S20A (normalizing) metallographic diagram
Metallography is an important analytical method for non-destructive evaluation of a material’s microstructure, grain size, and quality. The S20A (positive fire) metallographic sample studied in this study was sectioned from an aluminum alloy with an average grain size of 8 microns.
The S20A meta......

An Investigation of the Martensitic Transformation in AISI 420 Heat Treated Steel
This paper is an investigation of the martensitic transformation in AISI 420 heat treated steel. AISI 420 Steel is a martensitic stainless steel, widely used in the industrial and naval fields due to its excellent t......
38CrMoA1 (ion nitriding) metallographic diagram
The microstructure of 38CrMoA1 (ion nitrided) was analyzed by optical microscopy. The microstructure consists of martensite, carbides, and carbide networks in the matrix. The carbides have an approximate diameter of 0.2 to 0.4 µm, and the majority of them appear to have a plate-like morphology, b......

Microstructure Analysis of AISI4140CrNiMo After Hardening of 800℃
Introduction
AISI4140CrNiMo, also known as low-alloy medium carbon steel, has many excellent properties including high strength, excellent ductility, and good wear resistance, making it one of the most commonly used steels for ma......
Metallographic diagram of 40CrNiMo (SAE4340)
，2500
A microstructural analysis of the SAE4340(AISI 4340), also known as CrNiMo steel, can provide an indication of the mechanical properties of the material including its machinability. This analysis is typically performed via optical and scanning electron microscopy. In this study, the results ......
A brief introduction to the metallographic structure of lower bainite (lower B)
Lower B Field
Lower B field is a type of grain boundary microstructure that can be observed in alloys. It is generated when an alloy solidifies in a directional cooling process and the grains are stretched and parallel or nearly parallel. The lower B field has a linear boundary pattern consistin......

Microstructure Evolution of AISI 4140 during Quenching and Tempering
Quenching and tempering is a method often used to temper steel alloys such as AISI 4140. This process consists of reheating the steel to above its transformation temperature so that a phase transformation can ta......
15CrA (1100℃×20min+500℃×1s water cooling) metallographic diagram
Study of Microstructure in 15CrA After Thermal Treatment
Heat treatment can alter the microstructure of a material and microscopically affect its physical properties. These changes tend to be quantified by the microstructure observations. One of the most common methods of measuring the microstruc......
18Cr2Ni4WA metallographic diagram
Introduction
A micrograph is a photograph taken through a microscope. A metals micrograph is a photo taken through an optical microscope using a polarization changing tool. The 18Cr2Ni4WA macroscopic has a study of ferrite and pearlite phases grains, distribution and size. It can be determined us......
