Abstract: The microstructure and properties of the rapidly solidified Al-Li-Mg-Zr alloy,in relation to the particle size of supersonic atomizing powder,have been investigated.The finer the size and the structure of powder,the higher the strength of the alloy.While the overfine powder may worsen plasticity of the alloy.The proper powder seems to be sized 40—100um.

Key words: Al-Li alloy, rapid solidification microstructure, property
