Фрикционная перемешивающая обработка алюминиево-магниевого сплава АМг6БМ с введением при обработке порошков на основе меди и медных сплавов

Abstract

The paper investigates the features of modification by powder particles of copper and copper-based alloys of aluminum-magnesium alloy AMg6BM by friction stirring treatment. The conducted studies show that in the structure of the stir zone the distribution of powder particles after one pass by the tool along the machining line is non-uniform with a high proportion of large agglomerations. The optimum number of passes by the tool to homogenize the structure is in the range of 3 to 4 depending on the powder material used to harden the aluminum alloy.
