The shape of extrusions and intrusions was documented and the kinetics of the extrusion growth was studied in both steels.
True shape of extrusions and intrusions and the path of initiated fatigue cracks were assessed in three dimensions by FIB micro-tomography.
Three different coating ratings are generated based upon maximum extrusion force, standard deviation of the force, and the characteristic shape of the extrusion curve.
To investigate the optimum shape of the designed extrusion dies, that yield the lowest upper-bound for a given reduction in area, die length, off-centric positioning and frictional conditions a computer program was developed.
We show four aspects of this material: (1) The colloidal gel material holds its shape after extrusion.
The goal of the present paper is to develop a criterion and use an adaptable die design methodology that will allow the prediction of extrusion die shapes that produce minimum distortion in axisymmetric product.
Different amounts of used powders were mixed according to mixture design algorithm and shaped by extrusion technique in the form of Raschig ring.
The effect of flow passage length in the die cavity and extrusion wheel velocity on the shape of aluminum sheath during the continuous extrusion sheathing process was analyzed by using finite element methods based on software DEFORM 3D and experimentally validated.
Finally, effects of extrusion process parameters on the shape accuracy of five-lumen micro tubes, evaluated by the ovality of profiles, were investigated experimentally with polypropylene as extrusion material.
The effect of wall friction, die shape and extrusion speed on LPM in a cylindrically axisymmetric ram extruder is investigated using a two-dimensional finite element model of paste extrusion based on soil mechanics principles (modified Cam-Clay).
The effects of the process parameters, such as extrusion temperature, extrusion speed, dimensions of billet, and location of holes on the extrusion load and the shape of extruded tubes were then studied by the finite element analysis.
