摘要
铝合金是目前应用最为广泛的一类有色合金。通过超声辅助液相复合法将颗粒与铝合金复合可进一步提升其力学性能。在材料科学与工程专业实验课程教学中引入“含颗粒铝合金凝固及凝固组织分析”实验,帮助学生理解颗粒对铝合金凝固过程及凝固组织的影响机理,便于学生进一步理解凝固中的形核与组织细化等核心问题。
Aluminum alloy is one of the most widely used nonferrous alloys.Adding particles into aluminum alloy can further improve its mechanical properties by using ultrasound assisted liquid compositing method.Introducing the experiment named"solidification and analysis of solidified microstructure of aluminum alloy containing particles"into the teaching of specialized course in the major of materials science and engineering,can help students to understand the influence mechanisms of particles on the aluminum,and further help students to understand the core knowledge points,such as nucleation and grain refinement.
