Influence of ECAP on precipitate distributions in a spray-cast aluminum alloy

Experiments were conducted to evaluate the influence of equal-channel angular pressing (ECAP) on the mechanical properties of a spray-cast aluminum 7034 alloy. In the unpressed condition, the grain size of the alloy was ∼2.1 μm and the microstructure contained an array of rod-like η-phase (MgZn2) pr...
