ON THE EFFECT OF PRIOR AUSTENITE GRAIN SIZE ON NEAR-THRESHOLD FATIGUE CRACK GROWTH [PDF]

Scripta Metallurgica, 1977
It is generally accepted that the fatigue or endurance strength of planar slip materials, such as steel and brass, is increased by refining the grain size, whereas in wavy slip materials, such as pure copper and pure aluminum, the fatigue strength is unaffected.

Correlative microscopy for quantification of prior austenite grain size in AF9628 steel

Materials Characterization, 2020
Abstract The characterization of prior austenite grain size is important for an understanding of the microstructure-property relationships in steels. In this study, the prior austenite grain boundaries (PAGBs) were delineated in a low alloy high performance steel, AF9628, with two different methods: (i) conventional approach via etching, followed by ...

Effect of the morphology of the martensite-austenite phase on fracture of the weld heat affected zone in vanadium and niobium microalloyed steels [PDF]

, 2010
In multipass welding, the intercritically reheated coarse grained heat affected zone demonstrates the worst toughness in welded joint, since it contains a high-carbon martensite with some retained austenite, known as M-A phase, which is brittle and ...
