Binary Regression Investigate on Composition Tempering Temperature and Hardness（HRC）of Common Steel

Abstract:

Establish the uniform regression relation expression for these three parameters including composition of over ten kinds of common steels, composition tempering temperature and hardness (HRC) of steel, which can accurately calculate the relative values of these three parameters of over ten kinds of common steels within the discussed scope. Binary regression analysis can be expanded to any Tempering temperature and each kind of steel grade, and the work can be fulfilled with computer. Furthermore express other thermal treatment process parameters and its corresponding mechanical property of each kind of steel with the uniform mathematic relation, so that related uniform regression relation expression can be used into the actual production process, and this is what the author will complete further.
