Popis:	The effect of a tensile stress during electric pulse heat treatment on crystal structure formation in amorphous rapidly hardened Ti50Ni25Cu25 alloys is studied. Amorphous ribbons are subjected to a 10-msec electric pulse treatment in a free condition and under a tensile stress of 5.9 and 29.7 MPa. Specimen structure is studied by optical and scanning electron microscopy, energy dispersive analysis, and differential scanning calorimetry. It is shown that amorphous ribbon crystallization under electric pulse treatment with a tensile load occurs primarily due to growth of surface columnar crystals from the ribbon surface into the depth and then from the internal part of a ribbon due to spherulite formation and growth.
