Patent number: 8192563Abstract: An actuator (12) is disclosed for example controlling gas flow in a gas turbine engine. The actuator (12) comprises a first portion (14) having shape memory properties, and a second portion (16) formed of substantially the same material as the first portion and having reduced shape memory properties relative to the first portion. The first portion (14) is movable from a first position to a second position at a temperature above the phase transition temperature of the shape memory material of the first portion (14). The second portion (16) is arranged to urge the first portion (14) from the second position to the first position at a temperature below the phase transition temperature of the shape memory material.Type: GrantFiled: May 17, 2010Date of Patent: June 5, 2012Assignee: Rolls-Royce plcInventors: Daniel Clark, John R.

Patent number: 8182617Abstract: The present invention comprises the nitrogen alloying of stainless steel with a gaseous nitrogen compound such as nitrogen gas (N2), or ammonia (NH3) at high temperature wherein the reaction pressure is lowered. A base powder with properties similar to those of a martensitic stainless steel is prepared from a molten metal with the subsequent incorporation of selective additives such as cobalt, chromium, boron, copper, vanadium, niobium and mixtures thereof to improve high temperature resistance to scuffing and adhesive wear. The molten mixture is then atomized by water- or air-atomization to yield a base powder which is mixed with nitrogen or ammonia gas at various pressures in a static or fluidized bed to provide a nitrogen alloyed particulate, i.e., a nitrided particulate alloy. The powder is heated in a hot isostatic press under vacuum with argon gas at reduced pressure and later cooled to ambient temperature.Type: GrantFiled: November 22, 2010Date of Patent: May 22, 2012Inventor: Kenneth A. Moyer
