Metallographic diagram of 35 steel (high-frequency quenching of rack teeth)
The pearlitic and martensitic structures of 35 steel (tooth part high frequency harden) were observed and discussed via metallorical microscope. The sample had been etched with 4% nital solution, with magnification of 256X. Overall, in the sample, most of the pearlite was observed, along with a sm......

Observations of Polymorphism in Crystals
Crystallography is the study of the structure and behavior of crystals. Crystals are solids whose atoms, molecules or ions are arranged in an ordered pattern that repeats itself in three dimensions. This repeating pattern results from the laws of symmetry,......

20CrMnMo (forged and normalized) Microstructure
20CrMnMo forging and normalizing steel is a kind of composite steel with excellent performance and excellent combination of strength, corrosion resistance, wear resistance, plasticity and impact toughness, which can be used in the manufacture of med......
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......
20 steel (quenched at 930°C) low carbon carbon steel metallographic structure
A Study of Low Carbon Steel and Its Microstructure
Low carbon steels are some of the most widely used steels in the world. They are used in a variety of industries for structural and mechanical applications. The properties of low carbon steels such as strength, formability, and weldability make t......
martensite
Martensite is a very unique form of steel and its properties have made it invaluable in many modern applications. The martensite transformation temperature (Mf) is the temperature below which it is possible for martensite to transform from ferrite or austenite to its more brittle form. This transf......

Major impacts of crystal structures
The crystal structure of a material can have a major impact on its physical, mechanical, and chemical properties. The structure of a material can affect its behaviour in several ways, such as affecting its strength, thermal and electrical conductivity, corrosio......
ferrite, austenite, cementite
Introduction
Metal alloys are ubiquitous around us. The immense variety in their compositions and properties make them suitable for a wide range of applications. The most common alloys consist of iron and trace amounts of other elements, either alone or in combination. Three of the best-known for......
