Abstract
The deoxidation of: steel at 1600°C. was achieved by the use of Mn-Si-Al alloys. Steels containing silicate inclusions of various compositions were deformed by rolling, and the deformation of these inclusions was studied with reference to variousparameters.
Electron-probe micro analysis revealed that the ‘as cast' inclusion compositions varied with respect to inclusion size.
The 'Relative Plasticity indices! of deformed inclusions haw been measured and related to inclusion
size, composition, matrix strain and the temperature of deformation. In addition attention has been
focussed upon the measurement of ‘relative plasticity! values obtained from other orthogonal planes.
It was shown that inclusions less than approximately 2 µm in diameter did not deform under any of the imposed deformation conditions. The size of deformed inclusions was represented by the use of the square root of the product of their major and minor axes...
