Warm-stamping mechanical behavior and microstructural characterization of Al-Si metal sheets using water refrigerated tooling

The use of water refrigerated tooling in a laboratory scale was used to simulate conditions of warm (500°C) stamping of aluminum plates with 0.8 mm in thickness. The work presents load-displacement curves of room temperature and heat treated samples during stamping at 120 and 240 mm/min, effect of the treatment in the anisotropic characteristics of the rolled sheet plate and electron microscopy analysis along with element detection, as this alloy contains small amounts of silicon. The processes resembles a solution treatment and, thus, also an aging treatment at 120°C for 12 h was carried out in order to understand the application possibilities of the manufacturing process in the automotive or aero-space industry.
