In 1975, a small group of entrepreneurs from Silicon Valley came together with a common goal – to start a new business with the goal to push the edge of technology. They had no money and no experience, but they had passion and an idea to revolutionize the way people interact with computers. They ......
Rolling in vacuum and protective gas
Rolling in Vacuum and Protective Atmosphere
Introduction
Rolling is the process of reducing the thickness of a metal workpiece by passing it through a pair of rotating metal rolls (rollers); when heated and subjected to amplification, it also increases its length. It is one of the most widely us......
Classification of eutectic clusters in gray cast iron
Introduction
Gray cast iron is one of the most widely used ferrous alloys for various mechanical components owing to its desirable combination of mechanical efficiency at the low cost. It consists of the combination of pearlite, ferrite and graphite.As an iron-carbon alloy, the distribution of th......
Ferroboron (GB/T5682-1995)
Introduction
Boron-Iron (B-Fe) is a special alloy, containing two elements: boron and iron. It is mainly used in the production of magnetic alloys, special steel, heat-resisting alloys, heat-treating alloys, and hard metal alloys. Its characteristics of hardenability, compressive strength, corros......
