Abstract

The aim of the paper is to assess mathematical relationship between alloying elements and technological deformability indexes. The subject proposed is settled through a laboratory experiment, where plasticity is appraised by pressing tests.Three steel grades are used. (OLT 35 K, 16 Mo 3, 14 CrMo 4) in order to determine their grain growth trend and their initial grain size at austenitization temperature. Structural analysis examined surfaces was performed for each steel grade for the following purposes: to determine the trend of increasing grain; determining initial grain austenitization temperature used in attempts (Ta = 12000C) determine the deformation temperature austenitic grain..

Keywords

The deformation resistance, Mathematical regressions, Microstructural analyze.
