Mechanical alloying (MA) is an established way to prepare nanocrystalline materials and metastable solutions of materials, which normally have no mutual solubility.
An important class of materials produced by mechanical alloying, also called milling, are nanostructured materials and especially oxide dispersion strengthened (ODS) steels [1].
Atom probe investigations were performed on the as-milled powder particles and on as-HIPed materials.

Introduction Unlike traditional lasers which a Fabry-Perot cavity and an optical gain material are indispensable for the system to lase, RL is a special kind of lasers in which the cavity is formed with closed-loop random cavities owing to multiple scattering of photons in the amplifying media and determines the resonant frequency and threshold of the lasers.

Introduction Concrete is one of the main materials of buildings such as the traffic, civil, hydraulic, etc.
Because of the complexity of the mechanical properties of constituent materials and the presence of internal cracks, the research on the deformation and the process of failure is very complex.
