Effect of Tempering Temperature on Microstructure, Texture and Mechanical Properties of a High Strength Steel

2. Experimental

The chemical composition of the steel is given in Table 1. The steel was industrially hot rolled to a thickness of 25 mm. Samples were again hot rolled at a temperature of 1100°C to 5 mm from the initial thickness in a laboratory rolling mill. The specimen was deformed 10% in each pass and rolling direction was kept strictly unidirectional. After each pass, the sample was kept back into the furnace to re-attain the rolling temperature.
