Abstract

Due to the excellent high temperature performance and corrosion resistance

Al precipitation strengthening superalloys become the most commonly used engineering material in aerospace and energy industry. After the development in decades

Al precipitation strengthening superalloys were evolved from the poly crystal to the single crystal

and the ability to withstand high temperature was continuously enhanced. The mechanical properties of Ni

Al precipitation strengthening superalloys mainly depend on the microstructural characteristics of alloying elements

precipitates

and grain constitute

and improvement of the microstructure is an effective way to raise performances of the alloy. The research progress in electron beam welding on Ni

Al precipitation strengthening superalloys was briefly introduced from the aspects of macro-forming

microstructure and mechanical properties

and prospects were also expounded.
