained austenite and bainite were found to be dependent on the initial cold‐rolled microstructure, which can be tailored by the preceding hot rolling route (unidirectional/cross rolling) and the subsequent cooling rate (furnace/air cooling). Mechanical properties and TRIP effect strongly depended on the initial microstructure, where the air cooled sheet showed remarkable mechanical properties; while the cross rolled sheet showed isotropic properties. The addition of copper resulted in an increase in the amount of the retained austenite, enhancement of strength‐ductility balance, and improvement of the hardening behavior of TRIP‐assisted high‐performance steel.This article is protected by copyright.
