Abstract Evaluating and understanding the effect of manufacturing processes on creep performance in superalloys poses a significant challenge due to intricate composition involved. This study presents machine‐learning strategy capable evaluating heat treatment process predicting rupture life with high accuracy. approach integrates classification regression models domain‐specific knowledge. The physical constraints lead significantly enhanced prediction accuracy models. Moreover, is evaluated...
In this paper, the wear behavior of M42 high speed steel (HSS) cutting tools containing rare earth elements has been investigated to reveal role carbides with diverse sizes in HSS. A map and damage mechanism for HSS have established. Based on magnitude rates, can be divided into three regions: mild wear, medium severe wear. As contact stress sliding velocity increase, evolves through stages: initial slight scratching fewer microvoids from detachment small‐sized carbides, followed by...
Cold expansion technology has been widely used in aviation industries as an effective method of improving the fatigue performance fastener holes. It can improve life several times over without adding weight, meeting growing demand for lightweight and durable aircraft structures. In recent years, it extensively studied through extensive experiments finite element simulations to analyze residual stresses around hole. Appropriate process parameters lead generation beneficial that influence...
This study aims to present the optimum technological parameters of hot forging process aerospace bolts. Deformation-related were determined according relevant conditions for commercial production Deformation behavior and evolution microstructure Waspaloy systematically studied at temperature in range 1000–1120 °C strain rate 0.01–10 s−1. The obtained results revealed sensitivity flow stresses deformation increased when deformed lower temperatures or higher rates. At high rates 5–10 s−1,...
Abstract A new kind of decagonal quasicrystal (DQC) with a periodicity 1.23 nm was observed in the as-cast quaternary Al 60 Cr 20 Fe 10 Si alloy. The intensity distribution some spots selected-area electron diffraction pattern along tenfold zone axis found to be different from other Al-based DQCs. High-angle annular dark-field scanning transmission microscopy adopted reveal structural features at an atomic level. Both symmetry and symmetry-broken (D) clusters 1.91 diameter were found, but...
Abstract A high-angle annular dark field scanning transmission electron microscopy study of the intermetallic compound Al 74 Cr 15 Fe 11 reveals a quasiperiodic structure significantly differing from ones known so far. In contrast to common quasi-unit-cells based on Gummelt decagons, present is related covering formed by Lück which can also be described Hexagon-Bow-Tie tiling.

Recently, Co–Cr–Ni medium-entropy alloys (MEAs) have garnered significant attention in the materials field owing to exceptional properties. However, various mechanisms of transformation induced plasticity (TRIP) and twinning (TWIP) effects with variation chemical compositions, strain rates, temperature grain size polycrystalline MEAs remains challenging. By utilizing molecular dynamics simulations, uniaxial tensile deformation MEAs, including equiatomic CoCrNi, non-equiatomic Co10(CrNi)90,...
Abstract By means of atomic-resolution high-angle annular dark-field scanning transmission electron microscopy, we found three types giant approximants decagonal quasicrystal in Al-Cr-Fe-Si alloys, where each type contains several structural variants possessing the same lattice parameters but different crystal structures. The projected structures these along pseudo-tenfold direction were described using substructural blocks. Furthermore, relationship and plane crystallographic groups (a, c)...
