THE HARDNESS HV1 ANALYSIS OF AUTOMOTIVE STEELS SHEETS AFTER A PLASTIC DEFORMATION
Abstract
The aim of this work was to perform an analysis of increment of deformation characteristics on automotive steels sheets. For that purpose behaviour of three automotive steel sheets has been observed in this contribution. Steels were loaded by static tension with the loading rate 1.3 mm/min. Localization of deformation has been get after tensile strength and a videoextensometry method was used for scanning of the distribution of increase deformation nearly before fracture. For establishing local property of steels has been measured hardness HV1. Hardness HV 1 was measured in 2 columns as below: on the utmost of samples and on the centre of samples. Hardness HV1 of investigated steel was increased in order to IF, HR 45 and DP that was corresponded to the strength of the steels.
