Initial cutting conditions by abrasive grain fixed flexibly

The International Journal of Advanced Manufacturing Technology, 2008
In the paper, the initial cutting conditions by an abrasive grain fixed flexibly have been described. These conditions have been determined by incision angle at the beginning of machining zone as well as the occurring phenomena resulting from a mechanical cooperation of abrasive grain with machined material. It has been revealed that the incision angle

A thermokinetic description of nanoscale grain growth: Analysis of initial grain boundary excess amount

Scripta Materialia, 2010
A thermokinetic description was performed for nanoscale grain growth by analyzing the effect of grain boundary (GB) segregation on the initial GB excess amount, Γ b . Compared with the model assuming a linear relation between Γ b and grain size (i.e. Γ b Γ b0 , the saturated value) [Chen et al., Acta Mater.

Short‐term market impact of Black Sea Grain Initiative on four grain markets

Journal of Futures Markets
AbstractThis paper examines the short‐term market reaction of four agricultural commodities to the Russian–Ukraine war and various stages of the Black Sea Grain Initiative Agreement. Using an event study, the results show a positive abnormal return for the agricultural grain markets with the outbreak of the war and the nonrenewal of the Black Sea Grain

Grain Growth in Films with Initial 3D Microstructure

Materials Science Forum, 2004
Grain growth in films with h/〈D〉0=3.5−7.5, where h is the film thickness and 〈D〉0 the initial average grain diameter, was studied by means of computer simulation. The growth kinetics during 3D®2D microstructure transformation do not obey the parabolic law commonly used for the grain growth description.

Fatigue crack initiation life of fine grain brass H62

Theoretical and Applied Fracture Mechanics, 2010
Fine grain alloys possess excellent properties entailing high strength and toughness. Fine brass H62 is made by re-crystallization with grain size ranging from 5 to 10 μm. Fatigue initiation life is investigated from specimens tested on Instron 1341 machine a frequency of 30 Hz.

Against the Grain: Capability Renewal through Contested Initiatives

2014
This work in progress paper aims to contribute to the literature on the cognitive foundations of capability development. Extant research acknowledges that capabilities are rooted in taken for granted conventions that are both a source of distinctiveness but may potentially also give rise to capability level rigidity.
