Semi-continuous casting and microstructure investigation of the AlSi12 alloy

Abstract

Semi-continuously cast AlSi12 alloy was investigated by our research group at the University of Miskolc in the Institute of Physical Metallurgy, Metalforming and Nanotechnology under laboratory condition. Our goal was to define correlation and tendency between casting parameters and solidified microstructures. The examined alloy is used as filler material, thus cover soldering technology and exchangers are made from it, like car coolers, radiators, air conditioners. During the investigation optical microscope was used for sight of ingot microstructure, secondary dendrite arm spacing was measured in this way and even the amount of primary α-phase.
