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), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray computed to...
