Book Description
Slow strain-rate technique provides a rapid and reliable method to determine stress corrosion cracking (SCC) susceptibility of metals and alloys for a broad range of applications. Procedures are discussed for using the technique to (a) determine if an alloy is susceptible to SCC, (b) express SCC severity quantitatively, (c) rank alloys with respect to SCC susceptibility, and (d) evaluate the consequences of SCC susceptibility. Metallography or fractography is essential to confirm the presence or absence of SCC. Once SCC is confirmed, a number of parameters are available to express SCC severity quantitatively. Slow strain-rate technique is a conservative measure in that alloys exhibiting SCC in the test can be acceptable in service if stresses are controlled; however, no SCC in the test indicates no SCC in service under the conditions tested.

Slow Strain-Rate Stress Corrosion Testing of Aluminum Alloys
Author: EH. Gillespie
Publisher:
ISBN:
Category : Alloys
Languages : en
Pages : 12
Book Description
The use of the slow strain-rate stress corrosion technique for testing aluminum alloys is discussed. This technique is compared to the more frequently used statically loaded, alternate immersion test technique used for evaluating the susceptibility of aluminum alloys to stress corrosion cracking (SCC). Aluminum alloys (2124 and 7075), each in three conditions with differing susceptibilities to SCC, were tested by both the statically loaded alternate immersion test and the slow strain-rate technique. The results of these tests are compared and the slow strain-rate test is shown to be a viable, rapid technique for determining the SCC susceptibility of aluminum alloys.

Book Description
This document specifies the principle, test solutions, specimens, test procedures and test report of the test method for determining susceptibility to stress corrosion of steel reinforcement in simulated marine environment. This document is applicable to the test of susceptibility to stress corrosion of steel reinforcement in simulated marine environment, such as: atmospheric areas, splash areas, tidal range areas (water-level change areas) and seawater immersion areas, etc., under concrete pore fluid conditions, using constant-load uniaxially loaded tension and slow strain rate methods.

Slow-Strain-Rate Stress Corrosion Testing of Aluminum Alloys
Author: NJH Holrody

ISBN:
Category : Al-Cu-Mg
Languages : en
Pages : 40
Book Description
An extensive program of slow-strain-rate stress corrosion testing of aluminum alloys in a wide variety of susceptibility conditions and environments produced results fully consistent with the expected behavior from service experience and the results of other established test methods. Tests were conducted both on laboratory alloys in sheet form and on commercial alloys in wire, sheet, and plate forms; the systems studied included Al-Zn-Mg, Al-Zn-Mg-Cu, Al-Cu-Mg, and Al-Mg. Suitable strain rate regimes for testing, standard environments, and optimum stress corrosion susceptibility parameters were established. In general, a rate of 10-6/s was found to be appropriate for 2000 and 7000 series alloys and 10-4/s for 5000 series alloys. The most effective test environment was found to be 3% NaCl + 0.3% H2O2 for all alloys tested, and in general either relative elongation or reduction in area was the most meaningful susceptibility assessment parameter.

Languages : en
Pages : 15
Book Description
The testing of materials for stress corrosion cracking (SCC) in a use environment involves the risk that cracking may not be found by the test technique. When this happens, immunity to SCC may be incorrectly concluded. To avoid this type of error, the use of multiple testing techniques is recommended.
