Defects and Countermeasures of Large Forgings: Forging Cracks
Defects and Countermeasures of Large Forgings
Large forgings are widely used in various fields such as industrial manufacturing, aerospace and military. Forgings produced with high performance, safety and reliability requirements have very high requirements for the accuracy of the forgings and re......
Defects and Countermeasures of Large Forgings: Inclusions and Harmful Trace Elements
Defects of Large Forgings and Countermeasures
Large forgings usually refer to complex and large-scale forgings that weigh more than 10 tons and are difficult to process and inspect due to their large size, complex shape, high strength and low toughness. They are mainly used in petrochemical, powe......
High Temperature Plasticity of Superalloys
Introduction
High temperature alloys refer to metal materials designed and manufacturedusing the principle of thermodynamics, thermochemistry and thermomechanics to work in harsh conditions.These alloys are usually tailor-made depending on the metal and alloy composition and the requirements of ap......
Forging technology: precipitation hardened stainless steel forging
Introduction
Precipitation hardening stainless steel forging is a forging method that uses precipitation hardening stainless steel as a material and is processed by forging. Forging can be divided into hot forging, warm forging and cold forging according to the temperature range of the processing......
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 ......
ISO 4950/3-1995 Steel delivered in heat-treated condition
IEC 60559:1989. Floating-point arithmetic
This international standard defines the characteristics of the floating-point arithmetic used in computers and other digital systems. It applies to both single-precision and double-precision floating-point formats.
The standard defines the representation......

Annealing of Steel
Annealing is a thermal process in which all types of steels, including stainless steel and carbon steel, are exposed to a heat treatment process for softening. The process involves heating steel to above the recrystallization temperature, maintaining the temperature for a p......
Ways to reduce hydrogen content in steel
Technology for Lowering Hydrogen Content in steels
1 Introduction
Steel is an important material in many large-scale engineering projects. It is widely used in infrastructure, industrial processes and in countless other applications where its strength, ductility and durability make it an ideal......
Basic knowledge of metal heat treatment (1)
Introduction
Metal heat treatment is an important part of the production process of many products. It is a process of changing the physical properties of a metal with the help of heating and cooling. The process of heat treating can be used to improve the strength, ductility and workability of met......
