From July 8 to 11, 2024, the China Materials Conference 2024 and the Second World Materials Conference, hosted by the China Materials Research Society, opened grandly in Guangzhou. Nearly 100 academicians and more than 25,000 material science and technology workers attended the conference. This conference was held against the backdrop of the National Science and Technology Conference, the National Science and Technology Awards Conference, and the two academies of academicians conferences, and the whole country has just concluded the spirit of the 20th National Congress of the Communist Party of China and comprehensively promoted high-level scientific and technological self-reliance. It is an interdisciplinary, cross-field, and cross-industry academic exchange conference in the field of new materials. It is a national brand conference with more than 10,000 people in the field of new materials in China, with the highest academic level, the widest range of fields, and the latest cutting-edge dynamics.

The opening ceremony was hosted by Academician Li Yuanyuan, President of the Chinese Materials Research Society, and speeches were delivered by Academician Wei Bingbo, President of the Chinese Materials Research Society, Professor Gao Ruiping, former Deputy Director of the National Natural Science Foundation of China, and relevant leaders of Guangdong Province. The conference was awarded the International Cooperation Award for Science and Technology, the Basic Research Award, the Technological Invention Award, the Science and Technology Progress Award, the Youth Science and Technology Award, and the Doctoral Innovation Award. The conference attracted leaders from the Chinese Academy of Sciences, the Chinese Academy of Engineering, the National Natural Science Foundation of China, and other units, as well as scientific research, education, and industry workers and young students in the field of new materials worldwide. A total of more than 3.5 million people watched through the online platform.

At this conference, high-performance copper alloy experts Li Shaolin and Shi Ronghao participated in the thermal-dynamics session on structural materials hosted by the Rapid Solidification and Metastable Materials Team of Northwestern Polytechnical University and gave academic reports and introduced to the participants Their research results and application prospects in related fields. Li Shaolin gave an invited report entitled "The influence of trace amounts of rare earth Y on the structural properties of copper rod blanks and their microfilaments", revealing the mechanism of the influence of rare earth Y on the changes in the mechanical properties of single crystal copper processing lines. After adding rare earth Y, With the increase in dislocation density, the strength is significantly improved. Under high strains, with the interaction between micro/nano phases and dislocations, a "self-annealing" phenomenon occurs, recrystallization occurs in areas with larger strains, and the overall elongation increases. Shi Ronghao gave an oral report titled "Microscopic Mechanism of Plastic Work-Heat Conversion of Copper", showing that specific crystal defects will generate heat corresponding to changes in their lattice structure. The results revealed the influence of defect type, propagation path, and density on plastic heat. , providing a nanoscale explanation for the temperature rise time lag phenomenon.

"New materials are the driving force of new quality productivity." At present, China's materials science has entered a stage of rapid development, and cutting-edge research has moved to the forefront of the world. China is becoming a global new material science and innovation center, and we are gradually moving towards the goal of "a strong country in materials." This conference is a national and global event for the majority of materials science and technology workers to meet the major needs of the country, promote breakthroughs in key areas, make every effort to create the driving force of new quality productivity and plan the outbreak point of emerging industries in the future. It has further promoted academic innovation and industrial development in new materials and injected new vitality into the development of China's materials science and technology.
