To achieve an ultra-fine grained structure, 2 passes of constrained groove pressing (CGP) were performed on AZ31 Mg alloy sheets at a temperature of 250 °C. To examine the deformation and fracture behavior of the produced alloy sheets, tensile tests conducted at different temperatures ranging from 25 to 200 °C and strain rates varying from 0.001 to 0.1 s−1. The Box-Behnken design was utilized to conduct experiments, and the response surface methodology was employed to represent the output responses in terms of the key parameters. At a strain rate of 0.0505 s−1 and a temperature of 200 °C, the maximum elongation of 23% was observed, whereas, the material exhibited the yield strength of 128 MPa and the ultimate strength of 163 MPa. Ductile fracture morphology was noticed with increasing temperature. The %elongation slightly decreased as a result of the coarsening of grains at 250 °C. A specialized experimental setup incorporating heating systems was utilized to facilitate high-temperature constrained groove pressing (CGP) on materials that are difficult to deform. A systematic investigation was carried out to analyze the microstructure and mechanical properties of AZ31 Mg alloy sheets subjected to CGP. The study aimed to highlight the influence of the number of passes and thermal deformation on these properties.
