Modern development the technology of SHS

Abstract

Tools are usually obtained by joining the cutting part to a steel harder (by brazing, welding, gluing and by other methods). New ways of fabricating tools have been devised in which self-propagating high-temperature synthesis (SHS) heat is used not only to the cutting alloy, but also to simultaneously weld it to steel holder of the tool. High heat ability is obtained by combining aluminothermy (the thermite process) with the SHS of carbide alloys, including “carbonsteel”. The latter is a form of carbide alloys in which cobalt is replaced by tool steel.
