Description/Abstract:
THE JOMINY END QUENCHING TECHNIQUE WAS APPLIED. FOR COOLING RATES RANGING FROM 0.002 TO 0.003 C/SECOND, IT WAS DETD THAT U HYDRIDE NUCLEATED PRIMARILY AT GRAIN BOUNDARIES EITHER AS DISCRETE PARTICLES OR IN CONJUNCTION WITH CARBIDE TYPE INCLUSIONS. THE SIZE OF THE HYDRIDE PPT INCREASED, AND THE NUMBER DECREASED, WITH DECREASING COOLING RATE. A HEAT TINTING TECHNIQUE WAS DEVELOPED FOR POSITIVE IDENTIFICATION OF THE HYDRIDE PPT. APPENDIXES GIVE (1) JOMINY END QUENCHING TECHNIQUE AND COOLING RATE CALCNS (2) POLISHING PROCEDURE FOR STUDY OF U HYDRIDE IN U (3) POPULATION DENSITY DETN (4) POLISHING AND ETCHING PROCEDURE FOR STUDY OF U HYDRIDE NETWORK AT GRAIN BOUNDARIES (5) POLISHING PROCEDURE FOR STUDY FO U GRAIN STRUCTURE UNDER POLARIZED ILLUMINATION.
