Abstract:

This investigation indicates that the fibre fracture test applied to face hardened armor will probably enable prediction as to whether or not the plate will resist cracking under projectile impact. Furthermore, the steel soundness may be ascertained and the approximate case depth can be determined. The total depth of the carburized case as revealed by the fracture test coincides fairly well with the depth of the case as determined by macroscopic and microscopic examination and by the analysis of the carbon distribution in the case. The Vickers Brinell hardness survey indicated the depth of the effective case.
