Commonly used English vocabulary for heat treatment
Heat Treatment
Heat treatment is a process used to alter the physical, chemical, and sometimes mechanical properties of a material. The most common application is in metalworking, where heat treatment is used to induce desired physical properties such as hardness, ductility, tensile strength, an......
Mineralogical analysis of beneficiation products
Mineralogical Analysis for Selecting Mineral Products
The selection of mineral products can be made on the basis of mineralogical analysis. Mineralogy is the scientific study of minerals, crystal structures, and their physical properties. This analysis provides an assessment of the components and......
Example of heat treatment: heat treatment of curved parts (below)
The second step in the process of heat treating an automotive part is to ensure the correct cooling rate. After heating, the part needs to cool at a rate that will produce the desired impact strength and the most consistent across the entire part. If the cooling rate is too slow, it can cause warp......
Ultra-low carbon HSLA forgings with good structure and properties
Ultra Low Carbon HSLA Forgings
Steel is one of the oldest and most widely used materials in engineering applications. Steel forgings have been used for a variety of purposes since the Bronze Age and are still used in a range of industries from aerospace to automotive. However, steel is becoming i......
Effect of Shielding Gas Composition on Chemical Composition and Intergranular Corrosion Resistance of 18-8Ti Steel Weld
Abstract
The effect of gas protection composition on the chemical composition and intergranular corrosion resistance of 18-8Ti welds was investigated in this paper. The welding operation was performed using the TIG welding process with different gas protection composition, such as argon–carbon d......
YS/T318—1997 copper concentrate
Copper Ore
Copper ore is one of the most important minerals used in industry. It is used in various applications from electrical wires and plumbing pipes to jewelry and decorative artwork. Copper ore is mined from the ground and refined through various processes that reduce its impurities. Copper......
The use of common bearing steel
Uses of Common Bearing Steel
Bearing steel is a special type of steel used in the manufacturing of bearings. It is high in carbon content, and contains other alloying elements to provide high hardness, wear resistance and fatigue strength. Bearing steel is one of the most important materials in e......
Metallographic diagram of 15 steel (directly quenched after liquid carbonitriding)
A microstructure of C15 steel examined from metallographic standpoint can be observed in Figure 1. This sample has been heat-treated by liquid carbonitriding and heat treat in the same way. C15 steel is a martensitic carbon steel that can be used for a variety of applications, including bearings a......
Understanding of vacuum heat treatment technology, surface treatment technology and pre-hardening technology
Vacuum Heat Treatment Technology
Vacuum heat treatment technology is a technique used to heat and treat materials to improve their quality, strength and other properties. It is a process whereby the material is heated in a sealed environment and exposed to a vacuum, which reduces the amount of o......
