About TMS

Our Mission

The mission of TMS is to promote the global science and engineering professions concerned with minerals, metals, and materials.

Our Vision

The vision of TMS is to be the professional society of choice for the worldwide minerals, metals, and materials community.

Who We Are

The Minerals, Metals & Materials Society (TMS) is a professional society that connects minerals, metals, and materials scientists and engineers who work in industry, academia, and government positions around the world. We create networking, publication, and professional development opportunities by convening international conferences, publishing books and journals, administering awards, conducting short courses and training, and bringing together the professional community to address issues of common concern. We also provide leadership in the professional licensing of engineers and in the accreditation of university programs in metallurgical, materials, and similarly named engineering programs.

TMS currently supports nearly 14,000 professional and student members on six continents. For a more complete look at the technology areas we serve, view our listing of Technical Divisions & Committees.

TMS Diversity Statement

The Minerals, Metals & Materials Society (TMS) is committed to advancing diversity in the minerals, metals, and materials professions, and to promoting an inclusive professional culture that welcomes and engages all who seek to contribute to the field. TMS recognizes that a diverse minerals, metals, and materials workforce is critical to ensuring that all viewpoints, perspectives, and talents are brought to bear in addressing complex science and engineering challenges. To build and nurture this diverse professional community, TMS welcomes and actively engages the participation of underrepresented groups in all of its initiatives and endeavors.

Our History

The story of TMS begins in 1871, the year that its parent organization, The American Institute of Mining Engineers (now the American Institute of Mining, Metallurgical, and Petroleum Engineers—AIME), held its first meeting to read and discuss research papers and established itself as one of the first national engineering societies in the United States.

Over the years, the Society has grown and evolved along with the minerals, metals, and materials science and engineering disciplines. View Our History page to read JOM articles on the Society’s past, to hear oral histories from our members, and to explore our interactive historical timeline.
