Recovery spectrum of Al 99·9995 at. % was measured by means of electrical resistivity after deformation in tension at 78 K. A great attention was paid especially to the analysis of high temperature stages IV and V. The analysis was carried out with the help of TEM, X-ray analysis, light microscopy and mechanical testing. Recovery spectrum of yield stress was measured simultaneously with the electrical resistivity one and the contributions of different recovery processes to the overall softening was established.
