Hot closed die forging is a regular process applied to manufacture metallic components used in supporting and fixing cable conductors in electric power transmission lines. In this forming process, the final microstructure of the workpiece depends on the control of several processing parameters. In this study, simulation of the industrial forging process of a ball hook component was performed us...

Abstract—Closed die forging is a very complex process, and measurement of actual forces for real material is difficult and time consuming. Hence, the modelling technique has taken the advantage of carrying out the experimentation with the proper model material which needs lesser forces and relatively low temperature. The results of experiments on the model material then may be correlated with t...

The cold compaction of an aggregate of powder is treated from the viewpoint of crystal plasticity theory. The contacts between particles are treated as compaction planes which yield under both normal and shear straining. The hardening of each plane represents both geometric and material hardening at the contacts between particles; the macroscopic tangent stiffness can be written in terms of the...

A closed die forging process was developed to successfully forge an automotive suspension component from AZ80 Mg at a variety of different temperatures (300 °C, 450 °C). The properties the forged were compared and contrasted with other research works on both intermediate full-scale level. monotonic response, as well stress strain-controlled fatigue behaviours, characterized for materials. Stres...

The paper presents an investigation on the effect of process variables and material condition on forgeability of magnesium wrought alloys of Mg-Al-Zn group, AZ31, AZ61 and AZ91. The experimental work includes studies of forging capabilities of the alloys in closed-die forging at hot and warm-working temperatures. Forging tests are performed for material both in as-cast and asworked condition, f...

Ressourcenknappheit, Stakeholderforderungen und steigendes Nachhaltigkeits-bewusstsein von Konsumenten drängen Unternehmen dazu, ihre Supply-Chain nachhaltig auszurichten, sodass neben ökonomischen Zielen auch ökologische soziale Aspekte Berücksichtigung finden. Die Closed-Loop Supply Chain spielt als Lösungsansatz in der Diskussion nachhaltiger Wertschöpfungssysteme eine wesentliche Rolle, jed...

‎in this paper, a new class of fuzzy sets called fuzzy strongly ${{g}^{*}}$-closed sets is introduced and its properties are investigated. moreover, we study some more properties of this type of closed spaces.
