Part I. The Metallurgy of: “Alloy Selection for Elevated Temperature Application”

Introduction This is a complex subject in part due to the time dependant mechanical behaviour of metals under load at elevated temperature. At room temperature, we understand that a part is failing once it is past it’s yield point – plastic deformation is occurring. The part is completely destroyed once…

Part II. The Metallurgy of: “Alloy Selection for Elevated Temperature Application”

Malabou cast special alloys that allow for castings to be used at elevated temperature’s, in some cases in excess of 1000°C. These heat resistant casting alloys consist of predominantly of combinations of nickel, chromium and iron together with small percentages of other elements. Castings made of these high temperature alloys…
