US Patent:

44810431, Nov 6, 1984
Filed:

Dec 7, 1982
Appl. No.:

6/447727
Inventors:

Arthur F. Steeves - Schenectady NY
Albert E. Bibb - Clifton Park NY
Assignee:

The United States of America as represented by the United States
Department of Energy - Washington DC
International Classification:

C22F 116
US Classification:

148 203
Abstract:

A process of producing a NiCrFe alloy having a high resistance to stress corrosion cracking comprising heating a NiCrFe alloy to a temperature sufficient to enable the carbon present in the alloy body in the form of carbide deposits to enter into solution, rapidly cool the alloy body, and heat the cooled body to a temperature between 1100. degree. to 1500. degree. F. for about 1 to 30 hours.

US Patent:

43009808, Nov 17, 1981
Filed:

May 28, 1980
Appl. No.:

6/154172
Inventors:

Arthur F. Steeves - Schenectady NY
James C. Stewart - Loudonville NY
Assignee:

The United States of America as represented by the United States
Department of Energy - Washington DC
International Classification:

C23F 102
US Classification:

156626
Abstract:

A double overlapping etch zone technique for evaluation of the resistance of metallic alloys to stress corrosion cracking. The technique involves evaluating the metallic alloy along the line of demarcation between an overlapping double etch zone and single etch zone formed on the metallic alloy surface.

US Patent:

43057799, Dec 15, 1981
Filed:

May 28, 1980
Appl. No.:

6/154171
Inventors:

Arthur F. Steeves - Schenectady NY
Donald P. Buono - Schenectady NY
Assignee:

The United States of America as represented by the United States
Department of Energy - Washington DC
International Classification:

B24B 100
US Classification:

156636
Abstract:

A chemical attack polish and polishing procedure for use on metal surfaces such as nickel base alloys and stainless steels. The chemical attack polish comprises Fe(NO. sub. 3). sub. 3, concentrated CH. sub. 3 COOH, concentrated H. sub. 2 SO. sub. 4 and H. sub. 2 O. The polishing procedure includes saturating a polishing cloth with the chemical attack polish and submicron abrasive particles and buffing the metal surface.

US Patent:

44459882, May 1, 1984
Filed:

Sep 29, 1980
Appl. No.:

6/426448
Inventors:

Arthur F. Steeves - Schenectady NY
Albert E. Bibb - Clifton Park NY
Assignee:

The United States of America as represented by the Department of Energy - Washington DC
International Classification:

C25D 538
G01N 2761
US Classification:

2041292
Abstract:

A method for detecting low levels of plastic deformation in metal articles comprising electrolytically etching a flow free surface of the metal article with nital at a current density of less than about 0. 1 amp/cm. sup. 2 and microscopically examining the etched surface to determine the presence of alternating striations. The presence of striations indicates plastic deformation in the article.
