Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

open access: yesAdvanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

HISTORY, ORGANIZATION AND STRATEGIES FOR GRAIN PRODUCERS AND THE GRAIN INDUSTRY IN MICHIGAN

open access: yes
The grain system (grain producers and the grain industry) in Michigan finds itself in a transition period. Production (yield) and price limitations along with escalating cost factors have left producers in a situation where, without government assistance,

The Effects of the Micro-Market Structure for Kansas Grain Elevators on Spatial Grain Price Differentials

open access: yes
Corn and wheat cash prices in Kansas are affected by a number of local supply-demand, market structure, transportation access and other factors. Kansas corn prices in 2008 were affected by form of business organization, local feedgrain production and ...

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Structural Change and Performance of Grain Marketing Cooperatives

open access: yes
The U.S. grain marketing system has undergone many structural changes in the 1980s. In no part of the system has structural change been more far-reaching and extensive than in farmer-owned cooperatives.
