Effect of annealing on mechanical, elastic and microplastic properties of aluminum alloy AD1 in various structural states

The work studied the effect of isothermal annealing in the temperature range 50–300$^\circ$C on the structure, microhardness, elastic and microplastic properties of aluminum alloy AD1 in various structural states. Structure studies were carried out using electron backscatter diffraction, transmission electron microscopy, X-ray diffraction and densitometry. A temperature range has been determined that ensures the stability of the above characteristics of the AD1 alloy.
