and metal emulsification, the densities of liquid metal alloys need to be accurately known. In the present study, the densities of liquid Fe-Ni and Fe-Cr alloys were measured at 1550 ~ using the sessile drop technique. The densities that were determined were then compared with the values currently available in the literature. A SiC resistance furnace was used to perform the sessile drop experiments for density measurements. An X-ray radiographic unit was employed to image the profile of the metal droplet, contained in a conical alumina crucible, at 1550 ~ The density of the liquid alloy was subsequently determined from the contour of the droplet by numerically solving the Young-Laplace equation. Details of the experimental setup, the data acquisition, and the computational technique are available in References 1 through 5. The Fe-Ni and Fe-Cr alloys were prepared by melting measured quantities of solid pieces of the component metals in alumina crucibles using an induction furnace. The metal samples used for alloy preparation were of ultrahigh purity; the metallic purity of iron (from Noah Technology, San Antonio, TX) and chromium (from Johnson-Matthe
