Effect of fibrous macrostructure on mechanical properties, anisotropy and fracture mechanism of roller bearing ring

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2021
The fabrication of bearing ring with reasonable fibrous macrostructure is necessary to enable long-service period in aero-engine. This investigation demonstrates a forging method to improve fibrous macrostructure distribution via a low height-diameter ...

Macrostructure in narratives produced by Lebanese Arabic-French bilingual children

Linguistic Approaches to Bilingualism, 2021
Studies of macrostructure in bilingual children investigated potential age and language effects, without systematically taking into account bilingualism factors such as language dominance, exposure to narratives, and general language abilities.

How do age, language, narrative task, language proficiency and exposure affect narrative macrostructure in German-Swedish bilingual children aged 4 to 6?

, 2021
Previous studies show mixed findings concerning whether higher-order story structure (macrostructure) is similar across bilinguals’ two languages. It is not known how macrostructure is influenced by general language proficiency and amount of exposure.

Macrostructure, microstructure and mechanical properties evolution during 8Cr4Mo4V steel roller bearing inner ring forging process

Materials Science & Engineering: A, 2020
Hot ring rolling (HRR) is an advanced partial progressive forming technology that can directly manufacture various sizes of precision bearing rings. How to prefabricate the ring blank will affect the utilization rate of materials, flow lines distribution

Evaluation of macrostructural bone biomechanics

Joint Bone Spine, 2007
Bone fragility can be defined as an increased risk of fractures. Advanced age and bone diseases such as osteoporosis increase the fracture risk. Understanding the effects of osteoporosis and its treatments requires a description of the mechanical behavior of bone tissue.

Adsorption of Eu(III) and Th(IV) on three-dimensional graphene-based macrostructure studied by spectroscopic investigation.

Environmental Pollution, 2019
One of the most important reasons for the controversy over the development of nuclear energy is the proper disposal of spent fuel. Separation of actinide and lanthanide ions is an important part of safe long-term storage of radioactive waste.

Macrostructure

1984
Abstract This chapter describes several macroscopic examination techniques, including macroetching, contact printing, fracturing, and lead exudation. It explains how each method is implemented, why it is used, and what it reveals about manufacturing processes, defects, imperfections, and failure mechanisms.
