Forging is a cost-effective way to produce net-shape or nearnet-shape components. Forged components are used throughout the manufacturing sector in many different applications. Owing to the lack of an accurate process model, modern forging operations still largely rely on operator skills and experience. The expertise of skilled operators can help to develop a forging process model. However, the...

Structurally porous metal sandwich panels consisting of dense face sheets and porous cores of controlled relative density can be manufactured by trapping inert gas during hot isostatic pressing and modifying its distribution via subsequent thermomechanical forming. A plane-strain solution for analyzing the open-die forging of such a plastically compressible sandwich panel is developed. An effec...

Abstract Forgings are produced in several process steps, the so-called forging sequence. The design of efficient sequences is a very complex and iterative development process. In order to automate this reduce time, method presented here, which automatically generates multi-stage for different geometries on basis component geometry (STL file). was developed closed die forging. individual modules...

The finite element method plays an extremely important role in forging process design as it provides a valid means to quantify forging errors and thereby govern die shape modification to improve the dimensional accuracy of the component. However, this dependency on process simulation could raise significant problems and present a major drawback if the finite element simulation results were inac...

A new near-net forging procedure of titanium and alloys was proposed by using a carbon-supersaturated punch die. Due to the in situ formation carbon-based tribofilm on contact interface between dies work materials, low frictional state sustained through process even high reduction thickness. The hardening suppressed during forging; an additional annealing unnecessary whole forging. Pure ?-phase...

An artificial intelligence tool is exploited to discover and characterize a new molybdenum-base alloy that is the most likely to simultaneously satisfy targets of cost, phase stability, precipitate content, yield stress, and hardness. Experimental testing demonstrates that the proposed alloy fulfills the computational predictions, and furthermore the physical properties exceed those of other co...
