TL;DR: In this article, the authors investigated the fatigue crack growth rate in ultrafine grained (UFG) Al-7.5Mg and compared it to powder-metallurgy (P/M) Al−7Mg, ingot-mechanical (I/M), and I/M Al−6Mg.

TL;DR: In this article, it was shown that the severity of the strain on the crack-grind ratio is related to range and maximum values of the stress-intensity factor.
Abstract: REGRESSION MODELS, BASED ON LINEAR ELASTIC FRACTURE MECHANICS, ARE USED TO INTERPRET THE EFFECT OF STRESS RATIO ON FATIGUE CRACK GROWTH RATE IN 7075-T6 ALUMINUM ALLOY. IT IS SHOWN THAT FATIGUE CRACK GROWTH RATE CAN BE RELATED TO RANGE AND MAXIMUM VALUES OF STRESS-INTENSITY FACTOR. STATISTICAL TECHNIQUES ARE USED TO EXAMINE THE ERROR WHICH MAY ACCUMULATE WHEN REGRESSION EQUATIONS ARE USED TO PREDICT CRACK GROWTH VERSUS CYCLES CURVES. /ASTM/

Journal ArticleDOI
TL;DR: In this paper, the effects of short-fiber/particle hybrid reinforcement on fracture toughness and fatigue crack growth in metal matrix composites were studied, and the positive aspect of particulate reinforcement was advocated by comparison of microstructural variables, and by observation of the crack path and surfaces.

Journal ArticleDOI
TL;DR: In this paper, the specific effect of microstructural similitude on the crack driving force of both small and short, versus large, cracks is examined, and its relevance to small crack behavior illustrated by considering the dependence of the number of grains interrogated by the crack front on crack size and resulting yield strength variation within the crack tip process zone.

TL;DR: In this paper, the effects of crack growth direction on the fatigue crack growth of wire arc additive manufactured Ti-6Al-4V were studied, and the results showed that the FCGR of vertical sample is 5% higher than that of horizontal sample when the stress intensity factor, ΔK is smaller than ΔKT.
Abstract: The effects of crack growth direction on the fatigue crack growth of wire arc additive manufactured Ti-6Al-4V were studied. The fatigue crack growth rate (FCGR) of horizontal and vertical samples has different stress intensity factor transition point, ΔKT, which is 11.3 MPa m1/2 and 10.3 MPa m1/2, respectively. The FCGR of vertical sample is 5% higher than that of horizontal sample when the stress intensity factor, ΔK is smaller than ΔKT. The difference in FCGR is resulted from the microstructure characterization and the fatigue crack growth direction.
