Abstract

The microstructure and mechanical properties of magnesium alloys are studied after extrusion. Shapes are obtained from commercial magnesium alloys with the help of a rarely used technology, i.e., hydrostatic extrusion at 100°C (a temperature much lower than the one at which new slip planes are activated). All the tests are performed with allowance for typical parameters, such as the rate of extrusion and the degree of drawing, in order to choose appropriate conditions for fabricating a material with exceptionally fine grains, which is typical for a structure formed as a result of equal-channel angular extrusion (ECAE). The constraints connected with this kind of treatment are discussed as well as the effects of its parameters on the microstructure and mechanical properties of the extruded shapes.
