Abstract
	This article presents the issue of the compaction of  1 µm aluminium powder by the forward extrusion method at different thermodynamic conditions. Experimental systems for two-sided pressing and subsequent forward extrusion process at different reduce ratios are presented in detail.  The methods of the planned experiment are conducted under experimental analyses and result in variations of various extrusion temperatures, deformation rates, and reduce ratios. Initial, precompact density factors of the compacts were obtained by a two-sided pressing process. Compression tests are realized at cold one dimensional pressing without special treatment of contacts planes and without use of lubricant. There wasn`t evaluated change of original cylindric shape of experimental specimens. Function relation ? = f(?), where ? = ln h/h0 was calculated from function relations F = f(?h). The highest deformation energies were identificated on compacts produced at tepmeratures of 300 and 450°C. Functionalities ? = f(?h), Hollomon`s exponential functions as well as total deformation energy are presented too. Deformation hardening exponents at tensile test of compacts on basis of 1µm aluminium powder were analyzed. Deformation hardening exponents were unambiguously function of diffusion processes which were very probably initiated at process of compactation. Deformation hardening exponents had value from n=0,63 for compact produced at 300°C to n=0,9 for compact produced at 450°C. Tensile tests were realized at static conditions and are like the compression tests presented in detail. Metallographic and REM analyses allowed the structures of fractured surfaces to be evaluated.
