Book Description
Techniques for the quantative evaluation of refinement of a high strength cast steel have been evolved and used to test the effectiveness of various inoculants in achieving microstructural and macrostructural refinement. Of the various materials tested only titanium additions produced significant refinement of both the micro and macrostructure. Comparison of the tensile properties of the basic steel with that of a refined steel shows that large additions (0.2-0.6 wt%) of titanium are sufficient to decrease the reduction in area sharply. Further data on castings partially refined with small (0.10 wt%) titanium additions indicate that an improvement in reduction of area is obtained compared to the results with a columnar structure solidified under similar thermal conditions.
