Austenite Formation and Austenitic Steel
Austenite is a very important constituent of molten steel and is often referred to as the mother of steels. In 1868 the German metallurgical scientist Julius Lother von Franckenstein identified Austenite as being a combination of ferrite and cementite whe......

The Different Types of Alloy Phases
Alloy phases, which are defined as the various mixtures and arrangements of chemical elements, are important components of many engineering alloys. These phases, which are often present in the same alloy, can have a major impact on the strength and other proper......
17-4PH (0Cr17Ni4Cu4Nb) metallographic diagram
1. Introduction
0Cr17Ni4Cu4Nb (17-4PH) is an iron-based precipitation-hardening stainless steel with a nominal composition of 17Cr-4Ni-4Cu-Nb. It has been widely used in industrial applications due to its excellent combination of mechanical properties, corrosion resistance and fabrication charact......
18CrMnTi (1100℃×20min+470℃×3s water cooling) metallographic diagram
Austenitic Structures in 18CrMnTi Steel after Heat Treatment
Developer summary
This project aims to study the structure of 18CrMnTi steel after it has been subjected to a heat treatment at 1100°C to form an austenitic microstructure. The sample was then quenched in water at 470°C for 3 seconds......

Characterization of Microstructure of 20CrMnTi Alloy after Forging and Annealing
20CrMnTi alloy is a kind of steel which is widely used for its excellent properties, such as strength, hardness, corrosion resistance and abrasion resistance. In order to improve the mechanical properties of the allo......
Austenite primary grains in steel
Austenite is a type of steel microstructure produced when steel is austenitized. This occurs when steels are heated to high temperatures, usually around 1394-1562 °C, for sufficient time to change the chemical composition and produce austenite in place of the original components of ferrite and ce......
Austenitic essential grains of steel
Austenite is a non-magnetic and highly ductile phase of iron-carbon alloys. In metallurgy, it is sometimes referred to as gamma iron. Austenite exists at high temperatures and it is the face-centered cubic (fcc) form of iron. At temperatures below 912°C (1674°F), an iron-carbon alloy will form a......

Austenitic Steels
Austenitic steels are the most widely used type of stainless steel. They are characterized by their austenitic microstructure, which has a ferritic base containing high levels of chromium (Cr) and nickel (Ni), as well as other alloying elements like molybdenum (Mo), nitrogen (N)......
supercooled austenite
Austenite is the solid solution phase of iron carbide in iron. A commonly known type of Austenite is cementite, which consists of iron and carbon.
Austenite is an important alloying constituent for many steels. Its presence significantly increases a steels resistance to softening by heat. It is a......
