Characteristics of deformation-induced transformation (DIT) in the refractory low alloy steel 2.25Cr1Mo were experimentally studied. Effect of different controlled-rolling and controlled-cooling process on the steel microstructure and mechanical properties were investigated and the mechanism was discussed. Results show that the grain size and the ferrite volume fraction were obviously affected by the rolling and cooling processes. Proper DIT technique may significantly accelerate the transformation of austenite to ferrite in the steel and improve the steel strength.

Elevated Temperature Strength

Three fire-resistant steels for construction were developed, which are low carbon Mn-Cr-Mo steel microalloyed with Nb and free Nb. The mechanical properties of the alloy were studied by tensile and impact testing. The effects of parameters in controlled rolling and controlled cooling process on the mechanical properties and the microstructures of the steel were investigated. It is found that the precipitation strengthening is important strengthening way to improve the elevated temperature strength of fire-resistant steels.

The mechanical properties of 60Si2Mn were investigated with the cooling rate changing under new finishing temperature. Results showed: the mechanical properties of 60Si2Mn plate depend on the finishing temperature and the cooling rate changing. The microstructure of ferrite and pearlitic lamellar is thinning, and sorbitic content and HV increase with the cooling rate increasing under the same finishing temperature.

Si Content

The microstructure and mechanical properties of the four spring steels with different Si content treated by Q-I-Q-T process were studied by metallographic microscope, MTS, impact testing machine and X-ray stress analyzer. The results show that the tensile strength and yield strength is first increased and then decreased with the increase of Si content, the volume fraction of retained austenite and elongation are fist decreased and then increased when the Si content is less than 2.1%, and the microstructure become finer and homogeneous. When Si content reaches 2.1%, the comprehensive properties of 60Si2CrVA spring steel is the best.
