Transverse Cracks on the Surface of Steel Ingots and Their Effects
Abstract Steel ingot surface crack refers to a kind of internal damage mode of steel ingot which appears on the surface of steel ingot as a visible crack. It is difficult to predict the width and depth of the crack, so it often has a certain impact when using. Therefore, it is necessary to study th......
Basic Types of Corrosion of Aluminum and Aluminum Alloys
The Basic Types of Corrosion of Aluminum and Aluminum Alloys
When comparing the corrosion characteristics of aluminum and aluminum alloys to other materials, it is important to first understand the basic types of corrosion that this metallic element is susceptible to. For example, aluminum has a ......
hydrogen corrosion
Hydrogen Embrittlement
Hydrogen embrittlement is a unique form of material degradation. It is caused by the accumulation of atomic hydrogen within a material, eventually leading to catastrophic failure and irreparable damage. It affects a wide range of materials and many structural components, an......
Corona treatment and single layer coating
Corona treatment and single-layer coating
Corona treatment is a type of surface coating technology used to modify and coat the surfaces of materials. It is a form of electrical discharging by a device known as a corona that sends an electrical charge to the material. The resulting plasma that deve......

Research on Simulation Technology and Internal Quality Control of Large Forge
Abstract
Forging technology is a kind of processing technology with high efficiency, good reliability and wide application, and large forgings have the characteristics of large size, complex shape, high precision and h......
Die forging lubrication
Friction and lubrication
Friction is the force generated between two surfaces when they are in contact and are moved relative to each other. Friction is sometimes seen as beneficial because it is essential to prevent slipping, reduce wear and tear, provide a better grip and reduce noise. But ther......
Forging Technology: Numerical Simulation of the Principles and Procedures of Computer Simulation of the Stamping Forming Process
Numerical Simulation of Punching Forming Process and Computer Simulation Principle and Steps
Abstract
Punching forming process is a general metal forming process. In recent years, cold stamping technology has also been more and more applied in manufacturing and engineering fields.cold stamping i......
Defects and Prevention of Liquid Die Forgings: Extrusion and Cold Shut
Introduction
Die casting plays an important role in the manufacturing industry due to its ability to produce complex shapes with precision and repeatability. However, due to the rapid cooling of the molten metal inside the cavity, dimensional and surface variations can occur due to shrinkage or p......
Austenitic dendrite formation
Austenite Dendrites Formation
Austenite dendrites form when a material undergoes phase transformation from solid austenite to liquid phase. The phenomenon is similar to crystal growth and dendritic growth in metals and alloys, in which successive crystal growth results in dendritic-shaped feature......
