The Bauschinger Effect in Carbon Steels

Abstract

The Bauschinger effect in carbon steels having various structures is studied experimentally. First, the characteristics of the Bauschinger effect in carbon steel are studied and the quantitative description of the Bauschinger effect is made. And then, using this description, the relations between the Bauschinger effect and the prestrain and the structure, the anisotropy of the Bauschinger effect and the process of the removal of the Bauschinger effect by ageing are investigated. In conclusion, the Bauschinger effect in carbon steels is largely attributed to the unevenness of the microscopic internal stress and strain produced by the prestrain.
