The correlation between hardness in Webster scale and selected mechanical properties

$15.00

The aim of this research is to analyze the correlation between hardness in the Webster scale as determined by a Webster hardness tester and selected mechanical properties: yield strength and tensile strength of hot extruded profiles from EN-AW 6060 and EN-AW 6063 aluminum alloys. Statistical analysis showed a high accuracy of correlation with errors lower than 5%. The study found a very strong correlation with coefficient correlation higher than 0.95. The elaborated system of correlation can also be used for different shapes of semi products such as bars.
