Experiment 1: Crystal Structure: X - Ray Diffraction
The X-Ray diffraction technique is used to determine the crystal structure and interatomic spacing of crystallinesamples through constructive interference of reflected x-ray beams.
Bragg's Law and X-Ray diffraction data, in combination with the expressions for interatomic spacing in terms of the lattice parameter and Miller indices for acrystal, can be utilized to identify crystal structures, determine lattice constants, and locate defects within astructure.
materials of engineering laboratory
In the spring semester of 2002, Dr. Woldesenbet and I gave a hand-on laboratory course: Materials of Engineering Laboratory, to the junior undergraduate students at the Louisiana State University. In this Blog, I am also adding some state-of-the-art techniques for materials laboratory.

Movie of an expanding ring experiment
I have posted a movie showing a ring expansion experiment. A thin aluminum ring is made to expand through electromagnetic interaction at strain rates of about 10^4 per second. As the strain increases, numerous necks and fragments appear.
