摘要：

In this work, influences of temperature and hot working on microstructure evolution of a Nickel Aluminum Bronze alloy (NAB) were studied. First, as-cast NAB alloy was annealed and subsequently cooled in air for obtaining homogeneous structure. Microstructure and mechanical properties of NAB specimens before and after annealing were characterized by tensile test, hardness test, optical microscopy and scanning electron microscopy. Then, annealed NAB samples were heat treated at different temperatures between 750 degrees C and 1000 degrees C and rapidly cooled down to room temperature. The results showed that amounts and types of emerged microstructures and corresponding hardness strongly depended on the applied temperatures. Additionally, hot compression tests during the temperature range of 800 degrees C and 950 degrees C were performed for the annealed NAB alloy. After forming, specimens were cooled down with two different cooling rates of 40 degrees C/s and 100 degrees C/s. Developed microstructure and resulting hardness of the deformed NAB alloy were discussed regarding to the heat treating conditions. (C) 2014 Elsevier Ltd. All rights reserved.
