Following the precipitation process during homogenization by correlative microscopy in aluminium manganese alloy

The correlative microscopy provides an opportunity for combining two visual impressions based on different principles. By this method, the taking of optical microscopic and electron microscopic images become possible about the same experimental area in an appropriate hardware-software environment. In the aluminium-manganese alloys, precipitation form during homogenization which is one of the processes in the rolling technology sequence. The features, morphology and composition of developing precipitation depend on the homogenisation temperature and time, these characteristics change within wide limits. In this study, the precipitates forming during homogenization were examined by correlative method. In 3003 manganese alloy, the appearance of particles at different homogenization temperature and time was followed. The microstructure of sample before and after homogenization was investigated, the phases were identified in the microstructure and the formation processes were followed.
