摘要翻译：
在室温下，对Al-2.5%Mg合金多晶试样进行了较宽应变率下的拉伸试验，观察到了Portevin-Le Chatelier(PLC)效应。利用基于递推图(RP)和递推量化分析(RQA)的递推分析技术，对实验应力-时间序列数据进行了分析，研究了PLC效应的动力学行为随加载应变率的变化。我们的研究表明，RQA能够检测出PLC动态过程中特有的交叉现象。

英文摘要：
Tensile tests were carried out by deforming polycrystalline samples of Al-2.5%Mg alloy at room temperature in a wide range of strain rates where the Portevin-Le Chatelier (PLC) effect was observed. The experimental stress-time series data have been analyzed using the recurrence analysis technique based on the Recurrence Plot (RP) and the Recurrence Quantification Analysis (RQA) to study the change in the dynamical behavior of the PLC effect with the imposed strain rate. Our study revealed that the RQA is able to detect the unique crossover phenomenon in the PLC dynamics.
