Schematic showing the three-stage deformation mechanism of the additively manufactured Al6061+TiC nanocomposite, which is revealed by in situ neutron diffraction.
Scientific Achievement
Multi-stage anisotropic interphase stress evolution was revealed during deformation of additively manufactured (AMed) TiC-reinforced Al6061 nanocomposites.
Significance and Impact
The understandings of deformation mechanism provide guidance of nanocomposite designs and AM optimizations toward excellent mechanical performance.
Research Details
- Fusion-based AM composited 2%~5% of TiC nanoparticles in Al6061, which increased the strength of the matrix.
- Continuous in situ neutron diffraction captured the dynamic phase-specific behaviors, especially the percentages of TiC.
- TiC refined Al grains, shared load and hindered dislocations movement in Al.
