A watch case (6) including a rotating bezel (1), a middle (3) and a connecting spring (2) between the rotating bezel (1) and the middle (3), the connecting spring (2) being accommodated within a first groove (7) formed in an external wall (3a) of the middle (3) and within a second groove (8) formed in an internal wall (1 a) of the rotating bezel (1), the first and second grooves (7,8) being preferably arranged opposite one another. The connecting spring (2) is made of an alloy with memory of shape.

A method of performing a localized post weld heat treatment on a weld seam in a thin wall metallic body may include attaching thermocouples to the outside surface of the weld seam and covering the weld seam with a thermal insulating blanket. Cooling bands are attached to the outside of the body on both sides of the weld seam. An inert atmosphere enclosure with inlet and exhaust ports is fitted over the weld seam, thermal insulating blanket, and cooling bands. A power supply and control system for an induction coil or coils situated in close proximity to the weld seam are actuated and the weld seam is subjected to a heat treatment without thermally affecting regions of the metallic body adjacent to the weld seam and external to the cooling bands.

Nickel-base composite niobium bearing alloys including delta and/or eta strengthening phases in addition to gamma prime precipitates in a gamma matrix.

The present invention relates to a nickel-based super heat resistant alloy and a method of manufacturing the same. In the nickel-based super heat resistant alloy according to the present invention, an amount of solid solution strengthening elements (chromium, cobalt, molybdenum, or tantalum) is adjusted to improve a mechanical property, such as a creep property, at high temperatures, and aluminum or titanium is included in a predetermined amount to improve a corrosion property. The nickel-based super heat resistant alloy has excellent elongation, strength, and creep properties at normal temperature and high temperatures, and thus it is possible to manufacture parts of, by way of non-limiting example, a thermoelectric power plant, an aircraft, or a very high temperature reactor in various shapes on a large scale.
