摘要

The article presents the influence of cooling time on the structure of metal matrix composites (MMC) castings. The examination covered two types of composites manufactured by mechanical mixing. Composite reinforcement consisted of SiC particles, and the matrix consisted of AlSi9 alloy in the first case and AlSill in the second. Comparison covered samples cooled in sand moulds and gravity dies by presenting their cooling curves and their abrasive resistance.
