EFFECT OF ALUMINUM CONCENTRATION ON THE MICROSTRUCTURE AND MECHANICAL PROPERTIES OF NICRCONB HIGH ENTROPY ALLOYS
Abstract
The debate between growing economies and increased environmental burdens forces countries to make excessive efforts to reduce their energy consumption. The reduction of weight in structural materials, such as Al-based and Ni-based alloys that are utilized in everyday aspects, has a great potential for reducing the consumption of energy and minimizing the burden on the environment. High entropy alloys (HEAs) are a new class of multi-component alloy systems in which the design of the alloys is based not on adding solutes to a single "base" element, but rather on choosing elements that will form solid solutions when mixed with specific concentrations. In this work, we studied the effect of aluminum content on novel NiCrCoNb HEAs and produced low-cost and low-density HEAs with superior unprecedented mechanical properties through simple thermomechanical treatments.
