dc.description.abstractPurposeThis study aims to investigate NiTi alloys' characterization and corrosion behaviour produced by two different powder metallurgy (PM) methods. Design/methodology/approachIt was pre-formed under a protective atmosphere at 900 & DEG;C under a force of 45 MPa and sintered for 1 h under 10-6 Mbar in an atmosphere-controlled heat treatment furnace at 1,100 & DEG;C. The relationship between microstructural properties, SEM, XRD, density, microhardness and corrosion behaviour of pre-alloyed NiTi alloys produced by two different methods with the production method was investigated. FindingsAs a result of the studies, TiO, NiTi, NiTi2 and Ni3Ti intermetallics were determined in XRD examinations. The best surface roughness was observed in the mechanically milled (MM'ed) pre-alloyed NiTi alloy compared to the pre-alloyed NiTi alloy mixed with turbula. The corrosion tests performed in 3.5% NaCl solution determined that the MM'ed pre-alloyed NiTi alloy had better corrosion resistance than the pre-alloyed NiTi alloy mixed with turbula. Pitting corrosion was visualized in the SEM images taken from the corrosion surfaces. Originality/valueTwo different PM methods produced pre-alloyed NiTi powders, and the effects of these methods on the mechanical and corrosion resistance of NiTi alloys were systematically investigated for the first time.en_US
