Estimation of applicability of the ukrainian cast piston alloy based on ternary al-me-si system for automobile industry

In this project the applicability of a new generation of heat resistance eutectic alloy based on the ternary al-me-si system for manufacturing automobile parts will be studied. The properties, resistance to fatigue, corrosion and wear will be performed, including final certification.

A novel group of cast aluminium alloys was elaborated by Ukrainian scientists on the basis of fundamental works in phase transformation and physics of strength. The approach for this project is based on using ternary phase diagrams which have quasi-binary sections of eutectic type between the solid solution on an aluminium basis and inter-metallic phases. Due to purposeful alloying, the different mechanisms of strengthening (the composition-, solid solution-, and dispersion-involved ones) are realised. These alloys possess high melting temperatures which are greater than those of other cast alloys. This provides a substantial increase of operational characteristics of cast eutectic aluminium based alloys especially at elevated temperatures. The ideology allows for purposefully changing the properties of cast eutectic aluminium based alloys. It was shown that new aluminium cast alloys on the basis of the Al-Me-Si system offer some preferences over silumins: - Higher heat resistance which is necessary under conditions of piston work for both the bottom and grooves; - Good casting characteristics; - High wear-resistance which is important while working in the zone of piston grooves, gudgeon pin boss, and piston skirt; - Lessening of piston weight due to high magnesium content which is very essential for modern engines. International collaboration is based on using the scientific, technical and financial resources of UKRAINE and SPAIN as well as financing due to participation in European programmes. Ukrainian party: The Frantsevich Institute for Problems of Materials Science, NATIONAL ACADEMY OF SCIENCE OF UKRAINE * Optimises the composition of the content of an eutectic alloy on the basis of an Al-Me-Si ternary system on the main and alloying components in accordance with given demands and determines the level of mechanical tensile properties (tensile strength, yield strength, elongation at room and elevated temperatures) and wear of laboratory ingots. * Establishes the optimal temperature-time relationships of smelting of ingot up to 20 kg, made up of the master alloys from SPAIN. * Delivers ingots with general weight of 300 kg to TARABUSI. Spanish party: TARABUSI (CIE Automotive Group), with subcontracting from TEKNIKER * Develops the requirements specification of the test materials. * Provides requested master alloys. * Manufactures samples from the ingots. * Tests corrosion properties. * Tests friction and wear properties. * Tests mechanical properties (tension tests and fatigue tests at high temperatures). * Tests residual stresses. * Manufactures pistons. * Carries out tribological simulations of piston components. * Carries out engine testing. Project implementation presupposes joint patenting of a new cast alloy and its usage.
