The Effects of the Metallic Structures on the Friction and Lubrication in the Cold Deformation Processing of Carbon Steel

摘要

This paper describes the results of a detailed study on the development of surface asperityu27s, under cold compression condition of the pure-iron and carbon-steel which have various grain-sizes.The frictional power occuring between the metal-tool interfaces being directly measured, it is found that the materials of large grain-sizes have greater frictional resistance, and that this phenomenon is most remarkable in the case of the high carbon-steel.
