Structures produced in rapidly solidified alloys( Book )

An investigation was made of the dendritic structures formed during the solidification or freezing of relatively non-dilute engineering alloys. The form and dimensional character of the dentritic structure as influenced by the freezing rate and the properties of the cast structure were of principle interest. Arc deposits from consumable and non-comsumable (W) electrodes with Al, Cu, and Ni alloys were used. Such deposits are castings of a sort and the conditions of freezing can be closely controlled. The dendrite spacings increased parabolically with the energy input. Interdendritic undercooling in the order of 0.1 F, in dilute alloys appeared to be a property of the solvent metal, did not vary significantly from one solute element to another, and was quite independent of the rate of solidification. The arc deposits froze much faster than chill castings and had smaller dendrite arm spacings than would be expected in any casting process. The minimum time for effective solution heat treatment of arc deposits, as reflected in final properties, depended on dendrite spacing (energy input). The dendrite arms in Al, Cu, and Ni alloys were generally parallel to the direction of heat flow
Mechanical and metallurgical behavior of restrained welds in submarine steels( Book )

1 edition published in 1966 in English and held by 1 WorldCat member library worldwide

The study was made to develop a greater understanding of the thermomechanical aspects of the fusion welding process, particularly the dynamics of residual stress development and its significance in the cracking of HY - 130/150 steel. A method was developed by which the residual stress distribution in an near a weld can be completely and accurately determined. Weldment residual stresses can be obtained rapidly and economically using only standard strain measuring and machining techniques. Three different plate materials HY-130/150, HY-80, and 12% maraging steels were studied. The nominal base metal yield strengths varied from 80,000 to 175,000 pounds per square inch. In HY-80 weldments the maximum residual stresses are longitudinal and of the order of the base metal yield strength. They were a maximum at the weld centerline. In HY130/150 and 12% Ni maraging steels, the maximum tensile stresses are again in the direction of welding. These maximum stress values occur, however, in the weld heat-affected-zone, far removed from the fusion line. Extremely high stress gradients were present in these regions. The observation that weldment residual stresses may be a maximum in regions other than the deposit has apparently not been reported before. An explanation of alloy-to-alloy differences based on the relative temperatures of hot plastic deformation and austenite transformation is proposed
Evaluation of electron beam welding for fabrication of ultra high strength steel rocket motor cases( Book )

1 edition published in 1961 in English and held by 1 WorldCat member library worldwide

Tensile and tensile impact properties are tabulated for electron-beam welded H-11 steel with a variety of post-weld heat treatments. Fracture occurred outside the weld zone in more than half the specimens. Decreasing the tempering temperature caused an increase in both the strength and ductility. Electron beam re-fusion of arc welds resulted in transverse properties comparable to those obtained by electron beam welding gun with a transmission of 90% under vacuum welding conditions. By correlating hardness and peak temperature distributions, the minimum hardness in the heat-affected zone corresponded to a temperature between l350 and l400 F. The magnitude of the minimum hardness was sensitive to the heat treatment of the material prior to welding; the lower the prior tempering temperature, the less was the softening effect
