Material Testing of Copper by Extrusion-cutting

Procedia CIRP, 2017
Abstract An investigation was carried out on the use of extrusion-cutting as a material test method operating at severe conditions of strain, strain-rate and temperature, such as in machining. In extrusion-cutting, a shoe constrains the chip back surface producing a geometrically defined orthogonal cutting process which can be modelled using methods ...

Influence of plastic formation parameters on structural characteristics of thermoelectric material during hot extrusion

Modern Electronic Materials, 2017
We used mathematical modeling to compare the stress and deformation in a Bi0.4Sb1.6Te3 solid solution base thermoelectric material for extrusion through different diameter dies. The results show that extrusion through a 20 mm diameter die produces a more

Instable Material Flow in Extrusion and Upsetting

CIRP Annals, 1982
In spite of precisely controled tooling the shape and dimensions of extruded cans sometimes vary considerably during production. This phenomenon happens in all forming operations which include an upsetting process such as upsetting, heading, flattening, backward can extrusion etc. Further, experiments brought up the evidence of an instable shift of the

Optimizing the Zn and Mg contents of Al–Zn–Mg wrought alloys for high strength and industrial-scale extrudability

Journal of Materials Research and Technology
High-strength Al alloys of the 7xxx series are promising candidates for further light-weighting of car bodies. However, they are difficult to process by extrusion: complex geometries in particular pose a major challenge due to high extrusion pressures ...

A Numerical Study on Co-Extrusion to Produce Coaxial Aluminum-Steel Compounds with Longitudinal Weld Seams

Metals, 2018
The use of lightweight materials is one possibility to limit the weight of vehicles and to reduce CO2 emissions. However, the mechanical properties and weight-saving potential of mono-materials are limited.
