Cold Rolling - an overview ScienceDirect Topics

Cold rolling reduction is an important factor that affects drawability of IF steel.It has been observed that increasing cold rolling reduction increases the r m value,at least up to 90% [34].This effect has been shown in Fig.5.14.Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the time of holding [35].Cold Rolling - an overview ScienceDirect TopicsWhenever appropriate,cold rolling (Figure 22) follows the hot rolling process step.Temperature ranges typically from 60°C to 180°C and the desired reduction in thickness of the material is from 6 mm to 0.06 mm.The process runs continuously at an average speed of 40 m/s.Deposition ProcessesCasting is a simple technology which can be used for a variety of materials (mostly polymers).The control on film thickness depends on exact conditions,but can be sustained within +/-10% in a wide range.If you are planning to use photolithography you will be using casting,which is
