2091铝锂合金的强化机制

Strengthening Mechanisms of 2091 Aluminium-Lithium Alloys

摘要:

综合评述了２０９１铝锂合金中可能存在的各种内强化机制。给出了它们对强度贡献的解析表达式；解释了２０９１合金比其他牌号铝锂合金具有更好的强韧性和塑性综合性能指标的原因。指出了提高综合力学性能指标的基本途径和方法。

Abstract:

he possible interior strengthening mechanisms related to 2091 Aluminium-Lithium alloy are discussed in detail in the present paper, and the analycal solutions of these mechanisms for the alloy strength are converted out. The reason why 2091 alloy has the higher ductility and mechanical properties than other kinds of Al-Li alloys is given in some extent of detail. Some basic methods improving the synthetical mechanical properties are also introduced.
