Iron-phosphorus-carbon system Part 1 - Mechanical properties of low carboniron-phosphorus alloys

As part of a wider archeometallurgical investigation the present paper reco rds the results of mechanical tests on iron-phosphorus alloys, which were i mportant in early iron usage, Phosphorus increases the yield and ultimate t ensile strengths with a corresponding reduction in ductilities as measured by elongation and reduction in area, to a point where brittle failure occur s. However, the work hardening exponent is only slightly decreased and some cold working, as in drawing, can be achieved. The presence of carbon compl icates these effects. MST/4363.
