Simulation and Experimental Study on Hot Forging Process of SiCp/2A14 Composite
Taking the trackboard as the research object, the hot forging process of SiCp/2A14 composite slug prepared by stirring and casting method was studied by using numerical simulation and experimental research. The effects of slug size, hot forging pressure, hot forging time, and the heat treatment process on the formability and mechanical properties of the product were studied. The results show that the size of the blank of the similar volume has a great influence on the formability of the part. If the thickness is too thick or too thin, it will lead to die filling dissatisfaction; the higher the hot forging pressure, the more times of forging, the better the formability; after solid solution at 500 °C for 6 h, the parts aging for 8 and 12 h can obtain satisfactory mechanical properties, but it is found that as the aging time increases, the tensile strength of the composite increases while the elongation decreases.
