Superplastic Deformation Characteristics in Powder Metallurgy Al-Li Aluminum Alloy
분말야금 Al-Li 합금의 초소성 변형 특성
Abstract
The superplastic deformation characteristics is powder metallurgy(PM) Al-Li alloy has been studied within the framework of a recently proposed internal variable theory of superplasticity(SSP). The flow curves were obtained by performing a series of load relaxation tests at the temperature range from 45
