Forging of Solid Powder Discs of Large Slenderness Ratio
نویسندگان
چکیده
The paper reports an investigation into the forging of solid powder circular disc with large slenderness ratio, between two flat dies. The deformation pattern during the operation is influenced by many factors, which interact with each other in a complex manner. The decisive factors are the interfacial conditions, initial relative density of the preform and the geometry of the preform. An attempt has been made for the determination of the die pressures developed during the forging of a circular disc with large slenderness ratio using an upper bound approach. The results so obtained are discussed critically to illustrate the interaction of various process parameters involved and are presented graphically.

An Upper Bound Solution for Closed Die Forging of Sintered Polygon
The paper reports on an investigation into the various aspects of closed die cold forging of polygonal powder preforms, which have been compacted and sintered from atomized powder. It is found that for certain dimensional ratios of the preform the die pressure is minimum. An attempt has been made for the determination of the die pressures developed for given geometries of the disc during the cl...
متن کاملDifferent methods of forging; applications and obstacles
Forging is a manufacturing process that consists of shaping the metal using localized compression forces. The blows are delivered with a hammer (often an electric hammer) or a die. In this paper, different methods of forging (multi-directional forging, hot forging, near-beta forging, multi-axial forging, direct powder forging, warm forging and ring forging) are discussed. The main problems that...
متن کاملStability analysis for forging of porous bodies
The continuum theory of sintering is used for the analysis of the stability of forging of a cylindrical powder specimen. The constitutive properties of the powder material are assumed to follow a power-law creep relationship. Temperature-coupled linear non-uniform stability analyses are carried out. Stability maps are obtained for forging of copper powder components.

It reflects clearly the importance to combine physical measurements and texture analysis. Several factors a...
متن کاملDetermination of Load and Strain-Stress Distributions in Hot Closed Die Forging Using the Plasticine Modeling Technique
An axisymmetric hot closed die-forging process has been studied by physical modeling technique using the plasticine. To observe the material flow pattern, layers of plasticine with different colors were used. The normal direction to the layers was considered a principal direction. The strain distribution was obtained by measuring the thickness of the plasticine layers. Based on the strain distr...
