New Sheet Steel Production Processes
- Published: 09 February 2022
Researchers from NMSTU are working on developing production processes to make steel that would combine high strength and high plasticity, while no heat treatment is involved.
The study is conducted on the new asymmetric rolling mill, which can roll steel workpieces reaching a 75 to 90% reduction in one pass. The mill has been in use at Zhilyaev Mechanics of Gradient Nanomaterials Laboratory for less than a year, and over that period researchers were able to increase metal plasticity due to optimum roll velocity errors that were found. For example, if aluminium alloy D16 fractured in the common cold rolling operation when the reduction reached 43%, in the asymmetric rolling operation it was reduced by 90% gaining a double increase in plasticity.
