Residual Stresses Induced by Dry and Cryogenic Cooling during Machining of AZ31B Magnesium Alloy
TypeArticles dans des revues avec comité de lecture
The major challenge of the Mg alloys has been their unsatisfactory corrosion resistance, which can be enhanced by improving the surface integrity. Cryogenic machining, where liquid nitrogen was used during machining, has been reported to improve the surface integrity of machined components, including compressive residual stresses. This paper analyses the influence of several cutting parameters, tool geometry and cryogenic conditions on the surface and subsurface residual stresses distribution.

Process Mechanics and Surface Integrity Induced by Dry and Cryogenic Machining of AZ31B-O Magnesium Alloy OUTEIRO, José; ROSSI, Frédéric; FROMENTIN, Guillaume; POULACHON, Gérard; GERMAIN, Guénaël; BATISTA, Antonio (Elsevier, 2013)The corrosion resistance of magnesium alloys depends mainly on its surface integrity. Previous experimental studies have shown that machining can induces small (nano-scale) grain size, compressive residual stresses and ...
Residual Stresses in Machining of AISI 52100 Steel under Dry and Cryogenic Conditions: A Brief Summary CARUSO, Serafino; OUTEIRO, José; UMBRELLO, Domenico; BATISTA, Antonio (Trans Tech Publications, 2014)Residual stress is one of the most important surface integrity parameter that can significantly affect the service performance of a mechanical component, such as: contact fatigue, corrosion resistance and part distortion. ...

(Elsevier, 2013)Residual strains induced by drilling of glass-fibre reinforced polymers (GFRP) were determined using a hybrid experimental-numerical methodology. Experimentally, a set of GFRP specimens were drilled under well-defined ...
M'SAOUBI, Rachid; CHANDRASEKARAN, H.; COULON, Bertrand; MARQUES, M.J.; OUTEIRO, José (2008)Machinability enhancement of hot work tool steels can be achieved intrinsically through tailoring of alloying elements and steel processing route but also externally through the use of adequate tooling. The aim of the ...
