Microstructural and Fracture Behavior of Phosphorus-Containing Fe-30Mn-9Al-1Si-0.9C-0.5Mo Alloy Steel
Five different phosphorus (P)-containing heat-treated Fe-Mn-Al-C alloys were tested in accordance with ASTM E 23 Charpy V-notch Energy (CVNE) standards. Room temperature CVNE of solution treated and quenched specimens revealed ductile fracture for 0.001 and 0.006 wt pct (pct P-containing alloys). Brittle cleavage fracture dominated the 0.043 and 0.07 pct P-containing alloys. A hard brittle P eutectic phase was observed in the 0.07 pct P-containing alloy.
