too hard or the design of a casting being unsuitable. Hammond
To draw (as metal) while cold or without the application of heat.

prestressing is made by this process. Hammond

stamping. Within limits, in treatment of iron, copper, aluminum, induces
work hardening, thus increasing strength. If carried too far, brittleness
results. Metal that is brittle when cold is termed cold-short.
