Metallurgists have all kinds of ways to make a chunk of metal harder. They can bend it, twist it, run it between two rollers or pound it with a hammer. These methods work by breaking up the metal's grain structure—the microscopic ...

(PhysOrg.com) -- One of the issues afflicting magnetic memory is the fact that it is difficult to store information for as long as 10 years. In order to overcome this problem, scientists and engineers have been looking for ...
How will materials behave under certain conditions? And how to make materials more robust? These two questions are crucial to design advanced materials for structural and functional components and applications. A close look ...
