PRODUCTION OF HOT-STRAINED POWDERS Russian patent published in 2015 - IPC B22F7/04 B22F5/00 B22F3/14

Abstract RU 2541242 C1

FIELD: metallurgy.

SUBSTANCE: this process comprises mechanical alloying of the aluminium-based charge by carbon at high-power mill, forming the blank and its hot processing by pressure. Said aluminium-based charge is produced by mechanical and chemical activation of PA-4 aluminium powder along with 18 wt % of silicon powder for 1 hour in saturated water solution of orthoboric acid. Hot processing of billet by pressure is performed at compaction by 17-70 MJ/m³.

EFFECT: hardness and mechanical properties sufficient for production of ICE cylinder liners.
