Abstract     Two-phase metal materials are an important family of materials. In our work a combined experimental and numerical (Finjite Element-FE) stress-strain analysis of two-phase alloys has been performed. Two-phase material model consists of a matrix and second phase inclusions. The matrices are materials with low yield strength, hardness and Young's modelus (ZnCuTi and SnPbSb alloy) and of a high ductility and toughness. Cylindrical inclusions were from low carbon and high speed steels with relatively high mechanical properties. models have been plastic deformed with tensile loading and rolling. Specimens were investigated by X-ray diffraction, dimensional measurements and by measurements of microhardness. The plastic deformation of the matrices around cyndrical inserts was observed by X-ray and neutron radiography. The mechanical deformations were measured by profilometric analysis of neutron radiographs. The deformation processes were simulated with finite element analysis (FEA). The parameters observed and discussed are stresses and strains in metal matrix, the inserts and in the interface.
