Abstract: Nitinol (NiTi) alloy consists of nickel (Ni) and titanium (Ti) shows the shape retention and psuedoelasticity while going through phase transformation. NiTi is a strong candidate for engineering applications due to these properties. In this work, NiTi tubes were manufactured via LPBF starting from NiTi powder with (52%Ni-48%Ti). Heat treatment was performed at a continuous temperature of 500 ℃ for 10 min to 60 min. Heat flow analysis shows an increase in austenite finish temperature to 25 ℃. The experiments for thermal expansion coefficient (CTE) shows values of 11.4x10^–6/°C that matached with literature for austenitic thermal expansion coefficient.
