To evaluate the properties of die casting and squeeze casting, sets of mechanical, structural and stress properties were selected, namely tensile strength, yield strength, hardness, velocity of longitudinal ultrasound waves for the determination of Emodulus, microporosity (assessed by image analysis), porosity (established radiographically), specific mass, microstructure, macrostructure, blistering,...
The radiographic and the strain-gauge (drill hole) methods were used in evaluating the residual stress fields in Al-alloys. Two simulation software programs (MAGMA, SIMTEC) were used to compare the residual stress values established. Discussed in the paper are the potentials of individual methods, possible errors and the determination of residual stress at the critical points in the wall thickness...
