Thermomechanical Modelling and Simulation of C38 Thixoextrusion Steel [PDF]

Solid State Phenomena, 2014
The present paper focuses the modelling and the simulation of a direct thixoextrusion test achieved on C38 semi-solid steel. Many parameters related to thermal, mechanical, material features are involved but are currently unknown. Consequently to validate the modelling and the simulation, it is important to get various experimental informations during ...

Carob seed oil: an efficient inhibitor of C38 steel corrosion in hydrochloric acid [PDF]

International Journal of Industrial Chemistry, 2012
AbstractBackgroundThe carob seed oil (CO) was tested as inhibitor of the corrosion of C38 steel in 1 M HCl by weight loss and electrochemical measurements. The extract was found to inhibit the corrosion of C38 steel in 1 M HCl.ResultsThe results of the study reveal that the inhibition efficiency of CO depends on its concentration and attains ...
