Influences of Temperature and Strain Rate on Microstructure of Manganese Aluminum Bronze Alloy

Abstract:

Manganese Aluminum Bronze has been extensively used for applications under seawater such as marine propellers, because this alloy exhibits high strength as well as excellent corrosion resistance behavior. In this work, microstructures and hardness properties of an as cast Manganese Aluminum Bronze undergoing hot deformation at different temperatures between 700^oC, 750^oC, 800^oC and 850^oC with the strain rates of 0.1s^-1 and 1s^-1 were investigated. Microstructures of the MAB alloy from each condition were characterized by both optical and scanning electron microscopy. The results showed that dynamic recrystallization obviously occurred at the temperatures higher than 800^oC for both strain rates. Finally, determined hardness values were correlated with observed microstructure evolutions.
