FERNANDEZ COLUMBIE, Tomás; RODRIGUEZ GONZALEZ, Isnel; ALCANTARA BORGES, Dayanis  and  FERNANDEZ, Esther. A procedure for hardening steel 45 by plastic deformation using a simple roller. Ing. Investig. [online]. 2008, vol.28, n.1, pp.15-21. ISSN 0120-5609.

The work shows the techniques employees in an experiment design that allows to evaluate the behavior of the independent variables force (P), from 500 up to 2500 N, revolution number (n) minimum 27, half 54 and maximum 110 rev/min and advance (s), 0,075, 0, 125 and 0,25 mm/rev, to determine the behavior of the variable dependent hardness (H), when a steel test tube AISI 1045 are subjected to superficial treatment for rolling to create a compressive state that the unsightly thing and increase its resistance to abrasive wear and the fatigue. He/she is carried out the statistical prosecution of the variables involved in the process where the increment of the hardness is demonstrated from 220 up to 262 HV. The method of optic microscopy was used to analyze the effect of the hardening for deformation, establishing the mechanism of hardening of the steel for the slip of the grains in the crystalline net for the phenomenon of the acrimony.

Keywords : plastic deformation; rolling; variables; experiment design; acrimony; slip.
