Article Synopsis
- This paper examines the elastic properties of Ti6Al4V alloy in four manufacturing conditions, revealing differences in Young's modulus, shear modulus, and Poisson's ratio.
- A specially designed sample was used to measure sound wave velocities, helping to derive elastic constant tensors and 3D Young's modulus maps, while EBSD and μCT techniques analyzed grain structures and defects.
- Findings indicate that AM materials are less anisotropic than hot rolled alloys; the study emphasizes the importance of manufacturing methods and orientations in material properties for better mechanical design and quality control.
Inorganic nanoparticles of layered [two-dimensional (2D)] compounds with hollow polyhedral structure, known as fullerene-like nanoparticles (IF), were found to have excellent lubricating properties. This behavior can be explained by superposition of three main mechanisms: rolling, sliding, and exfoliation-material transfer (third body). In order to elucidate the tribological mechanism of individual nanoparticles in different regimes, in situ axial nanocompression and shearing forces were applied to individual nanoparticles using a high resolution scanning electron microscope.
