Publication number: 20180299036Abstract: Disclosed are high strength tubular devices for use in oil and gas well drilling and completions, oil and gas well intervention, and/or production systems. The high strength tubular devices include a pipe component and a secondary layer on the surface of the pipe component. The secondary layer can be either a continuous or partial layer and includes a nanostructured alloy. Alloy compositions are disclosed. Methods for forming the tubular devices are disclosed. The secondary layer can be formed on the pipe component by welding or casting. The tubular devices can be used in conductors, casing, drill pipe, production tubing, pipeline and risers.Type: ApplicationFiled: April 13, 2017Publication date: October 18, 2018Inventors: Grzegorz J Kusinski, Justin L. Cheney

Publication number: 20080236709Abstract: Strain-hardened steel alloys having a high tensile strength are prepared by cold working of alloys whose microstructure includes grains in which laths of martensite alternate with thin films of stabilized austenite. Due to the high dislocation density of this microstructure and the tendency of the strains to move between the martensite and austenite phases, the strains created by cold working provide the microstructure with unique mechanical properties including a high tensile strength. Surprisingly, this is achieved without the need for intermediate heat treatments (patenting, in the case of steel wire) of the steel between cold working reductions.Type: ApplicationFiled: June 3, 2008Publication date: October 2, 2008Applicant: MMFX Technologies CorporationInventors: Grzegorz J.

Patent number: 7214278Abstract: A carbon steel alloy that exhibits the combined properties of high strength, ductility, and corrosion resistance is one whose microstructure contains ferrite regions combined with martensite-austenite regions, with carbide precipitates dispersed in the ferrite regions but without carbide precipitates are any of the interfaces between different phases. The microstructure thus contains of four distinct phases: (1) martensite laths separated by (2) thin films of retained austenite, plus (3) ferrite regions containing (4) carbide precipitates. In certain embodiments, the microstructure further contains carbide-free ferrite regions.Type: GrantFiled: December 29, 2004Date of Patent: May 8, 2007Assignee: MMFX Technologies CorporationInventors: Grzegorz J. Kusinski, Gareth Thomas

Patent number: 7118637Abstract: Carbon steels of high performance are disclosed that contain dislocated lath structures in which laths of martensite alternate with thin films of austenite, but in which each grain of the dislocated lath structure is limited to a single microstructure variant by orienting all austenite thin films in the same direction. This is achieved by careful control of the grain size to less than ten microns. Further improvement in the performance of the steel is achieved by processing the steel in such a way that the formation of bainite, pearlite, and interphase precipitation is avoided.Type: GrantFiled: April 2, 2003Date of Patent: October 10, 2006Assignee: MMFX Technologies CorporationInventors: Grzegorz J. Kusinski, David Pollack, Gareth Thomas

Patent number: 6827797Abstract: Carbon steels of high performance are disclosed that contain a three-phase microstructure consisting of grains of ferrite fused with grains that contain dislocated lath structures in which laths of martensite alternate with thin films of austenite. The microstructure can be formed by a unique method of austenization followed by multi-phase cooling in a manner that avoids bainite and pearlite formation and precipitation at phase interfaces. The desired microstructure can be obtained by casting, heat treatment, on-line rolling, forging, and other common metallurgical processing procedures, and yields superior combinations of mechanical and corrosion properties.Type: GrantFiled: March 31, 2003Date of Patent: December 7, 2004Assignee: MMFX Technologies CorporationInventors: Grzegorz J.
