MACROSCOPIC MODELING OF 2-PHASE METAL MATERIALS

Microscopic phenomena of the deformation of two-phase metal materials, material flow, formation and propagation of cracks, motion of broken particles of the secondary phase in the matrix or of the matrix-flow i n situ are very difficult to be traced. The solution of that problem i s presented by macroscopic models enlarged for few orders of magnitude in comparison to the microstructure of real materials. Properties of the single model components are relatively very well comparable to tho se of the real materials. Two types of models have been made: the firs t one considered by the tensile deformation, and the second one by mor e complex way of the rolling deformation.
