Book Description
Forged parts and billets of AISI 4340, H11 tool steel, and 9% and 18% nickel alloy steels were evaluated for susceptibility to stress corrosion cracking (SCC) by an alternate immersion test. The alloys were prepared by the consumable electrode-vacuum melt practice and were heat treated as test specimens to strengths in the range from 263,000 to 290,000 psi. Polished specimens were alternately immersed in a 5% NaCl solution while sustaining a load equivalent to 75% of the ultimate strength.

Book Description
The problem of stress corrosion cracking (SCC), which causes sudden failure of metals and other materials subjected to stress in corrosive environment(s), has a significant impact on a number of sectors including the oil and gas industries and nuclear power production. Stress corrosion cracking reviews the fundamentals of the phenomenon as well as examining stress corrosion behaviour in specific materials and particular industries.The book is divided into four parts. Part one covers the mechanisms of SCC and hydrogen embrittlement, while the focus of part two is on methods of testing for SCC in metals. Chapters in part three each review the phenomenon with reference to a specific material, with a variety of metals, alloys and composites discussed, including steels, titanium alloys and polymer composites. In part four, the effect of SCC in various industries is examined, with chapters covering subjects such as aerospace engineering, nuclear reactors, utilities and pipelines.With its distinguished editors and international team of contributors, Stress corrosion cracking is an essential reference for engineers and designers working with metals, alloys and polymers, and will be an invaluable tool for any industries in which metallic components are exposed to tension, corrosive environments at ambient and high temperatures. - Examines the mechanisms of stress corrosion cracking (SCC) presenting recognising testing methods and materials resistant to SCC - Assesses the effect of SCC on particular metals featuring steel, stainless steel, nickel-based alloys, magnesium alloys, copper-based alloys and welds in steels - Reviews the monitoring and management of SCC and the affect of SCC in different industries such as petrochemical and aerospace

Book Description
Low alloy quenched and tempered steels used in current Naval aircraft applications, particularly the ultrahigh strength steels used in landing gear, have characteristically small critical flaw sizes and extreme susceptibility to stress corrosion cracking in a shipboard environment. Newly developed steels which develop ultrahigh strengths with secondary hardening based on precipitation of M2C carbides offer significantly larger critical flaw sizes; and while susceptible to stress corrosion cracking, their susceptibility is substantially less than that of low alloy steels. A long term test program conducted by the Naval Air Warfare Center Aircraft Division Warminster has characterized the stress corrosion cracking susceptibility of the newly developed steels. Results of the program have shown that, compared to low alloy steels, the newly developed steels show substantially reduced susceptibility to stress corrosion at short exposure times and maintain their advantage to a lesser extent at exposure times up to 1 0,000 hours. The test program has demonstrated also that 1,000 hour exposure times, characteristically used for stress corrosion tests of steels, are insufficient to establish stress corrosion thresholds (Klscc), as numerous failures were observed at exposure times between 1,000 and 1 0,000 hours. Fracture characteristics of the stress corrosion failures are shown.
