Jominy End-Quench Test for Hardenability of Steel | Metallurgy

Therefore, if cooling rates as a function of position in parts of different diameters are known, it is possible to use Jominy curves to plot hardness profiles in the parts, i.e., two points in two pieces of same steel if cool at the same rate, the microstructure, the resulting hardness will be the same even in different quenching mediums.

Molybdenum | chemical element | Britannica

Metallic molybdenum has been used for such electric and electronic parts as filament supports, anodes, and grids. Rod or wire is used for heating elements in electric furnaces operating up to 1,700 °C (3,092 °F). Coatings of molybdenum adhere firmly to steel, iron, aluminum, and other metals and show excellent resistance to wear.

Superalloys - an overview | ScienceDirect Topics

Superalloys are a group of nickel, iron-nickel and cobalt alloys, which are widely used in aviation, aerospace and energy industrial clusters as key structural materials. Superalloys usually have excellent heat resistant properties and retain their strength, toughness, fatigue, creep and microstructure stability at the working temperature much higher than the other metals and alloys.

Austempering - Wikipedia

Austempering is heat treatment that is applied to ferrous metals, most notably steel and ductile iron steel it produces a bainite microstructure whereas in cast irons it produces a structure of acicular ferrite and high carbon, stabilized austenite known as ausferrite is primarily used to improve mechanical properties or reduce / eliminate distortion.
