The HTMC aims to promote awareness of developments and needs for change in standards, specifications and codes directed towards achieving improved materials properties and service reliability. Co-operation is encouraged between industrial and academic researchers through the organisation of technical meetings, conferences, symposia, workshops etc. and, through this, also supports the continuing professional development policy of the Institute of Materials, Minerals and Mining.

The HTMC aims to establish and encourage technical exchanges with and between other professional organisations in Europe, USA (TMS High Temperature Alloys Committee), Japan, China, Asia etc. with similar interests in high temperature materials, and via IOM3 through the organisation of international conferences.

Membership is primarily from Institute members experienced in the manufacturing and user industries, as well as experts from research organisations and universities. It aims to have a strong industrial and user bias. Appropriate experts may also be temporarily co-opted onto scientific conference organisation committees.
