-Integral Testing of Aluminum Alloys: A New Technique for Marking Crack Fronts

CODEN: JTEVAB

Abstract

An important aspect of the standardized JIc test method is the measurement of the amount of crack extension as a function of load. The usual method of marking crack fronts for subsequent measurement in a luminum alloys is to fatigue cycle after initial static crack extension.

In this paper, a new technique for marking crack fronts in aluminum alloys is described. This new technique, based on liquid metal embrittlement of grain boundaries in aluminum by gallium, is, for the alloys examined in this work, a more effective method of crack front marking than fatigue cycling.
