24. Work Hardening, noun. In metallurgy, the name given to one of the ways in which a material can be strengthened. Work hardening a metal involves physically deforming it, through such means as hammering, rolling, stretching, or pushing it through a mold. This strain alters the crystal structure of the material—but each dislocation is itself an obstacle to future slips. A work hardened metal is less likely to yield or crack under stress. Some injuries, if leveled by design, produce an object perfectly adapted for its use: a silver ring that’s pounded into toughness for the years, a sheet of steel with all its brittleness milled out. But some, if accidentally applied, produce a metal that’s too hard to work with—and will bite back against machining. These never let themselves be cut into the shape that’s needed.
