摘要:
研究了锻造温度、锻造比等对新型高强铝锂合金成形质量的影响,总结了新型高强铝锂合金在不
同锻造比下的组织性能变化规律。结果表明:锻造比为3 ~7 时,合金热处理后径向抗拉强度均大于500 MPa,
并且其径向抗拉强度明显高于轴向;并且随着锻造比的增大,晶粒尺寸也逐渐增大。
关键词:铝锂合金,锻造,力学性能,组织
Abstract:
The mechanical properties and microstructure of a new high鄄strength Al-Li alloy is characterized as
functions of the different forging ratio after the forging process. Results show that the radial stretch strength is more
than 500 MPa, and the radial stretch strength is higher than the axial stretch strength. The grain size is increased with
the increase of the forging ratio
