Patent number: 9291537Abstract: Disclosed herein are systems, devices and methods for stress-rupture testing selected materials within a high-temperature liquid salt environment. Exemplary testing systems include a load train for holding a test specimen within a heated inert gas vessel. A thermal break included in the load train can thermally insulate a load cell positioned along the load train within the inert gas vessel. The test specimen can include a cylindrical gage portion having an internal void filled with a molten salt during stress-rupture testing. The gage portion can have an inner surface area to volume ratio of greater than 20 to maximize the corrosive effect of the molten salt on the specimen material during testing. Also disclosed are methods of making a salt ingot for placement within the test specimen.Type: GrantFiled: May 14, 2014Date of Patent: March 22, 2016Assignee: UT-Battelle, LLCInventors: Weiju Ren, David E. Holcomb, Govindarajan Muralidharan, Dane F. Wilson

Patent number: 6490927Abstract: A corrosion sensor and method for its use to detect and determine the, type, location, size and growth rate of corrosion of metals and the like in a corrosive environment. The corrosion sensor can distinguish between different types of corrosion such as uniform corrosion, pitting, crevice, and stress corrosion cracking. The sensor detects corrosion conditions of a corrodible metal article in a corrosive environment. It has a metal probe comprised of a metal which is substantially identical to that of the corrodible metal article and a transducer element attached to said probe, which is capable of projecting and receiving ultrasonic or radio frequency signals through the probe. The received signals indicate corrosion of the probe and hence the corrodible metal article.Type: GrantFiled: December 22, 2000Date of Patent: December 10, 2002Assignee: Honeywell International Inc.Inventors: Russell D. Braunling, Gary S. Whittaker, Dane F. Wilson, George D. Hadden, Sunil Menon
