Microstructural effects on fatigue crack growth behavior of a microalloyed steel
(2010-04-01)
Thermal transformations on microalloyed steels can produce multiphase microstructures with different amounts of ferrite, martensite, bainite and retained austenite. These different phases, with distinct morphologies, are ...
