Understanding the Stochastic Nature of Process Parameter Development of Blown Powder Laser Beam Directed Energy Deposition Additive Manufacturing of Pure Molybdenum

open access: yesAdvanced Engineering Materials, EarlyView.
Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

The Effect of Eggshell Quality on Hatchability of Pure Chicken Breeds

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
Hatchability is affected by a variety of factors. Eggshell quality plays very important role among these factors. In this work we analysed eggshell quality, hatchability and embryonic mortality of pure chicken breeds New Hampshire, Oravka, Plymouth Rock,

Robust Spot Melting by 3D Spot Arrangements in Electron Beam Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
This work proposes an approach to replace separately melted contours for spot melting in electron beam powder fusion. Adapting the spot arrangements close to the contour combined with stacking yields a comparable surface quality without the inherent challenges of separate contours, as demonstrated, by electron optical images and roughness measurements.

The Effect of Altitude on the Hatchability of Chicken Eggs ,

open access: yesPoultry Science, 1967
Abstract DURING the past 20 years, there has been a great reduction in the number of hatcheries in the Western Region of the United States. As a result, hatcheries which remain have become located at places which have been chosen without regard for the altitude of the area. Thus, eggs must be produced at the hatchery location or shipped in from other

Multimodal Data‐Driven Microstructure Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Hatchability and Chick Mortality

open access: yesPoultry Science, 1921
Abstract Recent studies 1 of the causes and inheritance of variations in the hatching quality or hatchability of the eggs of the domestic fowl have indicated rather definitely 1 that differences in the hatchability of eggs are determined by innate differences in the individual hens which lay them 2 that these differences are probably inherited 3 ...

Effect of Terramycin and Vitamin B12 on Hatchability.

open access: yesExperimental Biology and Medicine, 1952
SummaryAn experiment was conducted with White Leghorn pullets to determine the effect of feeding terramycin alone and in combination with vit. B12 on egg production and hatchability. The results obtained indicate that terramycin had little or no effect on egg roduction and gain in weight. In the absence of vit.

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

open access: yesAdvanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

Low Cycle Repetitive Loading of Ti‐6Al‐4V‐Epoxy Composite Lattice Structures for Enhanced Energy Dissipation and Damage Tolerance

open access: yesAdvanced Engineering Materials, EarlyView.
Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...
