Puzzler: Most steel reinforcing bars manufactured in the U.S. exhibit a sharp yield plateau. Two exceptions, however, are bars that are quenched and tempered and bars that are coiled immediately after they are hot rolled. The coiled bars are later straightened by a fabricator. Both (1) quenched-and-tempered bars and (2) straightened bars have stress-strain curves that are initially linear, but yielding is gradual, producing what is described as a "round-house" curve. The reason for the round-house behavior is the same for both types of steel. Why do these two types of reinforcing steel exhibit gradual yielding rather than a sharp yield plateau even if the same steel exhibits a sharp yield plateau if it is not quenched and tempered or coiled?
