บทคัดย่อ

In this work, effects of temperature and strain rate on microstructure development of a Nickel Aluminum Bronze (NAB) alloy during hot compression were investigated. The temperatures between 750°C and 900°C, strain rates between 0.1 s-1 and 10 s-1 and a deformation degree of 60% were considered. Microstructure analyses were performed for the samples after the compression using scanning electron microscopy technique. The results showed that microstructure of as-cast NAB alloy consisted of α, β′ and κ phase. After homogenization β′ phase transformed to the α and kappa; phase. Furthermore, different heating temperatures led to varying initial microstructures before forming and subsequent deformation, forming rates and cooling caused precipitation of various intermetallic phases. The α phase was found in the final microstructures of all forming conditions. At high forming temperatures, some intermetallic κ phases tended to dissolve and precipitated during cooling according to applied strain rate. However, at lower temperatures of 750-850°C, no significant effect of the strain rate on alteration of intermetallic κ phases. © (2014) Trans Tech Publications, Switzerland.
