While [T.sub.g] slightly increased after cold drawing, there was no endotherm of chain relaxation, which also indicates that the polymer chains were highly orientated.
The aim of the experimental work was to determine the influence of the effective strain reached by cold drawing to springback ratio and springback angle of steel X6Cr13.
Fabricated by hot and cold drawing, these clad products have a smooth, consistent surface finish and the cladding can be produced thinner than filled- and thicker than plated wire or ribbon, and are more ductile and formable.
Two or three stretches are typical of cold drawing, but Macro believes the five-stretch series is a record.
Rathbone's alignment keys are made by a combination of cold rolling and cold drawing and feature a smooth surface finish.
A special importance in the technological process of cold drawing of bars is held by the preparation of materials, including the removal of oxides, aimed to achieve a flawless surface as well as to maintain lubrication while drawing.
Stress-whitening normally begins to form when applied stress exceeds the yield point of crystalline polymers, or is associated with cold drawing. Although it is widely believed that stress-whitening is some combinations of crazes and voids, the microstructure of stress-whitening depends on polymer systems: a single or multiple phase systems.
