Functionally graded NiTi shape memory alloys
Ciência & Tecnologia dos Materiais, 2017Abstract In this study, in order to obtain a functionally graded material, NiTi strips were annealed at 350 °C, 450 °C and 550 °C in a furnace using an assembly that allowed a temperature gradient along them, and their transformation temperatures were studied by Differential Scanning Calorimetry (DSC).

FMR of NiTi alloy single crystals
Journal of Magnetism and Magnetic Materials, 1980Abstract Single crystal samples of NiTi alloys have been examined by FMR. The results are similar to those already reported for NiV in that the g value is temperature dependent and the linewidth is a function of crystal orientation but in the latter case notable differences are observed.

Microstructure of As-cast NiTi alloy
Materials Characterization, 1991Abstract The metallography of as-cast NiTi alloy, of presumably pseudoelastic composition, is described. Characteristic morphologies, obtained in NiTi microstructure, were produced by different solidification conditions. A method is suggested to avoid the formation of primary hard phases during solidification.

Drilling of NiTi Shape Memory Alloys
Materialwissenschaft und Werkstofftechnik, 2004AbstractThe machinability of NiTi based shape memory alloys has been examined by conducting drilling experiments. For this reason the cutting parameters cutting speed and feed were varied within a wide range. The machining process was evaluated in terms of tool wear, cutting forces and machining quality.

Environmental effects in NiTi-based alloys
Scripta Materialia, 1999Environmental embrittlement has been identified as one of the major causes for low ductility and poor fracture toughness in a number of ordered intermetallics containing reactive element,s such as Al, Ti, Si, Mn, V or Mo, when tested in moisture-containing environments at room temperature.

Investigations of endodontic instruments in NiTi superelastic alloy
Metallurgical Science and Tecnology, 1999Endodontic instruments in NiTi alloy, useful in dentistry for restorative procedures, are investigated in terms of functionality, mechanical wear and temperature dependence. The instruments are studied by dynamical mechanical thermal analysis, differential scanning calorimetry, wear tests and scanning electron microscopy.
