The vertical alloy composition line on the partial phase diagram is for a hypoeutectoid alloy with the composition Fe - 0.38 wt % C. Before transforming to pearlite, this material phases through the ...

As was seen in the copper-nickel system, the ductility of these alloys decreases as the alloy content is increased. The hypoeutectoid steel is the most ductile and the ductility has decreased by a ...
