In this study, high cycle fatigue behavior of Ti6Al4V ELI alloy with bimodal microstructure was studied and its correlation with crack initiation was investigated. The results show that fatigue crack mainly initiated at subsurface or interior of the tested specimens. Fatigue life generally increases with increasing crack initiation site-specimen surface distance under same/similar stress level. The maximum stress level shows big influence on the locations of crack initiation sites. Higher maximum stress could lead the crack initiation site to an inner position within fatigue specimen, which can be attributed to the strengthening of necking effect. Based on analyses, the influence of maximum stress on the probability of different crack initiation modes was summarized. By comparing the calculation results, the fatigue specimens with interior crack initiation mode have obviously higher threshold stress intensity factor range than other modes, which indicates higher resistance to fatigue crack propagation. Besides, it was found that the fracture surface morphology of fatigue specimens contains three features, including initiation facet, propagation facet, and rough surface with tear ridges.

The results show that the crack extension process takes place in a discontinuous manner that resolves into two steps: First, grain-sized microcracks form in the basal planes of crack-tip grains; second, the microcracks coalesce with the main crack by local ductile fracture along grain boundaries and twin boundaries in between the cracks. The activity of deformation twinning is low at the crack tip. Analysis of resolved shear stress suggests that the formation of microcracks is associated with high basal slip activity poorly compensated by other deformation systems.

This review provides a comprehensive analysis of advanced low-power FETs, focusing on semiconductor materials, architectures, fabrication techniques and applications. Emerging materials such as 2D semiconductors, IGZO (indium gallium zinc oxide), TMDs (transition metal dichalcogenides) and III–V compounds play a pivotal role in enabling innovative FET topologies like FinFETs, stacked nanosheet FETs (NSFETs), vertical NSFETs, TreeFETs and complementary FETs. These materials, with superior properties such as high-mobility channels, improved scalability and energy efficiency, are critical in overcoming the challenges posed by conventional CMOS technology node scaling. In particular, NSFETs are anticipated to substitute the state-of-the-art nanowire FET and FinFET devices due to their ability to provide better electrostatic control and tunable channel widths. This transition is expected to reshape the semiconductor technology in the years ahead. A critical aspect of integrating these architectures lies in the advanced fabrication steps such as epitaxial growth techniques, spacer-based lithography and high-k metal gate (HKMG) integration that enables precise control over device dimensions and enhancing performance. These innovations facilitate the integration of advanced architectures for diverse applications including logic circuits, memory devices including SRAM, MRAM, sensing technologies and RF applications.
