Casting structure of metals and alloys
，关于金属及合金的铸造组织。
Casting organization is one of the important basis to realize the casting quality. The purpose of studying the casting structure of metal and alloy is to further understand the performance, reliability, stability and other properties of metal and alloy. It is of great p......
00Cr17Ni14Mo2 (10% ammonium persulfate aqueous solution electrolytic etching) metallographic diagram
The observed microstructure of SUS316L after 10% Ammonium Sulfate (NH4 2SO4) electro-etching showed a banded-type ferrite-characteristic structure, which appear as a subset of ferrite.( Figure2). The ferrite bands were characterized by elongated grains of grains and grain sizes in the range of 2 t......
50B (930℃×1h oil quenching) metallographic diagram
The microhardness, composition and fraction and morphology of the as-quenched cobalt-containing iron-chromium-nickel alloys (930°C × 1h oil-quenched) were studied for the study of microstructure of the alloys. The cobalt-containing iron-chromium-nickel alloys were obtained from the vacuum arc me......
Metallographic diagram of 65Si2MnWA (after hot rolling)
65Si2MnWA (hot rolled) ferrite-pearlite material is characterized by a chemical and microstructural composition that can be used in many applications that require a high strength combination of material properties and weldability. The chemical composition of the grade is 65% Si, 2% Mn, 0.3% Ni, 0.......
Fracture Analysis of 70 Steel (Middle Temperature Tempering After Quenching)
Introduction
1770 steel is an alloy primarily composed of iron and carbon, with a lower content of other alloying elements than either other carbon or low alloy steels. It is also known as shallow hardening steel due to its ability to be hardened or strengthened with a lower level of heat energy......
Metallographic diagram of 9G6W3Mo2V2 and 20CrMo
Metallographic Examination of 20CrMo and 9G6W3Mo2V2 Steels
Metallography is an essential tool for gaining a better understanding of the mechanical and structural behaviour of a metal. As such it is widely used in the study of steels, including the high performance steels 20CrMo and 9G6W3Mo2V2, fo......

Microstructure Analysis of 65Mn2V Steel
Introduction
65Mn2V steel is a low-carbon alloy steel with excellent toughness, strength, ductility and machinability. It is renowned for its wear and fatigue resistance properties, making it particularly suitable for components such as gears and cams that......
Metallographic diagram of CK15 (quenched and tempered after carbonitriding treatment)
Centrifugal Casting
Centrifugal casting, also known as rotocasting, is a casting method that is used to manufacture cylindrical components with complex designs and shapes. This casting process involves spinning the casting mold in a centrifuge at high speed and pouring liquid metal into the mold. ......
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......
