"WebFeb 2, 2024 · At a certain level of stress, however, they reach a well-understood yield point. Once they reach that yield point, the metal becomes strain hardened. The metal becomes less ductile and, in one sense, becomes harder. But while strain hardening makes it less easy for the metal to deform, it also makes the metal more brittle.
