Abstract
EN: On example of aluminum alloy AMg6 the
questions concerning development processes of
structure formation during friction stir welding are
considered. From analysis changes in technological
parameters of welding process, a qualitatively different
nature of the temperature change is determined when
approaching conditions of the super plastic deformation.
In accordance with determined heating temperatures,
effect grain size of solid solution on hardness in micro
volumes of the alloy after forming weld joint was
analyzed. From analysis dependence of micro hardness
on grain size, it is determined that as the temperature
increases, contribution to achieving conditions of super
plastic flow from the grain boundaries with large angles of
disorientation increases, and effect from solid solution
state are decreases.
