Metallographic diagram of ZG1Cr18Ni12Mo3Ti (aqua regia glycerol etching)
ZG1Cr18Ni12Mo3Ti (Wangshuiganyou Immersion Etching) Microstructure
Microstructure analysis is essential for accurate evaluation of material properties and understanding of the structure-property relationship. Corrosion-assisted etching is one of the primary techniques employed in microstructure a......
20 steel (annealing treatment) low carbon carbon steel metallographic structure
，
Abstract
The purpose of this study was to analyze the microstructure of low carbon carbon steel 20-steel (annealed) through metallography. Samples of the three different states, namely as delivered, annealed, and polished, were cut from soldering part of C-type steel washer. It was found that t......
38CrMoAl (gas nitriding treatment) metallographic diagram
A study of the microstructure of 38CrMoAl steel after gas nitriding process
The use of nitriding to improve the surface mechanical properties of steel has been known for hundreds of years. 38CrMoAl steels are widely used due to their excellent mechanical properties and are used in high hot streng......
Identification method of non-metallic inclusions in steel
Identification of Non-metallic Inclusions in Steel
Steel is one of the most widely used materials in the world, used in construction, manufacturing, and other industrial processes. Its wide range of uses is due to its impressive strength and durability, as well as its ability to be formed and mol......
Fracture Analysis of Reaction Furnace Tube

Fracture Analysis of Reactor Tube
Reactor tubes, also known as core tube or ferrite tubes, are components of a nuclear reactor designed to circulate nuclear fuels or coolants. Reactor tubes are subject to immense temperature and pressure fluctuations, over time these tubes may crack or fractur......
Metallographic diagram of 16Mn (normalized at 910°C)
Metallography of 16Mn Hot Rolled Steel
Metallography is defined as the study and analysis of the internal structure of a metal or alloy. It involves the use of microscopes and other optical instruments to closely inspect the microstructure of metals and alloys. Metallography-based analysis is use......
Fracture Analysis of 1Cr18Ni9Ti Fatigue Specimen
Fatigue fracture surface analysis of 1Cr18Ni9Ti
Matrix metallography is a method for viewing microstructures of metals and alloys at a high magnification, usually over 500x. It is used to examine reaction between the different elements in a metal’s microstructure and their environment, as well a......
20MnMo Hydrogen-Induced Cracking Fracture and Stress Corrosion Fracture
Hydrogen Induced Cracking (HIC) and Stress Corrosion Cracking (SCC) of 20MnMo Steel
Abstract
Hydrogen induced cracking (HIC) and stress corrosion cracking (SCC) of 20MnMo steel were investigated using optical and scanning electron microscopy (SEM) techniques in order to determine the characteris......
Metallographic diagram of 20 steel (after carburizing and heat preservation at 960°C, cooling to 860°C and quenching)
叙述
Introduction
Carbon Steels are the most common type of steels in modern times. They are used in a variety of applications, from large construction projects to everyday consumer goods. A specific type of this material is the 20 Steel. This steel is composed of three elements: carbon, iron, and......
