Phase Transformations of non-isothermally annealed as-cast and cold-rolled AlMnScZr Alloys
Original language description
The effect of Mn addition on the microstructure, thermal and mechanical properties in as-cast and cold-rolled Al - Sc -Zr alloys was studied. Electrical resistometry, differential scanning calorimetry and microhardness measurements were used. Transmission electron microscopy, electron backscatter diffraction and X-ray diffraction of specimens quenched from temperatures of pronounced changes in resistivity helped to identify the microstructural processes responsible for resistivity changes. The distinctmicrohardness increase observed after annealing above ~ 320 °C is caused by precipitation of the Al3Sc particles. The coldrolling prior to a heat treatment has no substantial effect on temperature position of the Al3Sc-phase precipitation. The formationof Al6Mn and/or Al6(Mn,Fe) particles is responsible for the intensive resistivity decrease of the coldrolled materials compared to the as-cast materials. Precipitation of these particles has an insignificant effect on microhardness. The a
