THE EFFECT OF HYDROGEN IN END-CHILLED CAST PLATES OF A356 ALUMINUM ALLOY.

Abstract

The report summarizes the results of tests for hydrogen content, mechanical properties, and solidification rates in end-chilled cast plates of A356 aluminum alloy. Drastically chilled regions of castings exhibit lower hydrogen content than under-riser sections. Lower tensile strength and elongation in castings are obtained with higher hydrogen content in either chilled or slowly solidified parts. Yield strength is not severely impaired in directionally fed sections of cast plates from gassed melts even at remote distances from a chill. (Author)
