Effect of Hot Burnishing Aided by Infrared Radiation on the Modification of Surface and Subsurface of AISI 1045 Steel
(2017-01-01)
The burnishing occurs by plastic deformation by rearranging the excess of material on the surface peaks to its valleys. In order to improve the process, a laser can be used as a heating source to reduce the material yield ...
Correlação entre os resultados de tração a quente e fluência para o cobre comercialmente puro
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, 2011-03-11)
Hot tensile test data were correlated with creep data, in commercially pure copper, using a recently proposed criterion for the analysis of these two kinds of tests at high temperature. The criterion considers the equivalence ...
Hot Formability Of Din 27mncrb5 Steel Sheets Under Controlled Thinning
(ELSEVIER SCIENCE SALAUSANNE, 2016)
Estampagem a quente em escala piloto
(Universidade Federal de Minas GeraisUFMG, 2015-03-26)
In recent years, world efforts in research and development of hot stamped products for application in the automotive industry have been growing. The increasing demands of this industry for reductions in the vehicle weight ...
Characterization and methodology for calculating the mechanical properties of a TRIP-steel submitted to hot stamping and quenching and partitioning (Q&P)
(Lausanne, 2016)
Thermomechanical simulation of quenching, hot stamping, and quenching and partitioning processes of a high-strength TRIP-assisted steel were carried out in a Gleeble®3S50 thermo-mechanical simulator, coupled to the synchrotron ...
Mechanical behavior of carbon fiber/epoxy filament wound laminates exposed to hygrothermal conditioning
(2015-01-01)
This work aims to evaluate the effect of hygrothermal conditioning on the tensile, in-plane shear and viscoelastic properties of carbon fiber/epoxy laminates (fiber volume fraction ≈ 70%). The flat unidirectional laminates ...
