Producing of ultrafine grained composites with a large uniform elongation by twist extrusion: Mathematical simulation

Аннотация

The conditions of production of a composite material of the ultrafine grained shell–coarse-grained core type are determined by mathematical simulation of twist extrusion. A combination of regions with ultrafine grained and coarse-grained structures in the sample volume leads to a substantial increase in strength of the sample at a retained large uniform elongation.
