Allegheny Ludlum Type 316Ti (UNS S31635) is a titanium stabilized version of Type 316 molybdenum-bearing austenitic stainless steel. It is also known as DIN/EN designation No. 1.4571. The Type 316 alloys are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Type 304. They also offer higher creep, stress-ru...

Corrosion, stress-corrosion cracking or corrosion-initiated fatigue significantly impact maintenance downtime and structural life limitations of aging aircraft. Both legacy and new air platforms such as the Joint Strike Fighter (JSF), realize that corrosion will likely continue to be a structural challenge that warrants a structural health management system to provide accurate, cost effective a...

Abstract The use of magnesium and its alloys as temporary implants has gained interest in the last two decades due to their good mechanical properties bio-degradability in-vivo conditions. However, issues higher corrosion rate stress cracking persist, which are responsible for implants’ early failure. This review paper focuses on challenges involved magnesium-based advancements mitigating corro...

The models of stress corrosion and pressure solution established by Yasuhara et al. were introduced into the 2D FEM code of thermo-hydro-mechanical-migratory coupling analysis for dualporosity medium developed by the authors. Aiming at a hypothetical model for geological disposal of nuclear waste in an unsaturated rock mass fromwhich there is a nuclide leak, two computation conditions were desi...

Failures of structural and mechanical components have long been attributed to environmentally assisted cracking (EAC). The umbrella of EAC encompasses several phenomena, including stress corrosion cracking (SCC), corrosion fatigue (CF), hydrogen embrittlement (HE) and liquid metal embrittlement (LME). The latter, LME, has resulted in the failure of components in petrochemical and aeronautical i...

The present review is intended to revisit the advances and debates in the comprehension of the mechanisms of subcritical crack propagation in silicate glasses almost a century after its initial developments. Glass has inspired the initial insights of Griffith into the origin of brittleness and the ensuing development of modern fracture mechanics. Yet, through the decades the real nature of the ...

A progress report of the ret arch invest carried out on the problem of stress-cor high strength materials under ARPA Order Work at Carnegie-Mellon University, Lehi Georgia Institute of Technology, The Boe American University, and the Naval Resea cerning test techniques, materials chara metallurgy, surface studies, and corrosi described. The report is divided into t covering work on high strengt...

In this work, Slow Strain Rate Test (SSRT) testing, Light Optical Microscopy (LOM) and Scanning Electron Microscopy (SEM) were used to study the effect of microstructure, corrosive environments and cathodic polarisation on stress corrosion cracking (SCC) of two grades of high strength steels, Type A and Type B. Type A is manufactured by quench and tempered (Q&T) method. Type B, a normalize stee...
