Identification of quenching cracks and non-quenching cracks
Quenching Crack and Non-quenching Crack Identification
Quenching crack (also known as quench crack or quenched fracture) is a form of plastic deformation that occurs in steel parts during heat treatment. Quenching cracks happen during the quick cooling after austenitizing. When the cooling is too......

Effect of Heating Temperature and Holding Time on δ Phase Content in 1Cr17Ni Steel
Impact of Heating Temperature and Holding Time on δ Phase Content in 1Cr17Ni Steel
1Cr17Ni steel is an austenitic stainless steel, characterized by excellent corrosion resistance and heat resistance. As a result, 1Cr17Ni steel has wide applications in the fields of chemical, petrochemical and th......
Effect of Annealing Temperature on Microstructure and Hardness of Chilled Low Chromium Molybdenum Ductile Iron Roll
Effect of Annealing Temperature on Microstructure and Hardness of Cold-Worked Low Cr-Mo-Ball Iron Rolls
Abstract
In this paper, the effects of annealing temperature on hardness and microstructure of cold-worked low Cr-Mo-ball iron rolls were studied. Metallographic analysis and nanoindentation t......
electron diffraction
Introduction
Electron diffraction (ED) is a form of diffraction that involves the scattering of electrons by matter to study the structure of matter on the atomic level. It is one of the most powerful techniques available to scientists today in order to obtain detailed information about the atomi......
Disproportionation metallurgy
What Is Metallurgy?
Metallurgy is a form of engineering and science that studies the physical and chemical behavior of metallic elements, their intermetallic compounds, and their mixtures, which are known as alloys. Traditionally, metallurgy is divided into two categories: extractive metallurgy a......
Composite material inspection
Composite materials have become widely used in recent times as alternatives to traditional materials. Their low weight, high strength, superior thermal and electrical properties, and ability to be recycled make them attractive for a range of applications. As with any material, to ensure the desire......
Research on Technology of Production Oriented Silicon Steel by Continuous Casting and Rolling of Thin Slab
Research on Directional Silicon Steel Production Technology for Thin Slug Continuous Casting and Rolling
Abstract
This paper takes thin slab continuous casting and rolling production as the research background and further studies the general principles and technical characteristics of directiona......
Low-magnification structure of continuous casting slab (low-magnification structure)
Low-magnification organization of continuous cast billets
Continuous casting billets are metal billets that are formed through a continuous casting process, a process through which metal is heated to its liquid state, poured into a casting mold, and then rapidly cooled to form a solid. Continuous......
Tracking the Transition of Sulfides in Steel
Tracking the Migration of Sulfur in Steel
Sulfur is an important element for metallurgical engineering. It is often found in steel and has a major role in the overall properties of the steel. Its presence and migration can be very beneficial in certain cases but detrimental in others, depending o......
