PHASE-TRANSITIONS UNDER MECHANICAL STRESS ES - PRODUCTION, USING MECHANOSYNTHESIS OF NANOMATERIALS (METALLIC ALLOYS, SEMICONDUCTORS, CERAMICS

Mechanic synthesis was originally developed for metallic composite mat erials reinforced by oxide or carbide particles. These preshaped parti cles were incorporated into the powder mix constituting the matrix in the horizontal grinder. Adapted compacting produced a massive material . Recent development in mechanic synthesis concern piloting the direct synthesis of material components during grinding. The elaboration by mechanically activated annealing gives materials with nano-structure b y combination of a short duration mechanic synthesis and a low tempera ture annealing.
