Abstract The current study strives to improve the precision and accuracy of a die reduce unnecessary production steps. Upset cold forging for thick coin-like carbon steel parts were studied redesigned single operation. slug used in this experiment was an annealed AISI 1020 bar sheared into cylinders having height diameter ratio (h 0 /d ) 2.07. design problem is prevent inclined surface due roug...

To realize large wind power plants in an economically feasible way, it is necessary to identify potential for lightweight design of the generator hollow-shafts, which are commonly produced by casting. The weight of these shafts can significantly be reduced by producing them by open-die forging, since the forming of the material leads to a higher strength, which allows to reduce the wall thickne...

this paper presents a hybrid method for the optimization of forging process of an aerofoil blade. preform shape and die parting-line angle are optimized in order to minimize the volume of the unfilled die cavity, material waste, forging forces. the overall optimization scheme used in this research work includes a multi-objective approach that is combination of response surface and finite elemen...

Crankshafts are the most important loaded components in the case of an automobile. In order to achieve required mechanical properties most of crankshafts for automobile are forged with micro alloyed steel. Usually, the shapes of crankshafts are complex, and many defects are induced during the process of crankshaft forging such as under-filling, laps and folds etc. In this work the forging analy...

Powder metallurgy is one way of producing complex, graded structures that could allow material systems to be produced with properties tailored individual applications. However, powder requires the semi-finished products are very similar final component. It much more economical produce simple and then combine them by forging simultaneous compaction than forming complex components desired structu...

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...
