(Elsevier Science SALausanne, 2016)
Microstructural and Residuals Stress Analysis of Friction Stir Welding of X80 Pipeline Steel Plates Using Magnetic Barkhausen Noise
(2019-12-01)
Friction stir welding is a solid-state joining method conducted under large stress and strain conditions at low peak temperatures when compared to arc welding. Friction stir welding produces a large variety of microstructures ...
STUDY OF AGITATION, COLOR AND STRESS LIGHT VARIABLES ON Spirulina platensis CULTURE IN A VERTICAL STIRRED REACTOR IN STANDARD MEDIUM
(Univ Autonoma Metropolitana-iztapalapa, 2020-01-01)
Spirulina platensis is a helical-shaped photosynthetic cyanobacterium. Its cultivation depends on light intensity, nutrients, pH, cell density, temperature, among others. Microalgae are capable of growing in open and closed ...
Corrosion Behavior and Microstructural Characterization of Friction Stir Welded API X70 Steel
(2021-01-01)
Friction stir welding (FSW) is an excellent alternative process used in pipelines circumferential welds due to fusion welded joint low corrosion resistance. This study describes the corrosion resistance as a function of ...
Análise numérico-experimental da agitação de calda em reservatórios de pulverizadores agrícolas
(2015-01-01)
This paper presents a numerical and experimental study of spray fluid performance with stirring in tanks of agricultural sprayers. The pesticide spray should be stirred properly to ensure spraying homogeneity throughout ...
Modeling of thermal cycles and microstructural analysis of pipeline steels processed by friction stir processing
(2018-10-01)
During friction stir welding or processing (FSP), temperature and deformation have influence on the final microstructure and mechanical properties. Studying microstructures before and after welding might help interpreting ...
Tool geometry optimization in friction stir spot welding of Al-steel joints
(Elsevier, 2017-04)
The necessity to reduce the weight of transport structures, such as cars and airplanes, has become more important due to gas emission regulations. In this regard, the use of hybrid structures made of steel and aluminum is ...
