The Influence on the Hardness and Form of U75V from the Different Cooling Rates

Abstract:

This paper analyzes the TTT and CCT curves of U75V as a research basis, detailed anatomical U75V chemical properties and grain structure, through thermal simulation machine, heating 820 °C, respectively, and 920 °C, respectively, the sample detection U75V 2 °C / s, 4 °C / s, 6 °C / s, 10 °C / s, 15 °C / s, 20 °C / s speeds cooled Rockwell hardness, and observing samples taken U75V phase diagram. Through data analysis and image contrast, pearlite lamellar microstructure observation, analysis hardness and lamellar spacing, summed pairs of different cooling rates U75V organizations and hardness.
