In squeeze casting, the instant contact between the melt and the die results into the formation of ductile castings of coarse structure due to slow rate of cooling.(a) True(b) FalseThe question was asked during an online interview.This interesting question is from Squeeze Casting topic in portion Special Casting Techniques of Casting-Forming-Welding I

Answer»

The correct choice is (b) False

To explain I would say: The COOLING rate of the molten metal is mainly increased during the SOLIDIFICATION stage of the squeeze casting. The instant contact between the melt and the die surface produces a rapid heat transfer condition that MAKES the casting of good harden-ability with FINE grain structure.
