An Evaluation of the Plane Strain Compression Test. III. Experimental Study of the Friction Test: The Role of the Metallurgical Parameters of Die and Sheet

This paper deals with the influence of the metallurgical parameters of dies and sheet on the friction shear-stress which could be measured by P.S.C.T. The metallurgical parameters of the dies have a marked effect on the kinetics of formation of transfer layers. The metallurgical parameters of the sheet have an effect both on the kinetics of formation, and the chemical nature of the transfer layers. Many parameters must be controlled to have good reliability in PSCT. Then the results can be correlated with boundary lubrication in cold rolling.
