New alloy casting method boosts strength and wear resistance by over 100%!
A new alloy was developed for high-temperature applications to resist wear. By using centrifugal casting, researchers controlled the formation of equiaxed grains in the alloy. The size and shape of the grains were influenced by factors like temperature, cooling rate, and mold rotation speed. Limiting the flow temperature to 1,250°C resulted in fully equiaxed grains. The alloy with fully equiaxed grains showed higher tensile strength at room temperature and 500°C compared to a standard commercial alloy, with lower wear rates.
