Effect of Microstructure on the Ballistic Performance of Alumina

Abstract

Results of a study of various dense A2O3 bodies using a 22-caliber fragment simulator are presented showing that there is no significant correlation of ballistic performance to static tensile strength, surface finishes, or effect of single crystal orientation. Grain size appears to have a limited effect while there is a definite lowering of performance by some impurities. The effect of impurities depends on their state and thus on method of addition and thermal history. Results are discussed in terms of possible microplasticity. (Author)
