Fundamental concept of metal rolling - mtixtl.com

•The friction varies from point to point along the contact arc of the roll. However it is very difficult to measure this variation in µµµµ, all theory of rolling are forced to assume a constant coefficient of friction . •For cold-rolling with lubricants, µµµµ~ 0.05 –0.10. •For hot-rolling, µµµµ~ 0.2 up to sticky condition.

High dislocation density–induced large ductility in ...

Many industrial applications require materials to have high strength while remaining pliable, or ductile. However, the microstructure that increases strength tends to reduce ductility. He et al. used a processing mechanism to create a "forest" of line defects in manganese steel. This deformed and partitioned steel was produced by cold-rolling and low-temperature annealing and contained a ...
