Abstract

The adiabatic shear stability of unreinforced, unidirectionally reinforced and 3-D braid reinforced aluminum-lithium were studied by static and dynamic blanking at various deformation levels. Comparing to Hadfield steel, no apparent adiabatic shear was detected in any of these materials. The failure mechanism of these structures were identified by microstructural analysis.
