AN X  RAY DIFFRACTION STUDY OF THE AGING TRANSFORMATION IN  Al  Li  Cu  Zr ALLOY

Abstract

Abstract: Theinitialstageofagingtransformationin Al 2 27% Li 2 68 % Cu 0 11% Zr 0 13% Ceal loy at100℃wasstudied by meansof x ray diffraction.It wasconcludedthatordering of Liatom happens whenthealloyissolution treated andquenched, and beforetheformationofδ’ phasethereexitscontinuous phasetransformation processes, namely ordering ,spinodal de composition and both coexistence. Gunier Preston zone was not found in the aging process ofthestudied alloy.

Key words: Al Li Cu Zr alloy, phase transformation, aging, spinodal decomposi tion, ordering
