Structure and Properties of Al–Feti Powder Material Based on Mechanochemically Activated Alloy D-16 Turnings

Hot-worked powder materials (HWPM) based on a mixture of aluminum powder and turnings, prepared by combined mechanical activation of D-16 alloy turnings and ferrotitanium powder in a medium of water saturated solution of boric acid, are considered. Mechanical properties (hardness, ultimate shear strength, bending tests) and structure of the HWPM obtained are determined. On the basis of analyzing studies of the material’s structure and properties, a technology is proposed for obtaining HWPM based on agglomerates, including: treatment of D-16 alloy turnings together with ferrotitanium powder in a medium of water saturated boric acid solution, separation of the activated turning powder (ASP), preparation of a mixture of aluminum powder and ASP, and cold compaction; heating in an air atmosphere and hot stamping. This technology makes it possible to prepare materials with improved strength and hardness.
