ASTM A638M-1995 is an international standard for precipitating hardening iron-based supermartensitic rods, forgings and billets. This specification covers UNS S44600 and S44800 grade......
GB 12827-91 standard reference acetylene carbon black and identification method
Carbon black refers to black powdery or granular material, which is composed of many tiny particles with the average particle size of between 10 and 2000 nanometers. It is composedot many carbon atoms buthydrophobic in nature. Carbon black can be prepared by pyrolysis of hydrocarbons such as coal ......
GB/T 4162-91 Ultrasonic Inspection Method for Forged Steel Bars
材料
Abstract
Ultrasonic testing is an important technique for detection of rolling defects in steel bars. Ultrasonic testing is typically used to detect internal flaws, such as cracks and other discontinuities, that cannot be detected by visual inspection. GB／T 4162–91 regulates the ultrasonic ......
Chemical composition of austenitic stainless steel (smelting analysis)
Austenitic Steels
Austenitic steels are steels which have been alloyed with a range of different alloying elements to make them suitable for use in a variety of critical applications such as jet engines, ships, nuclear power plants and cryogenic applications. Austenitic steels are among the most ......
Grain Oriented Silicon Steel Strip (YB/T5224-1993)
Crystallographic Orientation of Silicon Steel Strip
Introduction
Silicon steel strip (YB/T5224-1993) is produced from strips of cold rolled steel sheets. It has a silicon content between 0.70 - 1.20% and is widely used to improve the performance of electrical steels for applications in electrica......
Common vocabulary of mechanical engineering materials (Part 2)
Mechanical Engineering Materials - Glossary
Stress relief: The process of removing residual stresses from a material. Heat is applied to a limited area at a temperature low enough that the parent materials properties are not altered, then allowed to cool to room temperature. The end result is a r......
Wettability of Mineral Surfaces
Wettability of Mineral Surfaces
Introduction
Mineral wetting is an important and complex phenomenon related to the interactions between a solid surface, liquids, and gas phases. The wettability of a mineral surface is defined as its ability to spread and form a thermodynamically stable interface......
Mineral Surface Analysis
Minerals are a vital part of life. They can be found deep in the ocean and can also be found high in the mountains. Minerals are used to create the tools, machines, and components we use on a daily basis. They are essential to the process of building modern technology and creating the items we use ......
The characteristics of the control object in the beneficiation process
Introduction
Effective and efficient ore selection processes are paramount in the successful exploitation of mineral resources. The ore selection process is a complex process that is usually controlled by a range of infrastructure systems in order to maintain a balance between the economics of th......
