Two-Way Shape Memory Effect in Rapidly Quenched Highly Doped Alloys of TiNi–TiCu System upon Laser Treatment

Amorphous-Nanocrystalline Composites Prepared by High-Pressure Torsion

“…Heat treatment of AA at controlled temperature and time parameters initiates the nucleation and growth of nanocrystals, i.e., the formation of a composite material with an amorphous matrix [17][18][19]. It is possible to modify the AA surface by laser for the manufacture of "sandwich" amorphous-nanocrystalline composites and gradient structures with amorphous-nanocrystalline components [20][21][22]. The composite consisting Metals 2020, 10, 511 2 of 19 of an amorphous phase with a nanocrystalline filler can surpass fully amorphous or fully crystalline analogs in the combination of properties [23][24][25][26].…”

“…In the framework of the present work, the idea arose to use the possibilities of severe plastic deformation (SPD) in a Bridgman chamber for the preparation of layered amorphous-nanocrystalline composites. We used two fundamentally different methodological techniques ( Figure 1 components [20][21][22]. The composite consisting of an amorphous phase with a nanocrystalline filler can surpass fully amorphous or fully crystalline analogs in the combination of properties [23][24][25][26].…”
