dcterms:description
This research concerned the whole production of UFG materials, using Severe Plastic Deformation (SPD). Use of these materials is very versatile – either directly as semi-products for subsequent further processing with lower number of operations (created structure is preserved in final products), or for production of final products from semi-products. Contribution concerned the whole production of UFG materials, using forming process DRECE (Dual Rolls Equal Channel Extrusion). The strip sheet with dimensions of 58 x 2 x 1000 mm is inserted into the workspace and forced by feed roller with help presser rollers to the forming tool. There is intensive plastic deformation. Cross-section and length of the strip stays unchanged. Forming process is repeated several times. Severe plastic deformation realized in this way it allows to refinement of the structure. He also evaluated the influence of heat treatment on the mechanical properties and structure. The values of hardness of the formed samples were measured by Vickers method. Preliminary metallographic analysis was performed for the approximate information, if really there is a refinement of the structure.
