摘要

The mechanical behavior of CuZn37 brass alloy subjected to tensile and Erichsen tests, with a focus on samples annealed at 400 °C, 450 °C, and 500 °C. The research combines experimental test with Finite Element Analysis (FEA) simulation to assess the effects of different annealing temperatures on the alloy mechanical properties and formability. Tensile tests were performed to evaluate changes in tensile strength, yield strength, and elongation with varying annealing conditions. Simultaneously, Erichsen cup tests were conducted to assess the material’s formability and ductility under different temperatures. The experimental results indicated that annealing temperatures significantly influence the mechanical properties of CuZn37. To complement the experimental data, FEA simulations were conducted to model the material behavior under tensile and Erichsen test conditions. The simulations accurately reflected the trends observed experimentally, showing how grain growth and reduced dislocation density with higher annealing temperatures affect both tensile strength and formability. The FEA results provided deeper insights into the stress–strain distribution and deformation mechanisms, validating the experimental findings and offering a predictive tool for material performance.
