Abstract : The article reports on the nature and results of tests conducted on aluminum alloy AMTs-AM to determine whether such mechanical properties as yield point, tensile strength, and fatigue limit are affected by the type of forging used in preparing the specimens (regular forging and explosive forming). It was found that: (1) In explosive forming, strength characteristics are higher but ductility is lower than with regular forging, (2) an especially noticeable difference is observed at low temperatures, (3) fatigue strength with explosive forming is higher, (4) the time of aging of the material also affects the mechanical properties.
