Abstract:

The investigation of the mechanical properties of ceramics as related to their electronic structure is continued. The optical-mechanical properties of germanium have been studied and experimental results are presented for internal friction and bending tests conducted in the presence of infrared irradiation. The cleavage energy of sodium chloride is given as a function of F-center density and testing environment. The cleavage energy of sodium chloride colored by diffusion increases by two at a density of 10 to the 16th power F-centerscc, with no apparent increase in the elastic modulus. Experimental results are given for Hall coefficient measurements on beryllium. Author
