摘要:

挤压成型是镁合金重要的塑性加工方式,但常规镁合金挤压加工速度远低于铝合金,导致生产效率低、成本高,限制了镁合金挤压型材的大规模应用。 高速挤压技术通过高应变速率引发的绝热温升、动态再结晶(DRX)细化和过饱和固溶等效应,为提高镁合金挤压速度提供可能性。 此外,镁合金的成分对其可挤压性影响较大,只有部分镁合金体系适合高速挤压成型。 本文系统综述了应变速率、温度及合金成分对高速挤压镁合金微观组织与力学性能的协同调控机制,总结了当前的研究进展,并展望了未来发展方向,以推动该技术在工业中的大规模应用。

Abstract:

Extrusion forming is an important plastic processing method for magnesium alloys. However, the conventional extrusion speed of magnesium alloys is much lower than that of aluminum alloys, resulting in low production efficiency and high cost, which limits the large-scale application of extruded magnesium alloy profiles. High-speed extrusion technology provides a possibility for increasing the extrusion speed of magnesium alloys through effects such as adiabatic temperature rise, dynamic recrystallization (DRX) refinement, and supersaturated solid solution induced by high strain rates. Furthermore, the composition of magnesium alloys has a significant impact on their extrudability, and only some magnesium alloy systems are suitable for high-speed extrusion forming. This paper systematically reviews the synergistic regulation mechanisms of strain rate, temperature, and alloy composition on the microstructure and mechanical properties of high-speed extruded magnesium alloys, summarizes the current research progress, and prospects the future development directions, so as to promote the application of this technology in large-scale industry.

Key words: Magnesium alloys, High-speed extrusion, Strain rate, Temperature, Alloy composition, Microstructure, Mechanical properties
