在应变硬化铝合金中有几种结晶机制起作用。每个机制的贡献取决于材料和工艺参数，如先前的处理历史，溶质的量，变形速率和温度，以及第二相颗粒的尺寸和体积分数。为了定量地确定每种不同的再结晶机制的程度，对冷变形和再结晶的Al-Mn（Fe，Si）铝合金进行详细的三维分析。研究表明，约50%体积的再结晶晶粒是由颗粒激励形核（PSN）形成的，20%的新形成晶粒是立方取向的，并且主要在预先存在的变形立方晶粒处形核
Several crystallization mechanisms are operative in strain hardening aluminum alloys. The contribution of each mechanism depends on the material and processing parameters such as prior processing history, amount of solute, deformation rate and temperature, and size and volume fraction of second phase particles. In order to quantitatively determine the extent of each of the different recrystallization mechanisms, a detailed three dimensional analysis of a cold deformed and recrystallized Al-Mn (Fe, Si) aluminum alloy was performed. This study showed that about 50% by volume of all recrystallized grains were formed by particle stimulated nucleation (PSN) and 20% of the newly formed grains are cube oriented and have mainly nucleated at pre-existing deformed cube grains
