Forge and Heat-treatments in Microalloyed Steels – A Review
High Temperature Materials and Processes, 2013 Improved designs, mostly for lightweight component manufacturer, have been made for improvement of forging and heat-treatment techniques. Low temperature precipitation strengthening and resistance to austenite grain size coarsening at reheat temperature ...

Journal of the Society of Materials Science, Japan, 2006 Equal channel angular pressing (ECAP) invented by Segal was applied successfully to metal process of aluminum and magnesium alloys for increasing their strength by fining the grain size. But a little attention has been paid to its application to polymers.

Temporary Programs, Lasting Questions: Ad Hoc Assistance in the U.S. Farm Safety Net
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Large ad hoc assistance programs have returned to U.S. farm policy since 2017, operating alongside a more developed safety net built around federally subsidized crop insurance, Title I commodity programs, and standing disaster assistance. This paper reviews the renewed use of ad hoc assistance, documents its recent scale using USDA data, and ...

On the Effect of Natural Aging Prior to Low Temperature ECAP of a High-Strength Aluminum Alloy
Metals, 2018 Severe plastic deformation (SPD) can be used to generate ultra-fine grained microstructures and thus to increase the strength of many materials. Unfortunately, high strength aluminum alloys are generally hard to deform, which puts severe limits on the ...

AIChE Journal, EarlyView.Abstract Nanofluids containing nanoparticles represent a promising solvent or reaction system for gas–liquid operations. Herein, the effect of nanoparticle (Al2O3 and SiO2) addition on gas–liquid slug flow pattern and mass transfer enhancement was investigated during CO2 absorption into water in microreactors.

Superplastic Behavior of AZ31 Processed by ECAP
Procedia Materials Science, 2015 AbstractMagnesium base alloys have reached an important development as structural materials the last years due to its good strength/weight relationship. On the other hand, superplastic forming has also acquired a technological interest in the last time, due to the possibility of achieving complex geometries in only one forming step, with competitive ...

Journal of Applied Crystallography, EarlyView.We present an improved numerical angle‐dependent absorption correction procedure for line‐collimated small‐ and wide‐angle X‐ray scattering measurements in thin‐walled quartz capillaries. The procedure accounts for the constrained illuminated volume, measured primary beam profiles and capillary‐wall absorption, enabling physically consistent data ...
