Part-through fracture toughness (K) and crack-tip opening displacement (CTOD) of welded joints of AA2014-T6 at low temperatures

Cryogenics, 2015
Abstract The part-through fracture toughness ( K Ie ) and crack-tip opening displacement (CTOD, δ m ) of welded joints of aluminum alloy (AA) 20l4-T6, including the weld metal, the fusion zone (FZ), the heat-affected zone (HAZ), and the base material, were investigated at both liquid nitrogen temperature and liquid helium temperature with surface ...

Effects of Ni and Mn addition on critical crack tip opening displacement (CTOD) of weld-simulated heat-affected zones of three high-strength low-alloy (HSLA) steels

Materials Science and Engineering: A, 2017
Abstract In order to understand and improve fracture toughness of heat affected zones (HAZs) of high-strength low alloy (HSLA) steels, complex microstructures including quasi-polygonal ferrite (QPF), acicular ferrite (AF), granular bainite (GB), bainitic ferrite (BF), and martensite-austenite (MA) constituent should be identified, quantified, and ...

Crack Tip Opening Displacement (CTOD) Toughness Evaluation by ASTM E 1290 and BS5762: A Comparative Analysis

Journal of Testing and Evaluation, 1992
Abstract ASTM Committee E-24 on Fracture has recently standardized the crack tip opening displacement (CTOD) measurement method. Three major differences between the ASTM E 1290-89 method and British Standard BS5762:1979 are outlined, and the influence of these differences on the critical crack initiation CTOD value is studied.
