AUTO-SHAPE ANALYSIS OF IMAGE TEXTURES IN FRACTOGRAPHY
Image Analysis and Stereology, 2011 The aim of this study is to estimate the velocity of fatigue crack growth (crack growth rate - CGR) from the texture in SEM images of crack surfaces. A simple and quick method is based on fitting training images as a linear combination of several small ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Fe‐Cr‐Ni‐Cu alloy has been extensively utilized over the past few decades due to its low cost yet high strength. Nevertheless, the poor ductility of this alloy limits its real application in industrial fields. In this study, a soft Fe‐Cr‐Ni alloy was combined with a Fe‐Cr‐Ni‐Cu alloy by laser‐directed energy deposition (LDED) to fabricate the ...
