Triple-Phase Nano-Composite Steels

View page
US Patent:
6746548, Jun 8, 2004
Filed:
Dec 14, 2001
Appl. No.:
10/017847
Inventors:
Grzegorz J. Kusinski - Berkeley CA
David Pollack - Tustin CA
Gareth Thomas - Sonoma CA
Assignee:
MMFX Technologies Corporation - Irvine CA
International Classification:
C22C 3800
US Classification:
148320
Abstract:
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.

US Patent:

Assignee:

International Classification:
C21D 900
US Classification:

Nano-Composite Martensitic Steels

US Patent:
7118637, Oct 10, 2006
Filed:
Apr 2, 2003
Appl. No.:
10/406780
Inventors:
Grzegorz J. Kusinski - Berkeley CA, US
David Pollack - Tustin CA, US
Gareth Thomas - Sonoma CA, US
Assignee:
MMFX Technologies Corporation - Irvine CA
International Classification:
C22C 38/18
C22C 38/40
US Classification:
148660, 148333, 148336
Abstract:
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.

High-Strength Four-Phase Steel Alloys

US Patent:
7214278, May 8, 2007
Filed:
Dec 29, 2004
Appl. No.:
11/027334
Inventors:
Grzegorz J. Kusinski - Irvine CA, US
Gareth Thomas - Cassis, FR
Assignee:
MMFX Technologies Corporation - Irvine CA
International Classification:
C22C 38/18
C21D 9/00
US Classification:
148333, 148325, 148660, 148664
Abstract:
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: () martensite laths separated by () thin films of retained austenite, plus () ferrite regions containing () carbide precipitates. In certain embodiments, the microstructure further contains carbide-free ferrite regions.

Surface Treatment Of Amorphous Coatings

US Patent:
8389059, Mar 5, 2013
Filed:
Apr 28, 2010
Appl. No.:
12/769459
Inventors:
Grzegorz Jan Kusinski - Moraga CA, US
Jan H. Kusinski - Zielonki, PL
Assignee:
Chevron U.S.A. Inc. - San Ramon CA
International Classification:
B05D 3/12
US Classification:
427367
Abstract:
A method to improve corrosion, abrasion, resistance to environmental degradation and fire resistant properties of structural components for use in oil, gas, exploration, refining and petrochemical applications is provided. The structural component is suitable for use as refinery and/or petrochemical process equipment and piping, having a substrate coated with a surface-treated amorphous metal layer. The surface of the structural component is surface treated with an energy source to cause a diffusion of at least a portion of the amorphous metal layer and at least a portion of the substrate, forming a diffusion layer disposed on a substrate. The diffusion layer has a negative hardness profile with the hardness increasing from the diffusion surface in contact with the substrate to the surface away from the substrate.

Cold-Worked Steels With Packet-Lath Martensite/Austenite Microstructure

View page
US Patent:
20040149362, Aug 5, 2004
Filed:
Aug 20, 2003
Appl. No.:
10/645833
Inventors:
Grzegorz Kusinski - Irvine CA, US
Gareth Thomas - Cassis, FR
Assignee:
MMFX Technologies Corporation, a corporation of the state of California - Irvine CA
International Classification:
C21D008/00
US Classification:
148/650000
Abstract:
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.
