In this issue of Metallography, Microstructure, and Analysis, I would like to set aside some space to acknowledge the many volunteers who make this journal possible—our peer reviewers and guest editors. The technical reviewers for MMA perform a vital service to our community. They donate their time and their expertise to the journal and to our authors, in an effort to improve the output of the journal and ensure technical excellence in our published manuscripts. In addition, their comments and guidance help our authors become better technical communicators. Speaking for the journal’s editorial staff, I can say that nothing makes us happier than when an author writes to thank the reviewers for their useful and instructive feedback. The peer review system is not without its flaws and challenges, but it is encouraging to see how the efforts of our volunteer reviewers are acknowledged by the authors in improving their manuscripts.

Below is the list of reviewers and guest editors who contributed their time and energy to MMA in 2023. On behalf of the editorial staff of MMA and the authors who contributed their work to the journal, we here express our deepest appreciation to all of those reviewers and guest editors.
