Probing metal solidification nondestructively

Researches and collaborators at Los Alamos Laboratory (Los Alamos, N.M.) used nondestructive imaging techniques to study the solidification of metal alloy samples. The team used complementary methods of proton radiography at the Los Alamos Neutron Science Center (LANSCE) and synchrotron x-ray radiography at Argonne National Laboratory (ANL) to make the measurements. This is the first time that high-energy protons have been used to nondestructively image a large metal sample during melting and solidification.

3D metal printing

3D printing of stainless steel parts This video from How It’s Made shows the process of building stainless steel parts by 3D printing. Three-dimensional metal printers can build parts faster and cheaper than conventional casting or machining. They build objects from successive layers of stainless steel powders that are then fused together at high temperatures.  […]

Thickness gage measures inside corroded pipes

Olympus Corp., Waltham, Mass., a world leader in nondestructive testing technologies, is pleased to announce the release of the 27MG Ultrasonic Thickness Gage is designed to make accurate measurements from one side on internally corroded or eroded metal pipes and structures.

Exotic material is like a switch when super thin

Ever-shrinking electronic devices could get down to atomic dimensions with the help of transition metal oxides, a class of materials that seems to have it all: superconductivity, magnetoresistance and other exotic properties.
