Beschreibung
Zusammenfassung:	FIELD: aluminum alloys. SUBSTANCE: method is designed for heat treatment of high- strength constructional aluminum alloys. Aluminum alloy part batch is loaded into furnace with, preheated to a specified temperature, quartz sand particles fluidized by aerodynamically heated air. Batch is then heated to phase-conversion temperature, aged, discharged from furnace, and hardened in water. Vigorous stirring of particles enables effective heating of parts to desired temperature. Fluidization by aerodynamically heated air allows reducing power consumption, eliminating distortion in the course of heating, improving mechanical characteristics of parts, excluding explosive and fire hazard, and also ensuring economical efficiency of process. EFFECT: enhanced process efficiency.
