Abstract

Bending and uniaxial tensile tests for Al-base amorphous ribbons were performed at room temperature for a number of compositions. Al-nanocrystal precipitation was observed within vein protrusions on fracture surfaces and along crack propagation paths, as well as within shear bands resulting from bending. A composition dependence of crystallization upon bending was also observed. Effects of local adiabatic heating was observed on fracture surface.
