(a) Schematic representation of the geometry of the simulation domain showing cylindrical intenders applied at top and bottom surfaces. (b) Instantaneous hydrostatic stress field within an -cross section of the simulation domain. Dark shade represents compression while light shade denotes tension.
(a) Patterning extent as a function of total identity switch attempts: (i) , (ii) , (iii) , and (iv) nonisothermal anneal with . (b) Phase diagram for binary LJ alloy with parameters defined in Table I. Dashed (isothermal) and solid (variable temperature) path lines represent corresponding compositional evolution pathway of the matrix phase away from the indenters.
Morphological evolution as a function of total switch attempts for two annealing processes of an initially homogenous solid solution. atoms are black and atoms light gray. Left side: isothermal anneal at . Right side: variable temperature anneal . From top to bottom, the images on each row are taken at: 0 , , , , , , and switch attempts, respectively. The quoted temperatures correspond to the variable temperature anneal.
Length and energy scale parameters for the LJ potential.
