摘要: Nanostructures were formed in several conventional materials under single electropulsing, that is nanophases of alpha-Cu(Zn) and beta'-(CuZn) a cold-worked alloy, nanosized gamma-Fe low-carbon steel, alpha-Al superduralumin, orientated TiC TiC/NiCr cermet. The mechanisms responsible for the above nanostructured transitions can be attributed to competition many factors induced by including high-rate heating, thermal stress, reduced thermodynamic energy barrier electron impacting. Also, low-energy dislocation configurations, twins stacking faults copper alloy cermet electropulsing. Such evolution defects was associated with electrical, stress energies (C) 2003 Elsevier Ltd.
