Austenite hardening measurement and prediction of final ferric grain in hot steel, involves evaluation of ferric grain of lamination route, where suitability of the chosen processing route is determined by the degree of austenite hardening

摘要

The measurement and prediction involves evaluation of the ferric grain of a lamination route. The suitability of the chosen processing route is determined by the degree of hardening of austenite, reached during the lamination. Reunion of accumulated tension is done in analogous conditions for industrial process when observation data is not available in thermo mechanical laboratory tests. The lamination route generates forty tensions to sharpen the beneficial grain for the mechanical properties.
