| 141 | Zirconium alloys having an integral .beta.-quenched corrosion-resistant surface region | US972388 | 1978-12-22 | US4279667A | 1981-07-21 | Thomas R. Anthony; Harvey E. Cline |
| A body composed of a zirconium alloy is afforded enhanced corrosion resistance to a high pressure and high temperature steam environment by an integral surface region of .beta.-quenched zirconium formed in situ by laser beam scanning and afforded good mechanical and structural properties by the underlying bulk region whose metallurgical structure is selected to optimize these mechanical properties. | ||||||
| 142 | Method for improving fatigue properties in castings | US840134 | 1977-10-07 | US4171562A | 1979-10-23 | William R. Freeman; Louis E. Dardi |
| A method for producing cast, superalloy, ferrous and titanium articles comprising the formation of a material void in the cast article, for example by utilizing a core during the casting operation or by machining a void after casting. The void is sealed relative to the surrounding atmosphere and the article is then subjected to an elevated temperature and pressure treatment in a gaseous atmosphere whereby the metal in the area of the void will yield so that the void is partially or totally eliminated. The pressure application is carried out at a temperature such that local deformation of the cast structure occurs in the region previously occupied by, and adjacent to, the void whereby a fine-grained recrystallized structure is developed in this section. Grain refined cast articles are characterized by superior low-cycle fatigue and tensile properties. | ||||||

| A fast neutron-irradiated zirconium-base alloy body having load-carrying capacity substantially greater than similar conventional zirconium-base alloy bodies likewise irradiated is produced by subjecting a body heat treated at 930.degree. C. and then water-quenched and containing 0.2 weight percent beryllium and at least 95 weight percent zirconium to integrated neutron flux approximating 1.2.times.10.sup.21 nvt while maintaining the body at about 330.degree.

| 144 | High strength, corrosion resistant tubular products and methods of making the same | US786491 | 1977-04-11 | US4151012A | 1979-04-24 | Ales Simkovich; Leonard A. Pugliese |
| Tubular metal products and methods of making tubular metal products for use in sour gas wells, which are characterized by resistance to hydrogen sulfide embrittlement at temperatures up to about 600.degree. F., are provided based upon an alloy having the composition up to about 0.035% maximum carbon, up to about 0.15% maximum silicon, up to about 0.15% maximum manganese, up to about 0.010% maximum sulfur, up to about 0.015% maximum phosphorus, about 19.0% to about 21.0% chromium, about 33.0% up to 37.0% nickel, about 9.0% to about 10.5% molybdenum, up to about 1.00% titanium, up to about 0.015% boron, up to about 2% iron and the balance cobalt, said tubular product having been strengthened by explosive shock loading which may be followed by heat treatment to further strengthen the tubular product. A small amount of cold work between the explosive shock strengthening treatment and heat treatment may be used to control the size and shape of the product and provide additional strengthening if needed. This same practice may be applied to other alloys of the nickel-base, iron-nickel base, cobalt-nickel base, cobalt base and iron-nickel-cobalt base groups which are responsive to cold working to produce higher strengths and reduce sulfide stress cracking. | ||||||
| 145 | Method of producing amorphous cutting blades | US544164 | 1975-01-27 | US3940293A | 1976-02-24 | Donald E. Polk; Robert C. Morris |
| Metal alloys in an amorphous state are employed in the fabrication of cutting implements such as razor blades or knives. The implement may be formed from the amorphous metal or a coating of the amorphous metal may be applied. Such products may be formed from a ribbon of the amorphous metal alloy which has been prepared by quenching the molten metal or by coating the amorphous metal alloy on a suitable substrate such as by a sputtering procedure or vapor, chemical or electro-deposition of the alloy on the substrate. | ||||||

| A METHOD FOR REDUCING THE CONDITION OF EMBRITTLEMENT IN A METAL SPECIMEN BY IRRADIATING THE SPECIMEN WITH A NEUTRON FLUX OF SELECTED DENSITY. THE METHOD CONSISTS OF PLACING A METAL SPECIMEN IN VIEW OF NEUTRON RADIATION FOR A PRE-DETERMINED PERIOD OF TIME IN ORDER TO ALLEVIATE ANY EMBRITTLEMENT CONDITION AND/OR TO REDUCE LIKELIHOOD OF SUCH CONDITION AT A LATTER TIME, SUCH NEUTRON IRRADIATION TENDING TO REARRANGE THE INTERSTITIAL MAKEUP OF THE METAL SPECIMEN, E.G. BY BRINGING ABOUT DISSOCIATION OF DIATOMIC OR MOLECULAR HYDROGEN TO ITS MONATOMIC STATE.

| 148 | Cryogenic arc furnace and method of forming materials | US3720598D | 1970-12-31 | US3720598A | 1973-03-13 | THOMPSON W |
| This disclosure provides apparatus for achieving rapidly a high temperature arc discharge in the region of a material to be vaporized. Surrounding the region of the arc discharge is a cryogenic fluid against which both the arc and the vaporized produces exert pressure. The effect of the presence of the cryogenic fluid adjacent to the high temperature region is to constrain the arc discharge strongly and to quench rapidly the material in the vapor state to the solid state. As a consequence of the localized heating and rapid quenching in the cryogenic arc furnace, special materials and physical states thereof are achieved. Illustratively, chemical products and amorphous conditions of materials are achieved for the practice of this disclosure not heretofore contemplated in the practice of the prior art. For an embodiment of this disclosure, the material to be vaporized is ab initio established in location for a capacitive arc discharge and the capacitor plates are caused by mechanical shock to approach each other so that the discharge occurs preferentially at a preselected path on the material. Practice of this invention is readily extrapolated to the very high temperatures required for fusion experiments in liquid deuterium, e.g., greater than 100,000*C.

| 149 | Method of increasing beryllium ductility | US3699798D | 1970-12-24 | US3699798A | 1972-10-24 | ANDERSON RAYMOND H JR; WHITESON BENNETT V |
| Reorienting by planar compression loading the atomic planes of deformation in a hexagonal close-packed unit cell of a metal crystal, and in particular beryllium, to improve ductility in a bending mode. In particular ductility in the third dimension (short transverse direction) is accomplished by reorientation of existing slip systems by activating twin systems through planar compression loads. Highly textured sheet material, usually crossrolled from hot pressed block, is of particular interest.
