HIP TREATMENT METHOD WITH FUSED SALT MEDIUM TO ALUMINUM ALLOY OR MAGNESIUM ALLOY CASTING, SALT CORE AND HIP AFTERTREATMENT METHOD AND HIP TREATMENT METHOD WITH FUSED SALT MEDIUM

摘要

PROBLEM TO BE SOLVED: To improve a treating efficiency of a fused salt medium HIP treatment by obtaining a salt scarcely developing corrosion under using temperature state to a heat resistant alloy steel-made pressure vessel as a constituting material in a machining apparatus and having stability and safety to a material to be treated.;SOLUTION: In a method for performing the HIP treatment to an aluminum alloy casting or a magnesium alloy casting by using the fused salt as a heat and pressure medium, the fused salt having 190-290°C melting point is used.;COPYRIGHT: (C)2004,JPO
