I'm glad to share with M&MConsulting | a Cogne Acciai Speciali Supplier follower my last research article, entitled: "Improved Metallurgical Assessment of XCr23 Wear Resistant Cast Iron Plates as Failure Analysis Research of April 2024" Abstract: My article of December 2023 [1, see article reference] described the metallurgical features of an XCr23 | EN-GJN-HB555 White Cast Iron plate, which I found as a scrap part of wear resistant parts of a rock crushing machine. Being my first study of this alloy, I thought to get a better insight in its properties by another scrap part of the same alloy, which came out of the same rock crushing machine’s manufacturer warehouse and was casted by its same supplying foundry. I’ve later found a literature review by M. Ngqase and X. Pan [2, see article reference], which comprehensively described heat treatments of XCr23 and compared them with SEM-BSE and XRD investigations of as-casted and heat treated XCr23 samples (Annealing (Destabilization) and Hardening + Tempering, namely those of samples investigated in [1, see article reference], which I will hereinafter describe), with a focus on microstructural evolution and elemental partitioning from casting up to heat treatments. Keeping [2, see article reference] as reference, I’ve investigated samples which I previously cut-out via waterjet technique from the new scrap part, like it is shown in Figure 1. XCr23 hardness was measured to be 53 HRC, equivalent to what reported in [1, see article reference]. 👉 Link: https://lnkd.in/dyJ3KhqB

What is Powder Metallurgy? Powder metallurgy is a manufacturing process that produces precision and highly accurate parts by pressing powdered metals and alloys into a rigid die under extreme pressure. Powder metallurgy has become the essential process for the production of bushings, bearings, gears, and other parts.

Aluminum metallurgy is the process of extracting, purifying, and making alloys from aluminum. Learning to do it requires significant training from certified experts. This is what aluminum metallurgy training entails, and how to get started: https://lnkd.in/eZG5B_w9 #Aluminum #AluminumMetallurgy #Manufacturing

"Smelt" and "melt" are two related but distinct terms used in the context of metallurgy and metalworking: Smelt: "Smelt" refers to the process of extracting a metal from its ore by heating and reducing it. It involves the separation of the metal from its ore through a chemical reaction, typically using heat and a reducing agent. The smelting process often involves the use of a furnace or smelter, where the ore is heated to high temperatures in the presence of a reducing agent (such as carbon) to remove oxygen and other impurities, leaving behind the pure metal. Smelting is commonly used in the production of metals such as iron, copper, lead, and zinc, where the metal is extracted from its ore and transformed into a more usable form. Melt: "Melt" refers to the process of liquefying a solid material, typically a metal or alloy, by heating it to its melting point. When a solid metal or alloy reaches its melting point, it transitions into a liquid state. Melting can occur in various contexts, including metal casting, welding, and metal recycling. For example, scrap metal may be melted down in a furnace to produce molten metal for casting into new products. The melted metal can then be poured or formed into molds, ingots, or other shapes to create finished products or intermediate materials for further processing. In summary, "smelt" specifically refers to the extraction of metal from its ore through a reduction process, while "melt" refers to the process of liquefying a solid metal or alloy by heating it to its melting point. Both processes are essential in metallurgy and metalworking for producing and shaping metals into various forms for industrial applications.

What is electroslag remelting(ESR)? Electroslag remelting (ESR) is a special metallurgical method mainly used for refining various alloy structural steels, heat-resistant steels, bearing steels, die steels, high-temperature alloys, etc. The basic principle is to use the resistance heat generated by the current passing through the molten slag to remelt and refine metals or alloys, and to sequentially solidify into steel ingots or castings. During the electroslag remelting process, metal droplets come into full contact with high-temperature, high-basicity molten slag, resulting in strong metallurgical chemical reactions that refine the metal. The main functions of electroslag remelting include: 1. Improving metal purity, enhancing ingot crystallization, and removing inclusions. 2. The slag system of the electroslag remelting furnace plays a significant role in heat source, protection, shaping, and metallurgical chemistry, greatly affecting product quality and technical-economic indicators. 3. Products from electroslag remelting have characteristics such as metal purity, dense organization, uniform composition, good shaping, smooth surface, and excellent service performance. 4. Electroslag remelting technology can save energy, improve production efficiency, and reduce production costs. The key technology of the electroslag remelting furnace is the slag system, and the chemical composition of the slag has a significant impact on product quality. The characteristics of the slag include: - Having a higher resistivity to generate sufficient heat during melting. - Having a certain basicity for good deoxidation and desulfurization effects. - Not containing stable oxides, such as MnO, FeO, etc. - Having good fluidity to ensure full convection heat exchange and liquid physical chemical reactions at high temperatures. The application range of electroslag remelting furnaces is extensive, not only can it produce various steel grades but also can be used to produce large high-quality alloy steel ingots, special-shaped castings, etc. Through electroslag remelting technology, high-strength, plastic and tough steel can be produced, which is used in high-end equipment manufacturing fields such as aerospace and military industries.
