CUSTOMER SPOTLIGHT
CUSTOMER SPOTLIGHT... This month, we're featuring Becky Merritt, who used a piece of aluminum from Speedy to make a solar oven:
She painted the aluminum black, and used it as the bottom of the oven, which was able to reach 200℉! Then she made some delicious-looking Chocolatey Krispy Treats:

DID YOU KNOW?
DID YOU KNOW...? ...that researchers have discovered a new mechanism for bending metal?
Normally, increasing a metal's strength (for example through cold working or annealing) reduces its ductility, making it more prone to fracturing when bending. This is because a metal's ability to bend depends on irregularities in the crystalline structure, and increasing a metal's strength reduces the ability of these irregularities to move, thus reducing flexibility. Now, however, Izabela Szlufarska, a professor of materials science and engineering at UW–Madison, has made an important discovery: "[B]ending samarium cobalt caused narrow bands to form inside the crystal lattice, where molecules assumed a free-form “amorphous” configuration instead of the regular, grid-like structure in the rest of the metal.
Those amorphous bands allowed the metal to bend.
'It’s almost like lubrication,' says Szlufarska. 'We predicted this in simulations, and we also saw the amorphous shear bands in our deformation studies and transmission electron microscopy experiments.'"
