Abstract Bioinspired architectures are effective in enhancing the mechanical properties of materials, yet difficult to construct metallic systems. The structure-property relationships bioinspired composites also remain unclear. Here, Mg-Ti were fabricated by pressureless infiltrating pure Mg melt into three-dimensional (3-D) printed Ti-6Al-4V scaffolds. result was composite materials where constituents continuous, mutually interpenetrated 3-D space and exhibit specific spatial arrangements...
Enhancing the fatigue strength of materials by increasing their tensile is generally considered as an effective strategy. This study observed a plateau in TC11 alloy: despite significant variations strength, alloy demonstrates remarkable stability. It determined that this anomalous behavior governed unique cracking mechanism associated with primary α phase (α p ) dual‐phase titanium alloys due to pilling‐up dislocations and consequent cleavage (pillingup‐cleavage). Under mechanism, critical...
It is a great challenge to improve the strength of disc superalloys without loss plasticity together since microstructures benefiting always do not avail plasticity. Interestingly, this study shows that trade-off relationship between and can be broken through decreasing stacking fault energy (SFE) in newly developed Ni-Co based superalloys. Axial tensile tests temperature range 25 725 °C were carried out these alloys with Co content ranging from 5% 23% (wt.%). found ultimate (UTS) uniform...
Tensile and low-cycle fatigue tests of high-strength compacted graphite cast iron (CGI, RuT450) were carried out at 25 °C, 400 500 respectively. The results show that with the increase in temperature, tensile strength decreases slowly then rapidly. life decreases, reduction increases high temperature strain amplitude. oxide layer appears around cracks dependence crack propagation on ferrite gradually decreases. With amplitude, initial cyclic stress three temperatures, hardening phenomenon is...
Abstract The evolution of natural armor materials has led to gradient structures with specific architectures achieve high damage tolerance, thus offering valuable inspiration for the design man‐made materials. Here, bioinspired composites a nacre‐like brick‐and‐mortar architecture are fabricated by infiltrating polymer phase into porous ceramic scaffolds position‐specific content. These demonstrate an integrated structure notable several‐fold variations in local hardness and modulus across...
The low-cycle fatigue (LCF) cracking behavior in various face-centered-cubic (fcc) crystalline materials, including Cu single crystals, bicrystals and polycrystals, Cu–Al Cu–Zn alloys, ultrafine-grained (UFG) Al–Cu was systematically investigated reviewed. In always nucleates along slip bands deformation bands. large-angle grain boundary (GB) becomes the preferential site polycrystals. addition, can also nucleate twin boundaries (TBs) polycrystalline materials. However, shear coarse are...
ABSTRACT The microstructural characterizations, micro‐hardness measurements and fatigue tests of B1500HS steel spot welded tensile‐shear specimens were performed. high hardness values base material (470 HV) nugget (515 are closely related to the dominant formation martensitic microstructures, while occurrence soft zone is result ferrite phases in inter‐critical heat‐affected (HAZ), as well martensite tempering sub‐critical HAZ. failure modes involve fracture along circumference or direction...
Based on the models of series and parallel connections two phases in a composite, analytic approximations are derived for elastic constants (Young's modulus, shear Poisson's ratio) elastically isotropic two-phase composites containing second various volume fractions, shapes, regular distributions. Comparison with plentitude finite element simulations numerous previous experimental investigations shows large consistency between results expressions derived, confirming adequacy present...
The occurrence of deformation twinning in face-centered-cubic (fcc) crystals with medium to high stacking fault energy is normally very difficult. Through specially designing the orientation Cu single crystal, authors do not only observe profuse nanoscale twins a tower shape originating from grain boundary but also find some them terminated interior grain. observations clearly prove that can nucleate through successively emitting partials boundaries, indicating ubiquity even those fcc...
The cyclic deformation behaviour of polycrystalline Cu, Cu–10 wt% Zn and Cu–32 was systematically investigated in the plastic strain amplitude range 1 × 10−4–4 10−3. differences stress–strain (CSS) responses fatigue cracking between were compared. It found that occurrence a saturation for strongly depends on applied amplitude, whereas Cu always displays saturation. Surface morphologies analyzed by scanning electron microscopy (SEM). One major features observed is slip bands become...
