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.

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.

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.

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.
