I recently want to engage in simulation of metal forming processes, but lack experimental data to validate my simulation results. Therefore, I want to consult some papers for comparison with my research. However, articles containing images of deformed material samples are relatively scarce, especially in the field of superalloys. Most papers only provide stress-strain response curves of materials, lacking corresponding photographs. Could you please suggest some papers that include such images of deformed materials, such as samples subjected to cold drawing, cold rolling processes, or specimens with notches showing the overall appearance after tensile deformation?
