Abstract:
In this study, novel high entropy alloys have been produced by using mechanical alloying-powder metallurgy method. The high entropy alloys were produced for military applications. Initially, metal powders were prepared by mechanical alloying in a ball mill by using 6 mm zirconia balls for 15-20 hours at 400 rpm. Then, the high entropy alloy powder mixtures were compacted at about 400 MPa pressure in a hydraulic press, and then the green specimens were sintered in a vacuum environment at a temperature of 1250 °C for 1 hour in a horizontal tube furnace. Properties of the high entropy alloys were studied by non-destructive eddy current test and ultrasonic test. Elastic modulus of the sintered high entropy alloys was characterized by destructive compression tests and non-destructive ultrasonic tests comparatively.
