Friction spot joining of aluminum alloy 2024-t3 and carbon-fiber-reinforced polyphenylene sulfide composite laminate with additional pps film interlayer
(Universidade Federal de São Carlos, 2015-11-30)
Friction Spot Joining (FSpJ) is a prize-winning joining technique for hybrid
metal-polymer composite structures. This master thesis was devised to
investigate the feasibility of FSpJ of metal-composite structures with ...
Efeito do envelhecimento em baixa temperatura nas propriedades de aços inoxidáveis lean duplex
(Universidade Federal de São Carlos, 2016-03-23)
In this work, the mechanical and corrosion properties of two lean duplex steels
(LDSS) 2101 and 2404 aged at 475 °C for up to 2000 h were assessed, and the
obtained results were compared with the standard duplex stainless ...
Investigação microestrutural e estudo das propriedades mecânicas da liga de alumínio AA2139 T3 e T8 soldadas por Friction Stir Welding - FSW
(Universidade Federal de São Carlos, 2011-02-17)
