Effect of Pulsed Current Duty Factor on Deformation Behavior of Aluminum Bronze

The effect of pulse current ratio on deformation behavior, microstructure and nature of fracture of aluminum bronze BrAZhNMts 9-4-4-1 under tension is studied. Tensile tests are performed and the structure of the bronze is determined. It is shown that pulse current ratio noticeably influences the be...

Description
Summary:The effect of pulse current ratio on deformation behavior, microstructure and nature of fracture of aluminum bronze BrAZhNMts 9-4-4-1 under tension is studied. Tensile tests are performed and the structure of the bronze is determined. It is shown that pulse current ratio noticeably influences the behavior of the stress-strain curves and bronze mechanical properties. With a minimum pulse ratio within bronze microcrack formation is possible causing accelerated failure.
