文摘
- •
Dislocation transmutation reactions by (10–12) twinning were confirmed in TEM.
- •
The transmutation concept is a source mechanism, producing only <c ± a2> among all six possible <c + a> dislocations.
- •
The interfacial reaction products could result in a dragging effect on twin boundary advancement.
- •
The transmuted <c + a> dislocations inside twin establish a basis for subsequent rapid hardening.
