Density of liquid if steel containing Ti

Abstract

Density of liquid IF Steel containing Ti was measured with the modified sessile drop method at a temperature range from 1 530 to 1 610°C. Densities of pure molten Fe measured at a temperature range between 1 550°C and 1 600°C were quite close to those obtained by Saito et al., but a little lower than their results at temperature higher than 1 600°C. Thermal expansion coefficient of molten IF steel containing Ti increased linearly with an increase in titanium content. The density of the liquid IF steel was described as a function of the temperature and Ti content as follows: ρ=7.05-4. 73×10-2[%Ti]-(1.05+0.66[%Ti])×10-3(T-1 530) © 2005 ISIJ.
