Foreword

The Symposium on Temper Embrittlement in Steel was held at ASTMHeadquarters in Philadelphia, Pa., 3-4 Oct. 1967. The sponsor of thissymposium was ASTM Special Task Force on Large Turbine and Gen-erator Rotors, Subcommittee VI of Committee A-l on Steel. D. L.Newhouse, General Electric Co., presided as symposium chairman.

THIS PUBLICATION is one of manyissued by the American Society for Testing and Materialsin connection with its work of promoting knowledgeof the properties of materials and developing standardspecifications and tests for materials. Much of the dataresult from the voluntary contributions of many of thecountry's leading technical authorities from industry,scientific agencies, and government.

Over the years the Society has published many tech-nical symposiums, reports, and special books. These mayconsist of a series of technical papers, reports by theASTM technical committees, or compilations of datadeveloped in special Society groups with many organiza-tions cooperating. A list of ASTM publications andinformation on the work of the Society will be furnishedon request.
