The subject of the presented paper is the modelling of strain-stress relationship, which is the main mechanical property characteristic of the behaviour of C45 grade steel subjected to plastic deformation in semi-solid state. The methodology of yield stress curves development requires high accuracy
Smooth round bars were produced from conventional non-modified cast alloy, A356, by semi-solid extrusion after isothermal holding in mushy zone. Extrusion process was carried out in an apparatus, designed and prepared for this purpose at a ram speed, 2.5 mm/s. Three forming temperatures: 560, 570 an
