Liquid-phase nucleation and evolution as a cause of superplasticity in alloys of the Al-Ge system

Autor: R. I. Kuznetsova, N. N. Zhukov, V. P. Poida, V. F. Klepikov, V. V. Bryukhovetsky

Publikováno v: physica status solidi (a). 202:1740-1750

The kinetics of phase transformations taking place under conditions of superplastic flow in the matrix alloys of the Al–Ge system was studied. It has been found that these alloys manifest superplasticity in the nonequilibrium state that is characte

Structural peculiarities of the superplastic behaviour of the alloy Al–4 wt% Ge due to porosity

Autor: N. N. Zhukov, R. I. Kuznetsova

Publikováno v: Physica Status Solidi (a). 50:385-391

The development of grain boundary porosity is investigated at creep of coarse-grained alloys Al-4 wt % Ge which show superplastic behaviour in the solid solution temperature range. Under optimum conditions of superplasticity (T = 500°C, σ = 3 MN/m2
