A large specific surface area of WC nanopowder determines its high chemical activity and makes it very sensitive to various impurities, among which oxygen is most harmful unavoidable. During heating, interacts with carbon being removed in the form CO/CO 2 , finally leads appearance embrittling η-phases hard alloy, abnormal growth grains, formation a porous microstructure. To prevent heavy decar...

A study has been carried out on one of the first generation automotive assembly plant in Nigeria their current level operations, automation and how to migrate industry 4.0. In process, a comprehensive review disruptive technology manufacturing sector was find global industries. It discovered that 4.0 is already fully operational key plants. This positively impacted industries it comes with many...

*Member of ASM International arburizing has been a popular method for obtaining a unique balance of properties in steels for many years. Steels with low carbon contents are characterized by good toughness and good ductility, but low strength and low wear resistance. By locally increasing the carbon content at the surface, followed by heat treatment to produce a very high hardness in this layer ...

The purpose of a furnace atmosphere varies with the desired end result of the heat-treating process. In general, the atmospheres used in the heat-treating industry have one of two common purposes: •To protect the material being processed from chemical reactions that could occur on their surfaces (e.g. oxidation), that is, to be passive (or chemically inert) to the metal surface. •To allow the s...

AOD (Argon Oxygen Decarburization) smelting low carbon ferrochrome is extremely complex and multiphase, which is carried out under high temperature chemical process of nonlinear physical. The discretion of the phosphorus’ impurity content is an important factor to affect the quality of ferrochrome products. In order to predict the quality of the product control, it is an optimization method tak...
