Effect of vacuum on porosity and mechanical properties of high-pressure die-cast pure copper
Pure copper tensile bars were produced by conventional die casting (HPDC) and vacuum-assist die casting (VADC) processes. Porosity and mechanical properties were investigated by using optical microscopy (OM), ...
