Paper Title:
Effect of Heat Treatment on Microstructure and Mechanical Properties of 30MnSi Pre-Stressed Concrete Steel
  Abstract

In the present work, the effect of heat treatment parameters on microstructure and strength of the 30MnSi PC steel bars was investigated and analyzed systematically. The results show that the fine tempered martensite, thinning tempered troostite and tiny tempered sorbite can be obtained when quenching temperature reach 920°C and the temper temperature is 240°C, 430°C, 600°C, respectively. The relationship between heat treatment parameters and tensile strength was also obtained. Optimum strength can be obtained by quenching at 920-950 °C and tempering at 430 °C with constant heating time.
