Abstract:

Unidirectionally solidified high-strength steel was homogenized at 2500 F for extended periods of time. The mechanical properties resulting from such treatments were compared with the properties of the material heat treated in the standard way. The improved ductility associated with the 2500 F homogenization is attributed to a reduction in the extent of micro-segregation with increasing homogenization time. First principles were employed to show that the increase in ductility is a function of time of homogenization and diffusion coefficient of segregated alloying elements over the square of the distance from the surface of the casting to the test location.
