Characterization and boriding kinetics of C38 carbon steel: effect of the process time
Matériaux & Techniques, 2012 This present work investigates the effect of the time duration on the boriding kinetics of C38 steel. The pack-boriding treatment was carried out at 1000 °C for 0.5, 1, 2, 4 and 8 h using a powdery mixture consisting of 5%B4 C, 5%NaBF4 and 90% SiC.

ECS Transactions, 2015 The use of Xylopia frutescens extract as a C38 steel corrosion inhibitor in 1 M HCl solution was investigated by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) methods. Potentiodynamic polarization curves indicated that Xylopia frutescens extract behaves as mixed-type inhibitor.

Tensile Behavior of Semi-Solid C38 LTT Steel
Solid State Phenomena, 2016The high temperature range for steel semi-solid state makes the experiments particularly challenging. While the response under shear or compression loadings was studied, few results concerned the response under tensile loading. In this paper, an experimental protocol was determined to characterize the uniaxial tensile response of the so-called C38 LTT ...

Kinetic investigation of C38 steel corrosion in concentrated perchloric acid solutions
Materials Chemistry and Physics, 2010The corrosion behaviour of steel at various concentrations of perchloric acid was studied by weight loss method in temperature range from 298 to 323 K. Results obtained show that corrosiveness of acid increases with its concentration and temperature. The logarithm of corrosion rate was plotted against the acid concentration and values of Hammett Ho and
