Tool for warm and hot forgings and process for manufacturing the same |
摘要 |
A tool for warm and hot forgings is proposed which is made by bonding cemented carbide to steel by applying electron beams or laser to the joint. The cemented carbide includes a hard phase of tungsten carbide and a binder metal phase containing at least one of Ni, Co and Fe, and at least one of Cr, Mo and W, the latter forming a solid solution. A process for manufacturing such a tool is also proposed in which unfocussed high-energy beams are applied to each side of the joint and focussed beams are then applied to a point slightly away from the joint toward the cemented carbide.
