Title: Achieving ultra-high bearing strength of tungsten nanoribbons in a transforming metal matrix

Abstract

Nanowires (or nanoribbons) were identified as the most potential structural reinforcements for composites due to their ultrahigh strength, but it is difficult to transcribe their ultrahigh strength into the composite. Here, an in-situ W nanoribbbons-NiTi matrix composite was fabricated by mechanical reduction of a W-NiTi ingot, and the micromechanical deformation behavior was studied by in-situ high energy X-ray diffraction during tensile loading-unloading. It is revealed that the large elastic deformation of the W nanoribbons in a NiTi matrix is dictated by and synchronized with the martensitic transformation of the matrix. The bearing strength of the W nanoribbons, up to 11.6 GPa, was achieved in this composite. A significant load transfer took place from the matrix to the nanoribbons, exhibiting the characters of locality and rapidity. In conclusion, the stress fraction carried by the W nanoribbons with the volume fraction of 3% is up to 45% for the strength of the composite.
