Динамическая пластическая деформация композита Al+Al2O3, полученного методом магнитно-импульсного прессования

Abstract

In present work was made magnetic pulsed compaction of nanoscale aluminum passivated powder. After compaction the samples have been subjected dynamic plastic deformation (DPD) in a matrix of a larger size under pressure 1.5 MPa. Thanks toDPD there was a complete destruction of oxide membranes, and a structure of aluminumbasedmetal-matrix compositeswith homogeneous particle distribution was formed. This increased the electrical conductivity of the material hundreds of times.
