This MSIA series proceeding includes original, peer-reviewed research papers from the 6th International Conference on Materials Science and Industrial Applications (MSIA 2024), and held on April 20-21, 2024 in Xi'an, China. MSIA aims to bring together leading academic scientists, researchers and research scholars to exchange and share their experiences and research results on all aspects of Materials Science and Industrial Applications. It also provides a platform for academic scientists, research scholars, doctors, engineers, doctoral students and related professionals to present and discuss the most recent innovations, trends, and concerns as well as practical challenges encountered and solutions adopted in the fields of Materials Science and Industrial Applications. All authors and participants are kindly encouraged to contribute to and help shape the conference through submissions of their research abstracts, papers and posters. This MSIA 2024 received only 55 manuscripts, and less than half of the manuscripts had been accepted by our reviewers and 36 one-page submissions made an oral presentation ONLINE during MSIA 2024 without paper publication. All submissions to the MSIA 2024 were sent to two reviewers and evaluated based on originality, technical and research content, relevance to conference, contributions, and readability. The full paper submissions were chosen based on technical merit, interest, applicability, and how well they fit a coherent and balanced technical program. Hopefully, all participants and other interested readers could benefit scientifically from the proceedings and find it stimulating in the process. With our warmest regards, Yanwei Zhu, Jun Xiao
