Criteria of Grain Refinement Induced by Ultrasonic Melt Treatment of Aluminum Alloys Containing Zr and Ti [PDF]

, 2010
It is well known that ultrasonic melt treatment (UST) promotes grain refinement in aluminum alloys. Cavitation-aided grain refinement has been studied for many years; however, it is still not being applied commercially. The current article summarizes the

Heterogeneous Exhumation Mechanisms in Neoproterozoic Collisional Metamorphism: P–T Constraints From Pelotas and Punta del Este Terranes, Southern Brazil and Uruguay

Geological Journal, EarlyView.
Petrography, thermobarometry, and pseudosection modelling reveal peak metamorphic conditions of 3–7.5 kbar and 520°C–800°C in Tonian‐Cryogenian orthogneisses of the Dom Feliciano Belt. Metamorphic field gradients of 27°C/km–39°C/km and variable exhumation mechanisms support correlation of these units as remnants of a Himalayan‐type Piratini Orogeny ...

Aluminum silicates in the Prince Olav and Soya Coasts, East Antarctica [PDF]

, 1983
P(論文)This paper presents the regional distribution and textural features of aluminum silicates (kyanite, sillimanite, and andalusite) in the Prince Olav and Soya Coasts, East Antarctica. The data make it clear that the regional metamorphism in the region,

Layer silicates in a chondritic porous interplanetary dust particle

, 1985
Analytical electron microscopy on individual grains from a portion of a chondritic porous interplanetary dust particle (aggregate W7029C1 from the NASA Johnson Space Center Cosmic Dust Collection) shows that layer silicates compose 50 percent of the ...

Soil Silicon Application Alleviates Drought Stress in Sugar Beet (Beta vulgaris L.)

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: The increasing frequency and intensity of drought events have led to yield and quality losses in sugar beet production in temperate regions in Central Europe. Under arid conditions, silicon (Si) application reduced beet yield losses under drought. Similar data for temperate climates are missing.

Potential for using belite sludge from the Achinsk Alumina Refinery to reduce the carbon footprint of aluminum production

Горные науки и технологии
Certain types of waste from mining and metallurgical industry have the potential to directly absorb carbon dioxide (CO2) from the atmosphere, as some of them contain minerals capable of carbonation.

Protective Effects of Er:YAG Laser and PRG Pro‐Care Gel on Enamel Demineralization

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objectives Bioactive surface pre‐reacted glass‐ionomer (S‐PRG) technology and high‐power laser irradiation have been investigated as promising preventive approaches. S‐PRG particles exhibit multifunctional bioactive glass properties, with the ability to release and recharge ions.
