AB  - In this study, the effects of Zr addition on phase transformation temperatures, microstructure of Ti-12V-4Al (wt. %) high temperature shape memory alloys (HTSMAs) manufactured using melt-spinning technique were investigated. During heating, differential scanning calorimetry (DSC) curves showed that austenite transformation temperature of Ti-12V-4Al (wt. %) melt-spun ribbon was single-stage transformation and Ti-12V-4Al-0.5Zr (wt. %) melt-spun ribbon was two-stage transformation.  In the scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyzes, unveiled that the melt-spun ribbons consisted of martensite, austenite and R phases. Transmission electron microscopy (TEM) analysis showed that the thickness of martensite plates in ribbons was thinned by the addition of Zr.
