Description	Thermomechanical treatment of alloys from the systems Ni-Ti and Ni-Ti-X represents an important element for modification of transformation behaviour of these materials. Binary alloys are more sensitive to these processes than ternary (quaternary) alloys. For experiments studying influence of thermo-mechanical treatment (thermal cycling under applied stress) the Ni-Ti-Cu-Mo alloy was chosen. The alloys were prepared by melting from elementary metals in high frequency vacuum induction furnace. Melting was performed in graphite crucible, material was cast into graphite mould. In this was a casting was obtained with diameter of 10 mm and height of 300 mm. Afterwards swaging followed and elongation to final form of wire with diameter of approx. 2.3 mm. This was followed by preparation of samples for cycling – wires with length of approx. 260 mm, and by their heat treatment. Various equipment and various number of functional cycles was used. Finally small samples were taken for determination of transformation characteristics by DSC technique and of micro-structural characteristics of selected samples by SEM/TEM methods. The presented paper is focused on investigation of influence of thermal cycling under stress on transformation and microstructural properties of selected Ti-Ni-X alloys.
