Heat treatment example: heat treatment of bearing parts
Heat Treatment Of Bearing Parts
Heat treatment is one of the key processes used in the production of bearing parts. Other treatments such as hardening, annealing, and tempering are necessary to create an optimal bearing part. Heat treating bearing parts is the process of heating a piece to the de......
Design Principles of Zinc-based Alloy Punching Die
Design Principles of Zinc-based Alloy die for Stamping
Introduction
Stamping is a widely used process in many fields of engineering and manufacturing, and the key element of a successful stamping process is the die. The performance of a stamping die depends not only on its design but also on the......
New mold materials and heat and surface treatment
？
Mould materials have been continuously improving in recent years. Many new materials have been discovered and used in different moulds. Although these new materials can be used to increase efficiency and reduce costs, it is not enough to just choose the right material. Some extra treatments such......
Forging technology: heating process for titanium alloy forging
Titanium Alloy Forging Heating Process
Titanium alloy forging heating process, which is also known as titanium alloy forging, is a technique used to shape titanium alloys, usually in a forge. It involves heating a piece of titanium to a specific temperature, then forming it into a desired shape b......
The main defects of forging raw materials and the forging defects caused by them
Introduction
Forging is an important metalworking process that involves forming and reshaping the metal by applying force. Metal forging is an integral part of many industries including automotive, aerospace, shipbuilding, and engineering. The metal forging process involves heating the metal to t......
Powder hydrogen loss test
Hydrogen Attack Test
Hydrogen attack testing is a vital process used to detect any hydrogen embrittlement from within a material. Hydrogen embrittlement can occur if a material is able to absorb hydrogen atoms from its environment, causing the material to become weak, which consequently leads to ......
Heat treatment and post-weld heat treatment of American standard pressure cast steel
Heat Treatment and Post Weld Heat Treatment of American Standard Pressure Cast
Steel
Introduction
In the industrial sector, American Standard Pressure Cast Steel (ASPCC) is one of the most widely used steels for structural applications. A major benefit of using ASPCC is that its properties are i......
Common Defects of Nitriding (Soft Nitriding)
Leakage of N2 in NF3 Etching
As the need for complex semiconductor wafers and advanced packaging technologies continues to grow, so does the need for sophisticated high-throughput chemical etching processes. Nitrogen trifluoride (NF3) is a key etchant used in the semiconductor industry, as it is ......
Mechanism of contact fatigue spalling
Fatigue of metals is one of the most important failure mechanisms in engineering. Tensile tests have been used to study the fatigue behavior of metals. The reduction in load-recycling load ratio, or the fractional toughness, can be used as a measure of fatigue strength. The fractional toughness is......
