【摘要】 研究超音雾化快速凝固Al—Li—Mg—Zr合金粉末粒度对组织和性能的影响中发现,粉末粒度越细,组织越细,合金强度越大;但粒度太细,又会导致塑性变差。试验合金粒度范围选用40—100μm为佳。更多还原

【Abstract】 The microstructure and properties of the rapidlysolidified 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 are, the higher the strength of the alloy will be. While the overfine powder may worsen plasticity of the alloy. The proper powder seems to be sized 40--100 μm.更多还原
