Engineers achieve longstanding goal of stable nanocrystalline metals
Tongjai Chookajorn, left, and Heather Murdoch, the lead authors of Science paper on the design and production of new stable nanocrystalline metal alloys with exceptional strength and other...
View ArticleCracked metal, heal thyself
It was a result so unexpected that MIT researchers initially thought it must be a mistake: Under certain conditions, putting a cracked piece of metal under tension — that is, exerting a force that...
View ArticleA window to the art of classical manufacturing science
MIT's Glass Lab and the Forge and Foundry spaces will close after graduation on June 6 for major renovations. These renovations will serve more students and provide better space for the popular...
View ArticleShedding light on the future of photovoltaics
Several government agencies, academic researchers, and firms have proposed scenarios for the future in which photovoltaic (PV) technologies grow rapidly. To support such growth, PV technologies would...
View ArticleAlloying tougher tungsten
New tungsten alloys being developed in the Schuh Group at MIT could potentially replace depleted uranium in armor-piercing projectiles. Fourth-year materials science and engineering graduate student...
View ArticleA renaissance in metals
A renaissance is underway in materials science, and especially in metals design, fabrication, and characterization, says MIT Materials Processing Center Director Carl V. Thompson.“No longer are...
View ArticleMaterials Processing Center marks 35 years
The Materials Processing Center (MPC) celebrates 35 years of service to the MIT faculty and materials research community during 2015. Current MPC research topics include synthesis of materials for...
View ArticleNew metal alloys overcome strength-ductility tradeoff
For centuries — in fact, since the Bronze Age began some 7,000 years ago — the creation of new metallic alloys has mostly been a trial-and-error process. Traditionally, one metal constituent was always...
View ArticleMetals aficionado
“Metal production is like cooking,” says C. Cem Tasan. “Sometimes you try to optimize a recipe and find new ingredients to bring in, and sometimes you have a crazy idea — like adding orange to chicken...
View ArticleAgitating the aluminum pot
Industrial aluminum slabs are typically produced by blending small amounts of copper or manganese in a reservoir of molten aluminum that is rapidly cooled, a process known as direct-chill casting....
View ArticleMotivated by the thrill of discovery
There are many kinds of frustration. There’s the kind of frustration of electrons in some materials at extremely low temperatures that forces them to abandon their preference for classical states such...
View ArticleConquering metal fatigue
Metal fatigue can lead to abrupt and sometimes catastrophic failures in parts that undergo repeated loading, or stress. It’s a major cause of failure in structural components of everything from...
View ArticleEnvisioning the future of metal and mineral production
Metals and minerals form the base of our society, with diverse applications infiltrating all corners of our lives, including agriculture, infrastructure, transportation and information technology. As...
View ArticleFeatured video: Making medallions
Each year, the MIT Department of Materials Science and Engineering (DMSE) presents its new graduates — roughly 100 undergraduate and graduate students — with a bronze medallion of the MIT seal. These...
View ArticleLiquid tin-sulfur compound shows thermoelectric potential
Glass and steel makers produce large amounts of wasted heat energy at high temperatures, but solid-state thermoelectric devices that convert heat to electricity either don’t operate at high enough...
View ArticleA new way of extracting copper
MIT researchers have identified the proper temperature and chemical mixture to selectively separate pure copper and other metallic trace elements from sulfur-based minerals using molten electrolysis....
View ArticleChemists discover unexpected enzyme structure
Many microbes have an enzyme that can convert carbon dioxide to carbon monoxide. This reaction is critical for building carbon compounds and generating energy, particularly for bacteria that live in...
