Avaliação na zona termicamente afetada de um aço inoxidável supermartensítico
(Universidade Federal de Minas GeraisUFMG, 2010-04-29)
Nowadays, there is a strong trend for exploiting oil and gas in places that demand a high level of operation complexity. There are, for example, the presence of high levels of contaminants (mainly carbon dioxide, CO2, and ...
Caracterização da interface de tubo bimetálico cladeado fundido por centrifugação
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2015-03-27)
Bimetallic pipes represent a solution for cost reduction to pipelines in the oil and
gas industry, because they combine two materials with distinct characteristics in
the pipe manufacturing: a HSLA steel, constituting ...
