High Speed Dilatometer and the Transformational Behavior of Six Steels (BuShips Welding Test No. 329)

Abstract

This report describes a high speed dilatometer capable of measuring transformations in steel with cooling rates up to 500 degrees C per second. The transformational behavior of six commercial steels is presented; two of these steels were high tensile steels of the manganese-titanium treated type of almost identical chemical composition. A careful study of the weldability of these two steels indicated that one of the steels was more weldable than the other; the transformational diagrams obtained indicate that the most weldable steel requires more drastic cooling in order to obtain a martensitic structure. Additional information regarding the transformational characteristics of steels of this type will be highly desirable in the evaluation of the effect of minor constituents on any such property as weldability.
