A high pressure apparatus and related methods for processing supercritical fluids is described. The apparatus includes a capsule, a heater, at least one ceramic ring with one or more scribe marks and/or cracks present. The apparatus optionally has a metal sleeve containing each ceramic ring. The apparatus also has a high-strength enclosure, end flanges with associated insulation, and a power control system. The apparatus is capable of accessing pressures and temperatures of 0.2-2 GPa and 400-1200&#xb0; C., respectively.

High pressure apparatus with stackable rings

The present invention relates to a method for the manufacturing of very high pressure vessels so that they survive high cycle fatigue loading. In particular, the method requires creating a residual tangential stress at a bore radius of a vessel such that the stress under load is more compressive than a maximum applied internal pressure. Furthermore, the method may require creating a residual stress a the inner radii of the supporting jackets such that the stress under load is compressive or zero.

Method for the manufacture of very high pressure vessels to survive high

Fatigue and fracture testing of a larger caliber cannon is accomplished by explosively thermally decomposing within the cannon bore acetylene of 0.27 grams per cc density and repeating this operation a predetermined number of times or until the surface and subsurface portions of the bore exhibit microstruictrual and other changes characteristic of those resulting from actual firing operations.
