Lamellar eutectic growth with anisotropic interphase boundaries

We present a numerical study of the effect of a free-energy anisotropy of the solidsolid interphase boundaries on the formation of tilted lamellar microstructures during directional solidification of nonfaceted binary eutectic alloys. We used two different methods – phase-field (PF) and dynamic boundary-integral (BI) – to simulate the growth of periodic eutectic patterns in two dimensions. For ...

On the structure of grain/interphase boundaries and interfaces

Grain/interphase boundaries/interfaces of varying misorientations, free volume fractions, curvatures and irregularities are present in materials, both 3D and 2D, regardless of whether these materials are crystalline or amorphous/glassy. Therefore, a question arises about the central idea on which a general description of grain/interphase boundaries/interfaces can and should be based. It is sugg...

Eleventh International Conference on Intergranular and Interphase Boundaries 2004

We analyze recent results of atomistic computer simulations of grain boundary (GB) diffusion in metals. At temperatures well below the bulk melting point Tm GB diffusion occurs by random walk of individual vacancies and self-interstitials. Both defects are equal participants in the diffusion process and can move by a large variety of diffusion mechanisms, many of which are collective transition...

Mobility of Interphase Boundaries and Hysteresis of Martensitic Transformation in Alloys

A phenomenological description of martensitic transformation is proposed on the basis of such parameters as: a degree of lattice coherency between austenite and martensite phases, mobility of interphase boundaries, elastic energy stored during martensitic transformation and degree of its relaxation. Son),: experimental results confirming the proposed ideas are presented.

FORMATION OF THE (γ/α) - INTERPHASE BOUNDARIES IN FeCrNi ALLOYS BY A DIFFUSION BONDING METHOD

Characteristics of the interphase boundary in two-phase (y/a)-stainless steel couples produced by a solid-solid diffusion method,starting from Fe-30%Cr(aphase) and Fe-15ZCr-15%Ni(y-phase) alloys, have been described. Interphase boundaries between a parent y-phase and a transformed a-phase have been found to be essentially planar and no special structual defects have been detected, excepting a s...
