Mechanical Behavior


The influence of boron levels up to 40 ppm on therm value and mechanical properties of an aluminum killed steel have been investigated. It is shown that boron levels in excess of 15 ppm cause a marked deterioration inrm value from a level of 1.7 to that of 1.2. This change inrm value is associated with a characteristic change in grain shape from elongated to equiaxed, an inhibition of aluminum nitride precipitation in the annealed sheet and a lowering of the intensity of {111{ poles. The influence of boron on aluminum nitride formation is discussed.
