The 17th IUMRS International Conference in Asia was held in Qingdao from October 20th to 24th, 2016. This conference contained 28 international symposia. One of symposia, titled as Serration and Noise Behavior in Advanced Materials, was well organized, which provided an effective platform to discuss the non-linear behavior in advanced materials including high-entropy alloys, bulk metallic glasses, and lightweight alloys, etc. Generally speaking, serration and noise phenomenon exist everywhere, such as, the crackling noise arising from paper crumpling, and brain wave measured by instruments, etc. In the materials science, the well-known examples are the small serrated plastic deformation after yielding in plain steels, and the serrated plastic flow in Al-Mg alloys, which are believed to be associated with interaction between the mobile solute atoms and forest dislocations. Besides those, the non-linear behavior is also observed in some advanced materials. For example, even without the dislocations, the serrated plastic deformation also can be found in bulk metallic glasses, which is dominated by shear banding. In order to deeply understand the nature of serration and noise in advanced materials, the non-linear mechanical behavior in many kinds of materials is inspected. In current special issue, twenty papers focused on the non-linear mechanical behavior are published. The topics include but are not limited to theoretical modeling, experimental characterization, and numerical simulations.
