Since most of the creep and creeprupture tests from which design data on high-temperature alloys can be obtained are carried out in normal atmospheres and since most high-temperature materials are used in atmospheres of water vapor or some products of combustion, the design engineer must always be concerned with the effects of the environment upon the creep rate and the ductility of the material that he uses. It was with the hope of contributing to the understanding of these effects that the General Research Panel of the ASTM-ASME Joint Committee on Effect of Temperature on the Properties of Metals decided to sponsor this Symposium. It was felt that there must be data on oxidation and surface effects and on creep under controlled atmospheres that the panel could collect in one publication, and that by so doing, further work in this field would be stimulated. The solicitation of the panel brought in six manuscripts on oxidation and surface effects. It is the opinion of the chairman that the papers which make up this Symposium represent rather accurately the status of the problem of environment at the present time. Important and valuable work is being done in the field of surface reactions, but there is still a need for encouragement of creep testing under controlled atmospheres.
