A set of scaling laws has been developed for describing intermittent as well as continuous
fatigue crack growth of large cracks in steels in the power-law regime. The proposed scaling …

Fatigue mechanisms of large and small cracks in Cu-bearing HSLA-80 steels were studied
at ambient temperature. Fatigue striations were measured for both large and small fatigue …

This article describes the types of closure mechanisms, including plasticity-induced,
roughness-induced, oxide-induced, and fretting-debris-induced. It discusses test techniques …

Welding overlay repair (WOR) is commonly employed to rebuild piping systems suffering
from intergranular stress corrosion cracking (IGSCC). To understand the effects of this repair …

Near-threshold corrosion fatigue crack propagation studies have been conducted using
compact tension specimens of Mil S-24645 HSLA steel and a compatible weld metal in air …

The goal of the subject program is to develop fundamental understandings of the
relationships between microstructure and fatigue damage in structural steels of interest to …

The effects of crack closure on the near-threshold corrosion fatigue crack growth behavior of
Mil S-24645 HSLA steel and its weld metal have been investigated in air, ASTM seawater at …

A new method for accelerating the collection of near‐threshold corrosion fatigue crack
propagation data, using local hydrogen embrittlement in the crack tip region, has been …

The near-threshold corrosion fatigue crack propagation behavior of Mil S-24645 HSLA steel,
its weld metal and heat-affected zone have been studied in simulated marine environments …

A survey of recently published, mainly experimental, results on the near-threshold fatigue
crack behavior of metallic materials is presented. An attempt is made to analyze and …
