ME 3701 Chapter : Crystal Structure Analysis In Engineering Materials Lab 1
Document Summary
Crystal structure analysis in engineering materials: briefly explain the differences between [1 1 1], (1 1 1), <1 1 1>, and {1 1 1}. Annealed stainless steel) is provided in ascii format. Load each file into a spreadsheet and plot the intensity of the diffracted beams (cps) versus the diffraction angle 2 (degrees) for each sample. The plots should be similar to that presented in figure 5. Examine each of the plots noting how the diffraction lines appear. Graph 1 sample 1 fcc aluminum. Sample 1 s p c y t i s n e t n. Graph 2 sample 2 bcc stainless steal. Sample 2 s p c y t i s n e t n. Angle(degrees: assuming first order diffraction, determine an expression for the diffraction angle ( ) as a function of wavelength ( ), the lattice parameter (a), and the miller indices (h,k,l) based on equations (2) and (3); then:
