Influência da forma de contato inicial e preaquecimento na camada intermetálica no processo de soldagem por fricção de materiais dissimilares
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA MECÂNICAPrograma de Pós-Graduação em Engenharia MecanicaUFMG, 2021-03-26)
Friction welding is a solid-state welding process and has as its main joining mechanism, diffusion and mechanical mixing. The process is presented as an option, as it generates less residual stress, less distortion and ...
Genetic divergence in Eucalyptus spp. clones by molecular RAPD markers
(2006-09-01)
The genetic divergence in 20 Eucalyptus spp. clones was evaluated by multivariate techniques based on 167 RAPD markers, of which 155 were polymorphic and 12 monomorphic. The measures of genetic distances were obtained by ...

Residual stresses in similar and dissimilar friction stir welds of AA5083 and AA6061
(Trans Tech Publications, 2019-07)
Similar and dissimilar friction stir welds of AA5083 and AA6061 were produced modifying the location of the materials in the joint (advancing or retreating side) and travel speed (73 and 206 mm/min). Longitudinal and ...
