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...
Molecular Dynamic (MD) simulations were used to investigate the tensile properties of nanocrystalline Ni–Al series Ni-based superalloy at different grain sizes (6.54–20 nm), strain rates (1 × 107–5 108 s−1) and temperatures (300–1000 K). Results indicate that plastic deformation was governed by stacking faults FCC-to-HCP martensitic phase transformation, which significantly from twinning-dominated in Ni. Nevertheless, conventional Hall-Petch breakdown occurred a critical size both Ni...
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,...
Carbon allotropes occupy significant roles in heat conduction fields. The thermal transmission most is determined by phonons, and ultimately, fundamentally dependent on the properties of chemical bonds. In this paper, four novel 2D carbon has been studied, including penta-graphene, Ψ-graphene, pop-graphene net-W using non-equilibrium molecular dynamic (NEMD) simulations time domain normal mode analysis (TDNMA). Graphene, standard allotrope, also examined for comparison. Our NEMD simulated...
In this work, a weld metal in K65 pipeline steel pipe has been processed through self-designed post-weld heat treatments including reheating and tempering associated with hot bending. The microstructures the corresponding toughness microhardness of subjected to have investigated. Results show that increase temperature, austenite grain size increases main transition from fine polygonal ferrite (PF) granular bainitic (GB). density high angle boundary decreases at higher leading loss impact...
