Abstract

An in-situ nanowire Nb/TiNiCu composite is fabricated based on the concept of strain under-matching between a phase transforming matrix and high strength nanomaterials. The deformation behavior of the Nb nanowire was investigated by means of in-situ synchrotron X-ray diffraction when the TiNiCu matrix underwent different deformation modes. The maximum lattice strain of the Nb nanowires was about 5% when the matrix deformed via martensitic transformation or 1% when deforming plastically by dislocation slip. As a result, the Nb nanowires showed a lattice strain of 3.5% when the matrix deformed in the mixed mode of plastic deformation and martensitic transformation, which means that the occurrence of plastic deformation does not impede load transfer from the matrix to the nanowires.

Locality and rapidity of the ultra-large elastic deformation of Nb nanowires in a NiTi phase-transforming matrix

Journal Article Wang, Shan ; Cui, Lishan ; Hao, Shijie ; ... - Scientific Reports

This study investigated the elastic deformation behaviour of Nb nanowires embedded in a NiTi matrix. The Nb nanowires exhibited an ultra-large elastic deformation, which is found to be dictated by the martensitic transformation of the NiTi matrix, thus exhibiting unique characteristics of locality and rapidity. These are in clear contrast to our conventional observation of elastic deformations of crystalline solids, which is a homogeneous lattice distortion with a strain rate controlled by the applied strain. The Nb nanowires are also found to exhibit elastic-plastic deformation accompanying the martensitic transformation of the NiTi matrix in the case when the transformation strainmore »« less

Large elastic strains and ductile necking of W nanowires embedded in TiNi matrix

Journal Article Jiang, Daqiang ; Jia, Zhenghao ; Yang, Hong ; ... - Journal of Materials Science and Technology

The deformation behaviors of W nanowires embedded in a TiNi matrix were investigated by means of in-situ synchrotron high energy X-ray diffraction (HEXRD) and in-situ transmission electron microscopy (TEM) analysis during tensile deformation. The HEXRD measurement indicated that the W nanowires exhibited an average lattice strain of about 1.50 %, whereas the TEM examination revealed a local elastic strain of about 4.59 % in areas adjacent to the TiNi matrix where stress-induced martensitic transformation occurred. This strain corresponds to a stress of ~15 GPa for the W nanowires. In addition, in areas adjacent to the TiNi matrix where plastic deformationmore »« less

Fabrication, microstructure and mechanical properties of W-NiTi composites

Journal Article Shao, Yang ; Guo, Fangmin ; Huan, Yong ; ... - Journal of Alloys and Compounds

Here, new two-phase tungsten-based composites containing 88 wt% tungsten powders and 12 wt% nearly equiatomic NiTi alloy deforming by martensite variant detwinning were fabricated by infiltration and hot pressing in this study. The change of Ti/Ni ratio in NiTi mater alloy and the effect of addition of Nb element on the microstructure, martensitic transformation and mechanical properties of W-NiTi composites were investigated by comparison of W-Ni₅₀Ti₅₀, W-Ni₄₄Ti₅₆, W-Ni₄₂Ti₅₈ and W-Ni₄₂Ti₅₃Nb₅ composites. The results showed that brittle Ni₃Ti formed in the W-Ni₅₀Ti₅₀ and W-Ni₄₄Ti₅₆ composites and brittle Ti₂Ni formed in the W-Ni₄₂Ti₅₈ composites while no brittle intermetallics formed in the W-Ni₄₂Ti₅₃Nb₅more »« less

Tensile properties of a novel W-NiTi heavy alloy with transforming matrix

Journal Article Shao, Yang ; Guo, Fangmin ; Ren, Yang ; ... - Materials Science and Engineering. A, Structural Materials: Properties, Microstructure and Processing

A new class of W-NiTi heavy alloy was prepared by infiltration and vacuum hot pressing. The W-NiTi heavy alloy containing 90 wt% tungsten of particle size 2-8 gm exhibited excellent tensile properties of the tensile strength (1120 MPa) and elongation (7.8%). In situ synchrotron diffraction experiments provided clear evidence on the reorientation of B19'-NiTi martensite at the initial stage of the deformation and the martensitic transformation from B2-NiTi to B19'-NiTi martensite. Finally, the strain hardening of the heavy alloy resulted from the deformation of the martensite phase and the strain hardening of tungsten particles.
