Determination and Analysis of Residual Stresses Induced by High Speed Milling Using a Micro-indent Method
(Maxwell Science Publication, 2018-06)
The purpose of this work is to determine and analyze residual stress normal components and anisotropy degrees introduced by high-speed milling in specimens of AA 6082-T6 and AA 7075-T6 aluminum alloys. At each machined ...
Microhardness and residual stress of dissimilar and thick aluminum plates AA7181-T7651 and AA7475-T7351 using bobbin, top, bottom, and double-sided FSW methods
(2020-05-12)
Friction stir welding (FSW) is a relatively new manufacturing process (invented in 1991 at the Welding Institute, UK) and more
than 5000 scientific articles have been published in the past 10 years in indexed journals ...
Alívio de tensões residuais em juntas soldadas de caixa espiral de turbina hidraúlica
(Universidade Estadual Paulista (Unesp), 2005-08)
A construção de uma turbina hidráulica consiste, em linhas gerais, de montagem por solda dos vários componentes da estrutura. As tensões residuais em junta soldada são de natureza complexa envolvendo fenômenos mecânicos e ...

Estudo da tensão residual através de difração de raios X em aço inoxidável duplex submetido a diferentes tratamentos térmicos
(Universidade Federal do Espírito SantoBRMateriais e Processos de Fabricação; Mecânica dos SólidosPrograma de Pós-Graduação em Engenharia MecânicaUFES, 2012-12-07)
The evolution of residual stresses in a duplex stainless steel with different thermal treatments was investigated by X-ray diffraction. In this work, samples of steel UNS S32304 were analyzed. These materials have a two-phase ...
Analysis of Residual Stresses in High Speed Milled Aluminum Alloys
(Maxwell Science Publication, 2017-03)
The purpose of this study is to evaluate, from high speed machining tests, the behavior of the residual stresses induced in samples of AA 6082-T6 and AA 7075-T6 aluminum alloys. This study includes an exhaustive analysis ...
Evaluation of grinding fluids in the grinding of a martensitic valve steel with CBN and alumina abrasives
(Professional Engineering Publishing Ltd, 2003-01-01)
In this paper the performances of different cutting fluids and grinding wheel types were analysed in the grinding of SAE HVN-3 workpieces. The resulting residual stress, wheel wear and roughness were evaluated. The influence ...
