UNIDIRECTIONAL SOLIDIFICATION IN HIGHSTRENGTH STEEL CASTINGS.

Abstract

It has been shown that unidirectional solidification results in mechanical properties superior to those associated with conventional solidification techniques. There is a marked effect of mass on the mechanical properties of high-strength steel castings solidified in the conventional manner while unidirectional material is not as sensitive to the mass effect. The unidirectional technique has been translated from laboratory experiment to the actual manufacture of a massive production-type casting. There may be a correlation between the mechanical properties of unidirectionally solidified castings and the dendritic parameters of arm spacing or crossarm length. Current work is directed towards making this correlation. (Author)
