Computer Techniques Towards the Automatic Characterization of Graphite Particle...
João P. Papa; Rodrigo Y. M. Nakamura; Victor Hugo C. de Albuquerque; Alexandre X. Falcão; João Manuel R. S. TavaresThe automatic characterization of particles in metallographic images has been paramount, mainly because of the importance of quantifying such microstructures in order to assess the mechanical properties of materials common used in industry. This automated characterization may avoid problems related with fatigue and possible measurement errors. In this paper, computer techniques are used and assessed towards the...
Automatic Segmentation of the Secondary Austenite-phase Island Precipitates in ...
Victor H. C. Albuquerque; Rodrigo Y. M. Nakamura; João P. Papa; Cleiton C. Silva; João Manuel R. S.TavaresDuplex and superduplex stainless steels are class of materials of a high importance for engineering purposes, since they have good mechanical properties combination and also are very resistant to corrosion. It is known as well that the chemical composition of such steels is very important to maintain some desired properties. In the past years, some works have reported that gama 2 precipitation improves the toug...
