Heat Treatment of Metals

چکیده

Ferrous metals include cast iron, steel, and the various steel alloys, The only difference between iron and steel is the carbon content. Cast iron contains more than 2-percent carbon, while steel contains less than 2 percent. An alloy is a substance composed of two or more elements. Therefore, all steels are an alloy of iron and carbon, but the term “alloy steel” normally refers to a steel that also contains one or more other elements. For example, if the main alloying element is tungsten, the steel is a “tungsten steel” or “tungsten alloy.” If there is no alloying material, it is a “carbon steel.”

Microstructure and Mechanical Properties of the Friction Welded Joint between X53CrMnNiN219 and X45CrSi93 Stainless Steel

Dissimilar metals friction welding of austenitic–martensitic stainless steels is commonly used in order to manufacture engine valves in the automobile industry. In this study, X53CrMnNiN219 (austenitic stainless steel) and X45CrSi93 (martensitic stainless steel) valve steel rods were welded by friction welding process. The welded joint was then heat treated at 760 0C for 60 min. Mechanical prop...

The Heat-Treating Processes Step 5: Cryogenics

Cryogenics is the continuation of heat treatment and is the last step that completes the thermal treatment processing of metals. After ferrous steel part/s are heat-treated and tempered, the part’s grain structure can be improved by subjecting the part to a deep cryogenic temperature (–320 °F) soak. The process involves taking the parts down from room temperature to –70 °F to –100 °F using dry ...
