Table 2. Tensile Properties of 1 and 1.4% Silicon Containing Fe-Mn-Al-C Alloys


Figure 6. A combined non-metallic inclusion count for the 1 and 1.4% silicon containing alloys as a function of parti- cle radius. The 1.4% silicon alloy inclusion count exceeds the 1% silicon Fe-Mn-Al-C alloy for all radii. Non-metallic inclusion radii greater than 2.5 μm were not detected.


Figure 7. Tensile curves show low strength, high duc- tility for solution treated 1 and 1.4% silicon contain- ing steels. Aged material showed significant increased strength, but also showed an equally significant reduc- tion in ductility.
