The fatigue crack nucleation mechanism of Ti-2Al-2.5 Zr alloy was investigated using the
coupling method of quasi in-situ tests with crystal plasticity (CP) simulation. The constitutive …

FeCoCrNi, a high-entropy alloy fabricated by laser powder bed fusion, has excellent room-
temperature mechanical properties but poor high-temperature mechanical performance. To …

Fatigue cracks in additively manufactured (AMed) Inconel 718 (IN-718) in machined surface
condition often initiate from persistent slip bands (PSBs) unlike other popular AM alloys such …

Metallic materials are widely employed in engineering constructions, and one of the most
common failure mechanisms in metals is fatigue failure. Even though metal fatigue has been …

Intergranular fatigue crack nucleation has been reported to occur commonly at high angle
grain boundaries (HAGBs) but seldom at low angle GBs (LAGBs) during persistent slip band …

Polycrystalline copper specimens were fatigued in strain-controlled regime with high and
low strain amplitude. Stress amplitude, plastic strain amplitude and hysteresis loops were …

The multiaxial low cycle fatigue behavior of nickel-based alloy 690 at 350° C was
investigated. The multi-slip planar dislocation configuration under non-proportional loading …

Laser directed energy deposition (DED) offers significant advantages for the integral
manufacturing of large-scaled thin-walled workpieces. Nevertheless, how to improve the …

Additively manufactured (AM) materials are prone to porosity, which limits their widespread
adoption in fatigue-limited applications. Experimental campaigns are vital in understanding …

How to remarkably elevate the high-cycle fatigue resistance of metallic materials under
cyclic loading is a crucial, yet technically challenging issue for major structural applications …
