    摘要: A reducing support ring for a bridge plug and a bridge plug for sealing or packing boreholes or wells. The reducing support ring for the bridge plug includes a ring-shaped body with a setting surface provided on a circumferential outer wall or end face of the ring-shaped body. Deformation of the ring-shaped body under an axial compression force allows the setting surface of the ring-shaped body to be abutted against and positioned on an inner wall of a sleeve where a bridge plug is located and to form a surface contact-type sealed connection with the inner wall of the sleeve. The bridge plug includes the reducing support ring. The reducing support ring and the bridge plug improve the plugging effect and anchoring performance of the bridge plug and the convenience of construction.

    摘要: An aluminum alloy thick plate is formed of an aluminum alloy including Mg of 2.0 to 5.0 mass %. The aluminum alloy thick plate has a plate thickness of 300 to 400 mm. A is 160 pieces/cm2 or less and B is 1.15 times or more as large as A, where (i) A (pieces/cm2) is a maximum value in numbers of porosities with an equivalent circle diameter of 50 μm or more in each of positions located at a center portion in a plate thickness direction and at positions of 0.39 Wa to 0.48 Wa in a plate width direction; and (ii) B (pieces/cm2) is a maximum value in numbers of porosities with an equivalent circle diameter of 50 μm or more in each of positions located at the center portion in the plate thickness direction and at positions of 0.12 Wa to 0.30 Wa in the plate width direction.

    摘要: Some variations provide an aluminum alloy feedstock for additive manufacturing, the aluminum alloy feedstock comprising from 79.8 wt % to 88.3 wt % aluminum; from 1.1 wt % to 2.1 wt % copper; from 3.0 wt % to 4.6 wt % magnesium; from 7.1 wt % to 9.0 wt % zinc; and from 0.5 wt % to 2.8 wt % zirconium as a grain-refiner element. The aluminum alloy feedstock may be in the form of an ingot powder. In some variations, the aluminum alloy feedstock comprises from 81.3 wt % to about 87.8 wt % aluminum; from 1.2 wt % to 2.0 wt % copper; from 3.2 wt % to 4.4 wt % magnesium; from 7.3 wt % to 8.7 wt % zinc; and from 0.5 wt % to 2.8 wt % zirconium.

    摘要: Provided is an Al—Mg alloy plate for molding, having excellent press formability, little stretcher strain (SS) mark generation, and not generating any new issues such as reduced bending properties as a result of age-hardening at room temperature, while using more accurate and simple structural indicators. As a result, the Al—Mg aluminum alloy plate comprising a specific composition including Cu has a plate structure having an average particle diameter of 0.5-6.0 nm in a minute particle (cluster) particle distribution measured using an X-ray scattering method, controls the volume fraction to at least 0.03%, is unlikely to have serration, and suppresses SS mark generation during press forming.
