Metallographic diagram of granular bainite 12Cr2Ni4A
Introduction
Grain-oriented ferritic alloys, also known as Grain Boundary Enhancement Alloys or GBEA, have been around for decades, but until recently their importance has been largely overlooked. These alloys are known for their high strength and their ability to absorb impact, making them ideal......
Metallographic diagram of granular bainite CrMo
Grain-Boehmite of CrMo Metallographic Sample
CrMo is an alloy of chromium and molybdenum commonly used in the manufacture of engine parts, tools, and other machine parts. In this paper, we will be studying a grain-Boehmite of CrMo, a metallographic sample consisting of small grains of the materia......
Non-metallic inclusions in GCr15SiMn steel
Abstract
The GCr15SiMn steel is a kind of low carbon steel – chromium bearing steel grade. It has been widely used in the production of mechanical components due to its good mechanical performance and wear resistance. It is well known that the nonmetallic inclusions in the GCr15SiMn steel have g......
Low microstructure and non-metallic inclusions in GCr15 steel
GCr15 Steel Low Magnification Microstructure and Non-Metallic Inclusions
GCr15 steel is one of the chromium-containing steels and is used for applications such as ball bearings and razor blades. The manufacture of such components requires an adequate understanding of the metallurgy and working ch......
Metallographic diagram of HT250
Microstructure of HT250
HT250 is a type of heat-resistant high-strength aluminum alloy widely used in aerospace, defense and other industries. Therefore, its microstructure has received widespread attention. In order to study the microstructure of HT250 more accurately, the microstructure of HT25......
Metallographic diagram of Ineoloy800 (cold-rolled and annealed after solid solution)
INCONEL® alloy 800 is an austenitic nickel-chromium alloy with a controlled carbon content. It is particularly useful for its excellent resistance to carburization and oxidation. Alloy 800 also has a very good strength and excellent resistance to stress rupture and creep. It resists nitridation a......

The 30MW Generator Rotor Core Protection Material: Microstructure Analysis
This paper investigates the 30 mega-watt (MW) generator rotor core protection material, with an emphasis on the microstructures obtained when it is heated to different temperatures. A full-volume scanning electron microsc......
Metallographic diagram of Q235 (slow cooling after carburizing at 950°C) carburizing treatment
Q235 carbon steel is a low-carbon steel alloy typically used in structural steel applications. It is a popular material for structural components, primarily due to its strength and formability. In certain applications, however, Q235 requires a heat-treatment step to increase its toughness and dime......
Introduction to Martensitic (M) Metallographic Structure
Martensite is a type of microstructure of iron-based alloys that is formed at relatively low temperatures, approximately between 200 and 900°C (392 and 1652°F). It is a metastable-phase, which is a supersaturated solid solution as compared to the equilibrium phase austenite. Martensite is a very......
