Paper Title:
Influence of the Casting Process on the Properties of Al Based Automotive Components
  Abstract

This work concerns the study of the fatigue properties of A319, A 356 and A357 Aluminum alloys, produced by means of permament mould casting, sand casting and loast foam. Smooth plane or cylindrical samples were cut out from supension arms, engine blocks and cylinder heads and then they were subjected to axial fatigue testing at room temperature. Some castings were subjected to LHIP (Liquid Hot Isostatic Pressing) and also the effect of this process has been evaluated regarding the improvement of fatigue properties. Optical microscopy and scanning electron microscopy (SEM) were used to document the elimination of porosity after LHIP and to show the different nucleation sites of fatigue cracks on the fracture surfaces in no-LHIP and LHIP conditions.
