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:

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.
