    The purpose of this paper is to promote consideration of variable amplitude or spectrum fatigue loading as a useful tool for screening effects of alloy microstructure on fatigue crack-propagation resistance. Increased sensitivity to microstructure, practical interpretation, and economy of testing are offered as rationale for advantageous use of this type of test.
