Metallographic diagram of 12CrlMoV (normalized at 980°C, tempered at 720°C)
CrlMoV is an intermediate in the Cr-Mo series of alloy steel with a tempered martensite. This alloy is most often used in valves, pressure vessels, heat exchangers, and similar items. The CrlMoV alloy is heat treated by preheating to 980°C, followed by a positive temperature hold, and finally coo......

Mechanical Properties and Metallographic Structure of Ductile Iron Single Cast Test Block
ABSTRACT
The purpose of this study was to investigate the mechanical properties and microstructure of a single-cast ductile iron test specimen. The test specimen was obtained from ZZQ Alloy Technology Co., Ltd., which is a leading producer of ductile iron in China. Optical microscopy and nital et......
Fracture toughness
Fracture toughness is an important property of engineering materials. It refers to a materials ability to resist fracture when subjected to dynamic loading. It also provides a measure of how tough a material is. The fracture toughness of a material will vary depending on the type of material, its ......
Fracture Toughness Test
Fracture Toughness Test
Fracture toughness tests measure the amount of energy needed to initiate and propagate a crack in a material. The results obtained from the test are used to determine the material’s resistance to brittle fracture and its ability to reform plastically under an imposed load......
toughness-brittle transition temperature
Introduction
The brittle-ductile transition temperature or what is known as the temperature at which a material will change from brittle to ductile behavior often times plays an important role in determining the properties of a material, especially the strength and toughness. For example, when a ......
