Abstract: 1472585 Heat-treating reinforced superalloys OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES 24 July 1974 [30 July 1973] 32735/74 Heading C7A A directionally solidified material comprising a complex superalloy matrix reinforced with parallel monocrystalline fibres of a transition metal monocarbide or a solid solution of two or more such carbides is heat-treated at a temperature such that the carbide phase is partially soluble in the matrix, after which the carbide is reprecipitated. The matrix may be a solid solution of Cr with one or more of Fe, Co, Ni, and may be reinforced with a carbide of V, Ta, Nb, Ti, Zr or Hf. Preferred heattreatment conditions are 1100-1300‹C followed by quenching, either directly to a precipitation temperature such as 700-1100‹C, or with reheating to that temperature. Alternatively the precipitation may be brought about by service conditions. Precipitation may be carried out in two stages, the second at a higher temperature than the first, while preferably the structure of the product is such that the diameter of the re-precipitated particles is less than that of the fibres. Compositions particularly exemplified are, in wt. per cent: Typical alloys and their manufacture are described in British Specification 1303160.

Filed: 1945-12-10
Abstract: 638,488. Ammunition cartridges. MINISTER OF SUPPLY. Dec. 10, 1945, No. 33394. [Class 9 (i)] A cartridge case for recoilless guns has an end wall, such as a disc 4, located rearwardly of the propelling charge, the wall having a thickness such that it is disrupted to permit rearward escape of the gases, the disruption taking place when the gas pressure is sufficient to move the projectile out of the case and when its driving band has become compressed by the barrel and has engaged the barrel rifling. In the construction shown, a support 5 is screwed into the base of the cartridge, this support incorporating spokes 8 radiating from a hub 6. The disc 4 is held in place by the support near its periphery and also, by a nut 11, near its centre. On firing, the gases are temporarily confined by the disc 4 but as the pressure increases the projectile is expelled and its driving band 17 is pressed into engagement with the rifling 19 of the gun barrel. At this stage the disc disrupts and the gases can escape to the rear being prevented from entering the breech and firing pin housings by thin flanges 15, 16, of the support and hub which are deformed by the gases and thus form effective seals.
