Evolution of Martensitic Microstructure on Carbon Steel Tempered at Low Temperatures
(Elsevier, 2012-01)
This work presents the microstructural changes of a carbon steel during tempering at low temperatures (first stage of tempering), and its effects in the second and third stages. These changes are determined by internal ...
Tempering temperature effects on abrasive wear of mottled cast iron
(ELSEVIER SCIENCE SA, 2009)
The effects of different tempering temperatures (300-600 degrees C) on abrasive wear resistance of mottled cast iron were studied. Abrasive wear tests were carried out using the rubber-wheel test on quartz sand and the pin ...
Characterization of a new Fe-C-Mn-Si-Cr bearing alloy: tempered martensite embrittlement susceptibility
(New York, 2014)
Bearing steels containing 1% C and 1.5% Cr have been the usual material of choice for machine components submitted to rolling and contact fatigue, for more than a century. As a rule these steels are quenched from the ...
Tempering of martensitic 12 percent chromium steels high temperature gas nitrided
(Sao Carlos: UFSCar, 2000, 2014)
Potential effects of climate change on the temperate zones of North and South America

Effect of two drying processes about soybean seed quality
(Chinese Academy of Agricultural Mechanization Sciences, 2017-12)
This work studies the effects of two drying processes on quality soybean seed. This study compares simultaneouslythe effects of two drying processes: the dry-aeration process and conventional drying process. Two drying ...
Levantamento da cinética de revenimento de um aço-carbono ligado ao V, B, Cr, Ni e Mo
(Universidade Federal de Minas GeraisUFMG, 2010-07-01)
The effects of temperature and time on the kinetics of tempering has been evaluated by hardness, tensile and Charpy V-notch tests of specimens quenched and tempered in the range 580 to 680°C. Johnson, Mehl and Avramis ...
