High Temperature Alloys an overview ScienceDirect Topics

High temperature alloys or superalloys are another challenge. They contain chromium for oxidation resistance and elements like aluminum, vanadium, tantalum, niobium, titanium, zirconium, hafnium, and other elements added as gamma prime formers, which strengthen the matrix of the materials by the precipitation of the gamma prime intermetallic compounds that are stable at high temperatures.

High temperature ium alloys AMT Advanced

High temperature ium alloys. Maximum service temperature of ium alloys is mostly limited by the creep and oxidation resistance. Today’s ium alloys are specified for a maximum service temperature of 600°C. However they are used typically for temperatures around 540°C because the parts have a service time of several thousand hours.

Materials Properties Database Text rev1

In term of matrix crystal structure, high temperature alloys can also be classified into BCC ferritic and FCC austenitic formers, as shown schematically in Figure 1. Ni , Fe , Co base superalloys and austenitic stainless steels are FCC formers; ferritic stainless steels as well as Cr base alloys are BCC formers.
