Transition Velocity Experiments on Ceramics

Abstract

ARL has awarded FOI a contract to assess the transition velocities of four silicon carbide (SiC) materials of potential interest for armor applications using a test method developed at FOI. These materials are produced by Cercom Inc. and have the designations SiC B, SiC N, Sic HPN and SiC-SC-lRN. FOI has fabricated the targets and carried out the tests required under the contract to supplement tests performed earlier at FOI. In this report, all primary data are accounted for and the penetration and erosion velocities are evaluated. The transition velocity intervals are obtained to within 50 m/s or better, enabling a ranking of the materials. SiC HPN has the highest transition velocity, above 1600 m/s, while the other materials have a transition velocity just above 1500 m/s. The transition from interface defeat to penetration is distinct and the complicated penetration behavior above the transition velocity is discussed. Suggestions for possible additional work are presented.
