Niti and NiTi-TiC composites: Part III. shape-memory recovery
Metallurgical and Materials Transactions A, 1996The transformation behavior of near-equiatomic NiTi containing 0, 10, and 20 vol pct TiC particulates is investigated by dilatometry. Undeformed composites exhibit a macroscopic transformation strain larger than predicted when assuming that the elastic transformation mismatch between the matrix and the particulates is unrelaxed, indicating that the ...

Structure of incommensurate NiTi(Fe)
Physical Review B, 1989NiTi(Fe) has an incommensurate and a commensurate phase between its low-temperature martensitic and high-temperature CsCl-type structures. Anomalous deviations of the satellite positions in the incommensurate phase have been reported. These deviations have raised doubts about the adequacy of a model based on sinusoidal modulations of the basic ...

Tensile deformation of NiTi wires
Journal of Biomedical Materials Research Part A, 2005AbstractWe examine the structure and properties of cold drawn Ti‐50.1 at % Ni and Ti‐50.9 at % Ni shape memory alloy wires. Wires with both compositions possess a strong <111> fiber texture in the wire drawing direction, a grain size on the order of micrometers, and a high dislocation density.

The purpose of this study is to build a fundamental understanding of the relationship between the structure and properties of cast nickel‐titanium (NiTi). The structure of the cast material will be analyzed at various scales and will be related to the properties of the cast material such as transformation temperatures, stress‐strain behavior, and ...

Niti and NiTi-TiC composites: Part II. compressive mechanical properties
Metallurgical and Materials Transactions A, 1996The deformation behavior under uniaxial compression of NiTi containing 0, 10, and 20 vol pct TiC participates is investigated both below and above the matrix martensitic transformation temperature: (1) at room temperature, where the martensitic matrix deforms plastically by slip and/or twinning; and (2) at elevated temperature, where plastic ...

Journal of Materials Science, 1999
Lattice defects are introduced into stable austenite (β) by hot rolling up to 70% (in one pass) in a temperature range between 900 > TAF > 340 °C (ausforming (AF)). The changes in microstructure, thermal transformation behavior, as well as normal and anomalous properties in stress-, strain-, and temperature-space were studied.

Laser spray cladding of porous NiTi coatings on NiTi substrates
Surface and Coatings Technology, 2007Abstract Laser spray cladding in N 2 -rich atmosphere is a competitive technique for manufacture of porous NiTi shape memory alloy (SMA) and TiN surface film. In order to gain expected porous coating and porosity size, TiH 2 powder was considered to be used as porosity initiating agent, and nitrogen was used for shielding and active nitriding gas ...

Microstructure and Strength of NiTi-Nb Eutectic Braze Joining NiTi Wires
Metallurgical and Materials Transactions A, 2015NiTi wires were brazed together via liquid eutectic formation between NiTi and Nb powders deposited at the wire contact region. The brazed region shows proeutectic NiTi(Nb) in contact with the wires, sandwiching a NiTi-Nb eutectic structure, whose microhardness and stiffness, as characterized via nanoindentation, are higher than the NiTi wires, while ...

Fatigue crack-growth in shape-memory NiTi and NiTi–TiC composites
Materials Science and Engineering: A, 2000Abstract An experimental study was conducted to examine the room-temperature fatigue crack-growth characteristics of shape-memory NiTi matrix composites reinforced with 10 and 20 vol.% of TiC particles. Microstructural characterization of these hot-isostatically-pressed materials shows that the TiC particles do not react with the NiTi matrix and that
