Abstract

The impact of cryorolling (CR) and room temperature rolling (RTR) followed by artificial aging on the corrosion characteristics of 2195 Al−Li alloy (AA2195) was studied. Transmission electron microscope, scanning electron microscope, optical microscope, intergranular corrosion experiment, and electrochemical experiment were used. Throughout different stages of aging treatment, the corrosion behavior of both CR and RTR samples exhibited a sequential progression of pitting corrosion, followed by intergranular corrosion, and then pitting corrosion again. The corrosion rates of both samples initially showed an increase, followed by a gradual stabilization over time. The size and density of T₁ phase significantly influenced the corrosion performance of the alloy. During the peak aging and over-aging stages, the CR sample exhibited superior corrosion resistance to the RTR sample, attributed to its finer T₁ phase.

期刊介绍： The Transactions of Nonferrous Metals Society of China (Trans. Nonferrous Met. Soc. China), founded in 1991 and sponsored by The Nonferrous Metals Society of China, is published monthly now and mainly contains reports of original research which reflect the new progresses in the field of nonferrous metals science and technology, including mineral processing, extraction metallurgy, metallic materials and heat treatments, metal working, physical metallurgy, powder metallurgy, with the emphasis on fundamental science. It is the unique preeminent publication in English for scientists, engineers, under/post-graduates on the field of nonferrous metals industry. This journal is covered by many famous abstract/index systems and databases such as SCI Expanded, Ei Compendex Plus, INSPEC, CA, METADEX, AJ and JICST.
