Effect of Austenite Dendrite on Shrinkage Porosity
Austenite Branch Crystals on Residual Stress
Crystal structures are the set of atoms that make up the bulk of a material. Austenite, for instance, is a crystal structure that is a type of iron-carbon alloy, with carbon interspersed between iron atoms in the crystal lattice. Austenite branch cryst......

Metallurgic Refining Processes
Metallurgic refining processes are used to purify metals from unwanted elements in ore or other impurities. Refining typically involves separating the desired metal from other metals, minerals, or unwanted elements by heating the ore to a high temperature, often melt......
Metallographic diagram of 60 steel (hot rolled, 810°C normalizing)
The microstructure of SAE 1050 steel (hot rolled and heat treated at 810°C) is studied using optical and scanning electron microscopes. For the microstructure evaluation, a metallurgical sample was prepared and replica was made.
The optical micrograph of the SAE 1050 steel shows a microstructure......
Metallographic structure of 86CrMoV7 cold rolling work roll electroslag ingot
Abstract
The present research study was conducted to investigate the composition and microstructure of the 86CrMoV7 cold-work rolls’ steel billet. To identify the appropriate composition and properties of the material for production of cold work rolls, a thermite process was adopted for refineme......
Metallographic diagram of HT200 steel
The microstructure of HT200 steel is of great importance for its mechanical properties. Microscopic examination of HT200 steel reveals that it is composed of ferrite and pearlite. The presence of pearlite and ferrite is indicative of a hypereutectoid pearlite-ferrite microstructure, also known as ......
Metallographic diagram of QT500-5 steel (350℃ for 1h)
QT500-5 steel is commonly used for automobile and engineering components due to its good mechanical properties and wear resistance. Some parts are made of QT500-5 steel, as they require additional protection against heat or fire. Before using QT500-5 steel, it is important to understand the metall......
S20A (900℃×1 water quenching) metallographic diagram
The microstructure of S20A steel after it has been quenched at 900 degrees Celsius for one hour is composed of pearlite, decahedral spheroidite, Widmanstatten structures, as well as some retained austenite.
The pearlite is the primary phase present in the microstructure, which shows interconnecte......

Metallographic diagram of ZG16Mn (as cast)
Microstructural Characteristics of ZG16Mn Cast Steel
ZG16Mn cast steel is an alloy steel known for its excellent combination of high tensile strength, toughness, and wear resistance. This combination makes it ideal for applications such as components for pressure vessels, pipes and valves, and fo......
Metallographic diagram of 35CrMo (directly quenched after forging)
Introduction
Alloy steels are the steels which comprise the presence of specific alloys for the enhancement of their mechanical properties. The mechanical properties of steels are improved and varied by adding different alloy elements. Alloy steels are mainly divided into low-alloy steels and hig......
