RESEARCH TRIANGLE PARK, N.C. A U.S. Army project discovery upends previous notions about how metals deform and could help guide the creation of stronger, more durable materials for military vehicles.

Researchers at the University of Wisconsin-Madison, funded by the Army Research Office, discovered a new mechanism for bending, published in Nature Communications, that might allow engineers to strengthen a material without running the risk of fractures.

Currently, engineers manipulate the strength of a metal through techniques such as cold working or annealing, which exert their effects through small structural irregularities called dislocations. Strengthening techniques typically restrict the motion of dislocations.

Researchers have since discovered samarium cobalt, known as an intermetallic, that bends easily, even though its dislocations were locked in place. According to the research, bending samarium cobalt caused narrow bands to form inside the crystal lattice, where molecules assumed a freeform configuration instead of the regular, grid-like structure in the rest of the metal, which allowed it to bend.

Researchers claim that this creates many new opportunities for processing and design.

Replacing the volatile and flammable liquid or polymer electrolytes now used in lithium-ion batteries with inorganic solid-state lithium-ionic ceramic conductors could significantly improve both safety and performance of the cells. Solid-state conductors would allow for novel cathode and anode chemistry, prevent the growth of Li-metal dendrites and push miniaturization.Though researchers have inve...

Lithium-ion batteries are notorious for developing internal electrical shorts that can ignite a battery's liquid electrolytes, leading to explosions and fires. Engineers at the University of Illinois have developed a solid polymer-based electrolyte that can self-heal after damage -- and the material can also be recycled without the use of harsh chemicals or high temperatures.The new study could he...

When the volcano, Eyjafjallajökull, erupted in Iceland in 2010, it paralyzed air traffic in large parts of Europe. Volcanoes pose a threat to aircrafts as ash, which commonly contains calcium magnesium aluminum silicates (CMAS), causes significant damage to turbines. Similarly, fly ash, which is a fine powder produced as a byproduct of burning pulverized coal in electric generation power plan...
