GTAW در روش UDIMET بررسي تغييرات ريزساختار جوش سوپرآلياژ پايه نيكل 025

In this research the properties of Nickel base super alloy welding UDIMET 520 with worked Nickel base super alloy UDIMET 520 has bean compared from metalography studies point of view and XRD. The results of metalography studies of establishing MC thin carbides in between and on the inside of Dentertic arms and establishing a solid base phase full of Mo and W, show the result of lack of recognized XRD studies, recognition of current phases in welding structures for little volume of its existence phases and lack of having a useful welding of Nickel base alloy.
