Abstract
Bending and uniaxial tensile tests for Al-base amorphous ribbons were perfo rmed at room temperature for a number of compositions, Al-nanocrystal preci pitation was observed within vein protrusions on fracture surfaces and alon g crack propagation paths. as well as within shear bands resulting from ben ding. A composition dependence of crystallization upon bending was also obs erved. Effects of local adiabatic heating was observed on fracture surface.
