n: plastic deformation of metal at a temperature low enough to insure or cause permanent strain.

n: one of the earliest methods for bending pipe. The joint was first placed over a small bonfire and, when the heat had rendered it sufficiently malleable, it was placed against a tree and pressure was applied until the desired benk was achieved. Fire bends significantly weakened the pipe. A cold-work process is less damaging.

n: the process of bending joints so that a pipeline will conform to the topography of a right-of-way. Pipe bends are made by the cold-work: process.

n: hardness developed in metals as a result of cold-working.

a metal deterioration in which the metal becomes progressively harder and more brittle with repeated application of load.
