Abstract : At room temperature the stress to deform crystals with edge orientation is higher than the stress to deform crystals with screw orientation. This is probably not on effect due to the blocking of slip lines on the surface by an oxide layer since screw dislocations should find less resistance to penetrate the surface. Aluminum crystals grown in argon atmosphere have a lower critical resolved shear stress than crystals grown in air. (Author)
