Gas Washing of Fracture Surfaces by Explosive Detonation Products

Abstract

Experiments have been carried out to study the nature of features produced on fracture surfaces after washing with the gaseous products of detonation of a high explosive. White-etching, essentially untempered martensite layers are produced. A porous outer layer indicative of melting may form, masking features of the original fracture surface. It is concluded that most fragments from a detonated body are ejected before these effects can occur.
