- TITLE: MODELLING, RESEARCH AND OPTIMIZATION OF CARBIDIC AUSTEMPERED DUCTILE IRON DURING ABRASION AND DRY FRICTION
- ABSTRACT: This article presents the outcomes from experimental investigation of the wear resistance of specimens made of carbidic austempered ductile iron (CADI) which are isothermally hardened in the fields of upper and lower bainite. The specimens are subjected of abrasive wear and dry friction. A mathematical modeling of the experimental results has been carried out. A regression analysis and analysis of variance (ANOVA) have been fulfiled using QStatLab package. On the basic of the regression models obtained, three single-purpose optimization tasks have been solved in order to determined the maximum wear resistance of CADI.
