Purpose: The main aim of the work is to investigate the effect of deformation sequence of low cyclic torsion, monotonic torsion and monotonic tension on the flow stress and structure. This knowledge can create possibility to elaborating and applying more energy and material saving technologies where final products have determined shape and properties. Design/methodology/approach: Simultaneous deformation by cyclic torsion and tension was conducted in plastometer for complex strain paths. For micro structural observation, the optical, scanning and transition microscopes were used. Findings: Obtained results shown that by change of direction of displacement velocity vector for about 90° it is possible to increase or decrease of the flow stress. Without such changes of this vector the dislocation structure is not enough disturbed and strain localization in shear bands is absent, so there is no softening of materials caused by increase of free distance of dislocation movement. Research limitations/implications: The further investigations should be done especially at high temperature because at high temperature the investigated silicon bronze has large strain rate sensitivity that make difficulties to transform torque on the shear stress moreover the precise stabilization of temperature at high temperature is difficult. Practical implications: On the base of performed investigation it can be stated that great progress in metal forming processes and new technologies, more effective from the point of view of energy and material consumption could be elaborated. Originality/value: The effect of strain path in case of sheet metals forming processes has been investigated for a long time. In case of massive processes the effect of strain path on the plastic properties and structure of materials is less known because an investigations are more difficult and complex.
