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 ...

工程科学学报, 2018 High-angle grain boundaries and martensite/austenite (M/A) constituents are two critical factors that contribute to low impact toughness in metals. The generation mechanism of the high-angle grain boundaries is closely related to the crystallography of ...

Reconstruction and Size Prediction of Prior Austenite Grain Boundary (PAGB) using Artificial Neural Networks [PDF]
Korean Journal of Metals and Materials, 2020 To automatically reconstruct the prior austenite grains from as-quenched martensitic structure, we applied a deep learning algorithm to recognize the prior austenite grains boundaries hidden in the martensitic matrix. The FC-DenseNet architecture based on FCN (fully convolutional networks) was used to train the martensite and ground truth label of the ...

The role of the austenite grain size in the martensitic transformation in low carbon steels
Materials & Design, 2019 There is sufficient experimental evidence to propose that the formation kinetics of athermal martensite directly depends on the austenite grain structure from which the martensite forms. Yet, this dependence is frequently ignored.
