INTERACTION BETWEEN V_4C_3 PARTICLES AND DEFORMATION TWINS

Abstract

Abstract: By using Moire′ pattern formed by the double diffraction of precipitated V_4C_3 and matrix of γ-phase,the nature of the structure of the interface between precipitated V_4C_3 and matrix as well as the retarding effect of V4C3 particles on the development of deformation twins have been investigated.It is shown that partially coherent interfaces exist between V_4C_3 and ma- trix.Twinning dislocations may transform into interfacial dislocations under external stress, and may move continuously through bypassing or cross-sliping.

Key words: V_4C_3, deformation twin, Moire' pattern
