Due to product features such as production quality and high surface quality, cold forging extrusion methods are widely used in the of fasteners. Extrudability plays a key role during process is affected by many parameters. Die shape characteristics directly affect deformation. In particular, deformation hardening influenced characteristics. The also significantly affects mechanical properties. ...

the aim of the paper presented here is to develop the ti - micralloyed steel in otrer to oprtmize the mechanical properties after direct quenching from hot forging temperature. for this purpose, seven melts containing various amounts of titanium were prepared and cast in metal and sand molds. from the ingots, cast in metal mould, tractor links were produced by hot forging. the produced links we...

To assess the wear of hot stamping tool, a model punch deformation under influence thermal and mechanical loads was developed. The shape relative position die were designed to localize maximum contact at predetermined location. It assumed that is caused by removal surface metal layer, due decreasing its strength during plastic deformation. Simulation performed finite element method in Deform so...
