Item The effect of lattice vacancies on the elastic modulus(1958) Folweiler, Robert Cooper; Brotzen, Franz R.The effect of quenched-in vacancies upon the elastic modulus of aluminum ma investigated. Equipment for dynamically measuring the change in elastic modulus was developed for the purpose. It was demonstrated that the presence of lattice vacancies will reduce the elastic modulus. This change in elastic modulus was investigated as a function of the number of vacancies and the annealing of vacancies at room temperature. A comparison is made with theoretically derived results.
