Question

Problem 9.4 A Single crystal of aluminum (b =0.286 nm) was tested in uniaxial tension with its most favorable slip planes oriented at 45 degrees relative to the tensile axis. Testing was interrupted at an early stage and inspection at high magnification indicated the presence of slip traces on the specimen surface with average depth of 500 nm and average spacing of 100micrometer A. on average, how many dislocations must have emerged from the crystal at each observable slip trace? B. Find the shear Strain on the slip system, calculated over the whole crystal.
