New understanding could lead to significant new materials Researchers at MIT have made significant progress in understanding a class of materials that has resisted analysis for decades. Their findings could lead to the rapid discovery of a variety of useful new kinds of glass made of metallic alloys with potentially significant mechanical, chemical and magnetic applications. The first examples of metallic alloys that could be made into glass were discovered back in the late 1950s and led to a...

The new alloys are lighter and less expensive, but are still tough and ductile enough for use in aerospace applications Scientists from the California Institute of Technology (Caltech) have created a range of structural metallic-glass composites, based in titanium, that are lighter and less expensive than any the group had previously created, while still maintaining their toughness and ductility--the ability to be deformed without breaking. A paper describing these breakthrough metallic-glass...

Fluorogenic detector glows bright green when in contact with mercury and could be used onsiteResearchers at the University of Pittsburgh have developed a simple and quick method for detecting mercury in fish and dental samples, two substances at the center of public concern about mercury contamination. The technique involves a fluorescent substance that glows bright green when it comes into contact with oxidized mercury, the researchers report in the current online edition of the "Journal of...

By Kundu, S Chatterjee, S; Olson, D; Mishra, B In the present study, copper was used as an intermediate material in diffusion bonding between titanium and stainless steel. The process was carried out in the temperature range of 850 [degrees]C to 1000 [degrees]C for 60 minutes and at 900 [degrees]C for 30 to 150 minutes under the compressive stress of 3 MPa in a vacuum. The effects of temperature and time on the microstructure of Ti | Cu | stainless steel diffusion-bonded joints were...

We have no clue regarding the history, age or genre of these two peasant figures. Can you identify them? - Butrcup A: We assume the figures are fairly large - at least 18 to 24 inches tall - and will base our valuation upon that supposition. (We ask readers to send objects' exact dimensions so we can provide a more complete answer.) This pair was made from a silvery-gray metal that is rather soft and easily cast. It's primarily zinc alloyed with small amounts of one or more other...

By Gao, Michael C Dogan, Omer N; King, Paul; Rollett, Anthony D; Widom, Michael The purpose of this work is to predict elastic and thermodynantie properties of chromium-based alloys based on first-principles calculations and to demonstrate an appropriate computational approach to develop new materials for high-temperature applications in energy systems. In this study, Poisson ratio is used as a screening parameter to identify ductilizing additives to the refractory alloys. The results...

By Lee, Kyuhong Lee, Sang-Bok; Lee, Sang-Kwan; Lee, Sunghak In the present study, a Zr-based amorphous alloy matrix composite reinforced with tungsten continuous fibers was fabricated without pores or defects by a liquid pressing process; the microstructures and mechanical properties of the fibers were investigated. Approximately 60 vol pct of the fibers was distributed inside the amorphous matrix, although the matrix of the composite also contained a small number of polygonal crystalline...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
