flame surface quenching
Flame Surface Hardening
Flame surface hardening is a process that involves heating small portions of a metal surface to high temperatures beyond its austenite transformation temperature and then cooling it quickly. It is used to harden a select surface area, but not the entire metal part. It works......
Controlled cooling and online heat treatment technology
Control Cooling and Online Hot Processing Technology
Introduction
The control cooling and online hot processing technology is a revolutionary method used to achieve metallurgical properties in metals and alloys without the need for an additional heat treatment process. The technology involves th......
Defects often caused by improper heat treatment process after forging
Defects of Hot Worked Steel Caused by Improper Heat Treatment
Hot-worked steel is an important part of the steel industry, but it can also be one of the most unpredictable materials. Improper heat treatment can cause some common defects, such as cracking, distortion, and reduced strength. Proper ......
What method can prevent quenching crack
Introduction
Heat treatment is a process of heating and cooling metals to alter their physical and mechanical properties without changing its shape. Heat treatment is beneficial in many ways as it helps to increase the strength, hardness, and durability of the material, enabling it to perform its......
metal heat treatment
Metal Heat Treatment
Heat treatment is an important manufacturing process that is often used to manipulate the structure, physical and chemical properties of a metal working component. By varying temperatures, holding times, rate of cooling and other parameters, the microstructure of metals, su......
Forming Limit Diagram
Forming Limit Diagram
Forming Limit Diagram (FLD) is a valuable tool used to visually display the properties of metal sheets. These diagrams are graphical representations of the geometry of a forming process and can be used to predict what geometries can be produced with a certain sheet metal mat......
cross rolling
Cross Rolling
Cross rolling is a metal forming process used to reduce the diameter and improve the surface quality of a material. During the process, a metal material is passed through a pair of rollers that rotate in opposite directions. The opposite motion and pressure of the rollers compress t......
Hole expansion test
Micropile Quality Assurance and Testing
Micropiles are a type of foundation construction that is increasingly used for a variety of major structures, especially those subject to high load, vibration, and risk of collapse. Although micropiles are generally understood to provide improved structural......
The niobium solute acts to drag and prevent grain coarsening
Introduction
Niobium is a transition metal that shows useful properties in many different applications. It is often used as an alloying agent for steels, for example in superalloys, corrosion-resistant alloys, and high-speed steels, some of which contain up to 6% niobium. In its pure form or as a......
