Pulsed Nd:YAG laser welding of AISI 304 to AISI 420 stainless steels
José Roberto Berretta,Wagner de Rossi,Maurício David Martins das Neves,Ivan Alves de Almeida,Nilson D. Vieira Junior +4 more
TL;DR: In this paper, the influence of the laser beam position, with respect to the joint, on weld characteristics was investigated, and the results of various tests and examinations enabled definition of the best position for the incident laser beam with respect on the joint for welding together the two stainless steels.
Journal ArticleDOI
Microstructure development in Nd:YAG laser welding of AISI 304 and Inconel 600
Maurício David Martins das Neves,André Lotto,José Roberto Berretta,Wagner de Rossi,Nilson D. Vieira Junior +4 more
TL;DR: In this article, the morphology of the weld zone (WZ) was studied in a joint formed from dissimilar materials, composed of austenitic AISI 304 stainless steel and Inconel 600 nickel alloy, welded with an Nd:YAG-pulsed laser.
Book ChapterDOI
Perspective of Additive Manufacturing Selective Laser Melting in Co-Cr-Mo Alloy in the Consolidation of Dental Prosthesis
TL;DR: In this paper, the authors compared the properties of additive manufacturing (AM) by the selective laser melting (SLM) technology and compare with the precision casting (PC) processes using the Co-Cr-Mo (ASTM F75) alloy to manufacture of dental prosthesis.
Journal ArticleDOI
Localized corrosion of laser marked M340 martensitic stainless steel for biomedical applications studied by the scanning vibrating electrode technique under polarization
Sara M. Manhabosco,Álvaro Pritzel dos Santos,Marcelo L. Marcolin,Eurico F. Pieretti,Maurício David Martins das Neves,Luis Frederico Pinheiro Dick +5 more
TL;DR: In this paper, the authors used the scanning vibrating electrode technique (SVET) under simultaneous polarization and cyclic voltammetry in a 0.1 M NaCl solution.
Journal ArticleDOI
Influence of the heat treatment on the microstructure of AISI T15 high speed steel
Rejane A. Nogueira,Odília C.S. Ribeiro,Maurício David Martins das Neves,Luis Filipe C.P. de Lima,Francisco Ambrozio Filho,Delmonte N. Friedrich,Lourival Boehs +6 more
TL;DR: In this article, the influence of quenching temperature on the mean austenite grain size and size distribution and volume fraction of the primary carbides, MC and M 6 C, in AISI T15 samples prepared by hot isostatic pressing and liquid phase vacuum sintering was quantitatively investigated.
