Transformation and Non-Bond Tester for Flat Elements

Description: From abstract: "A composite ultrasonic unit was developed to indicate the size and location of non-bonded areas and the presence of non-transformed regions in flat uranium fuel elements clad with aluminum. A two-dimensional recorder was developed to yield instantaneous, permanent records of the non-bonded areas on electrosensitive paper. Panel lights indicate the presence of non-transformed regions that have not received proper heat treatment. Defects 1/8" in diameter are consistently detected … more

Ultrasonic Energy Applied to Aluminum Extrusion Cladding of Tubes

Description: Technical report. From Abstract: "Ultrasonic energy appropriately applied to the die or container of a laboratory-type direct extrusion press effected a marked increase in the free extrusion rate of lead and aluminum billets at a constant extrusion rate. the same results were obtained in extrusion cladding steel tubes with aluminum. Rate increases were generally 100 per cent or greater, and decreases in force were usually within the range of 10 to 20 per cent. Furthermore, the shape and slope o… more

Ultrasonic Fusion Joining of Sintered Aluminum Powder Materials to Aluminum Alloys

Description: From abstract: "Essentially void-free fusion-type joints of high strength were produced between small specimens of Type M-276 sintered aluminum powder plate and 1100 Hl4 wrought plate, using a technique consisting of controlled and brief exposure of the ends of both materials to an ultrasonically active coupler face in a bath of molten 1100 aluminum, followed immediately by butt joining and fast cooling. With further development, the process should be adaptable to other types of sintered alumin… more

Zircaloy Cladding Thickness Testers

Description: Technical report. From Abstract : "A number of similar eddy current instruments were developed to measure the thickness of Zircaloy over uranium metal in the range of 5 to 25 mils, Zircaloy over UO2 in the range of 20 to 40 mils, and the wall thickness of Zircaloy tubes in the range of 20 to 40 mils. The instruments were designed for use with hand-held probes or with feeder-mounted probes to measure the inside and outside cladding thickness of tubular elements and the wall thickness of Zircaloy… more
