The paper presents the results investigations carried out in the frame of the Project CT 96-0750 MicroAlu of Inco-Copernicus program. The investigated materials are PM aluminium alloys with high contents of silicon. The aim of this part is a comprehensive characterisation of microstructure features and specific parameters at the example of an AlSi27Ni6 alloy. The experiments on the plastic and viscoplastic behaviour of this alloy (compressive and tensile tests) at different temperatures and strain rates were done to identify the material properties. The evolution of the microstructure of the tested specimens due to temperature rise and deformation process was investigated with optical and electron microscopy as well as with X-ray analysis technique. The alloy was compacted by a PM extrusion process to a preform and then forged to a final product -connecting rod. From the performed experiments the constitutive parameters were identified and the connecting rod forging process has been simulated by means of a general purpose FEM program.
