Nanotribological behavior of deep cryogenically treated martensitic stainless steel
(Beilstein-Institut, 2017-08)
Cryogenic treatments are increasingly used to improve the wear resistance of various steel alloys by means of transformation of retained austenite, deformation of virgin martensite and carbide refinement. In this work the ...
Effects of cryogenic and stress relief treatments on temper carbide precipitation in AISI D2 tool steel
(Redditch, 2013-11-14)
The effects of cryogenic and stress relief treatments on temper carbide precipitation in the cold work tool steel AISI D2 were studied. For the cryogenic treatment the temperature was −196°C and the holding time was 2, 24 ...
Influence of Cryogenic Treatments on the Wear Behavior of AISI 420 Martensitic Stainless Steel
(Springer, 2017-11)
The objective of the present work is to characterize the wear behavior of a cryogenically treated low-carbon AISI 420 martensitic stainless steel, by means of ball-on-disk tribological tests. Wear tests were performed under ...
Microestrutura e propriedades mecânicas da liga AA6061 processada por deformação plástica severa em temperatura criogênica
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2017-08-08)
The present work aimed two fronts: to characterize the mechanical behavior of the AA6061 alloy at cryogenic temperature, and to study the microstructural and properties evolution after cryogenic severe plastic deformation. ...
Dynamic modelling and optimisation of cryogenic systems
(Pergamon-Elsevier Science Ltd, 2007-05)
This work addresses the dynamic optimisation of the cryogenic sector in a large-scale natural gas processing plant. Main attention is focused on rigorous dynamic modelling of countercurrent heat exchangers with phase change ...
