Abstract

The use of secondary materials in the modern world is one of the tasks that has a high priority. One of the harmful impurities in aluminium alloys is iron. Iron is included in the composition as an elongated intermetallic that significantly reduces the properties of the material. In this work, the effect of modification and laser processing on the processes of cyclic destruction of piston aluminium alloy AL25 at temperatures of 20 and 300 °C is considered. The effect of modification on the destruction processes of the secondary aluminium alloy is determined. Phases that reduce the fatigue strength of the alloy have been identified. The effect of laser processing of this material is analysed.

Keywords: • aluminium alloy • modification • laser processing • cyclic destruction
