FLT3-ITD: technical approach and characterization of cases with double duplications.

An aluminum alloy suitable for high temperature applications, such as heavy duty pistons and other internal combustion applications, having the following composition, by weight percent (wt %):In this alloy the ratio of silicon:magnesium is 10-25, and the ratio of copper:magnesium is 4-15. After an article is cast from this alloy, the article is treated in a solutionizing step which dissolves unwanted precipitates and reduces any segregation present in the original alloy. After this solutionizing step, the article is quenched, and is then aged at an elevated temperature for maximum strength.
