The phosphorus interaction on the process forming of primary structure of hypereutectic silumins
Journal Title: Archiwum Odlewnictwa - Year 2009, Vol 9, Issue 3
Abstract
In this work the results of investigations concerning the hypereutectic silumins to be used as engine ports have been show. New idea on the interaction mechanism of phosphorus during modification of hypereutectic silumins has been shown. According to this hypothesis the influence of phosphorus is the result of local supercooling caused by evaporation and decompression of phosphorus steam. On the base to propose schematic diagram of the origin of local supercooling as a result of evaporation of phosphorus un microareas with a diversified concentration of silicon of the investigated Al-Si alloys.
