Abstract:A new casting process was defined to fabricate small connecting rods generally produced by die casting. An additional pressure was applied by means of cylindrical pins during the alloy solidification to improve local mechanical properties. The pins were inserted in the fixed semi‐mould and moved by high pressure nitrogen. Connecting rods were fabricated at different squeeze pressures, squeeze times and delay time between the end of the filling stage and the beginning of the pin squeezing. Indentation tests were carried out to measure the effect of the squeezing on the mechanical properties of the cast alloy and a significant improvement was measured. A finite element (FE) model was proposed to simulate the cooling stage of the connecting rod with and without the squeeze pressure. The model was able to predict the modification in mechanical property distribution due to the squeeze pressure and to estimate the reduction in cycle time.

- The objective of the International Journal of Computational Materials Science and Surface Engineering is to establish an effective channel of communication between academic and research institutions and persons concerned with industrial research supported by practical application. It also aims at promoting and coordinating developments in the field of computational materials science and computational surface engineering by publishing original scientific papers which describe computer-aided methods of modelling, simulation and prediction for designing new engineering materials and the technological processes of the manufacturing in materials that are used for solving problems posed by materials and surface engineering professionsals, industrial managers and administrators, and technical education personnel.
