Abstract : The memorandum was adpted from a talk given by the author at a subgroup meeting of The Technical Cooperation Program (TTCP), London, April 1970. The author's primary theme is that there are sufficient data already available to permit the use of thermomechanical treatment (TMT) routinely in the manufacture of some alloy products. The use of TMT for products of low carbon steels, aluminum alloys, maraging steels, titanium alloys, nickel-base alloys and high-alloy steels is discussed briefly. Most of the memorandum deals with TMT of alloy steels. The future of TMT is forecast briefly, particularly with respect to alloy steels. An extensive bibliography includes sources in several languages, primarily English and Russian. A few sources in French, German, Czech, Serbo-Croatian, and Japanese are also cited.
