“…It consists of a ductile phase (a-Ti, which is the matrix) and a brittle phase (Ti 5 Si 3 , acts as the reinforcement). The Ti 5 Si 3 compound has a complex D8 8 hexagonal structure (Mn 5 Si 3 -type, a = 0.7444 nm, c = 0.5143 nm) and has a high melting point (2130°C), low density (4.32 g/cm 3 ), good oxidation resistance, and creep resistance [1,2]. This composition is similar to the extensively-applied Fe-C and Al-Si eutectic alloys.…”

The effect of Al element alloying on the microstructure and tribological behavior of Ti-Si eutectic alloys has been studied. The experimental results show that Al element changes the microstructure from large eutectic cells that consist of layered tablet phases Ti 5 Si 3 and a-Ti (for the Al-free alloy) to near-equiaxed or rod-like Ti 5 Si 3 particle reinforced continuous a-Ti (Al, Si) solid solutions. This microstructural change greatly improves the ductility and reduces brittle fracture of massive superficial materials during wear process. Microplough and local delamination are the main wear mechanisms of Al-added Ti-Si alloys. Therefore, the wear resistance and friction stability are simultaneously improved.

“…Here we present an example of a movie of a self-propagating high temperature reaction [38][39][40][41][42][43][44][45] in a stoichiometric mixture of titanium and silicon. In these reactions the material changes from a pressed powder to a ceramic pellet.…”

An application of nuclear physics, a facility for using protons for flash radiography, has been developed at the Los Alamos Neutron Science Center (LANSCE). Protons have proven far superior to high energy x-rays for flash radiography because of their long mean free path, good position resolution, and low scatter background. Although this facility is primarily used for studying very fast phenomena such as high explosive driven experiments, it is finding increasing application to other fields, such as tomography of static objects, phase changes in materials and the dynamics of chemical reactions. The advantages of protons are discussed, data from some recent experiments will be reviewed and concepts for new techniques are introduced.

“…Subsequently, niobium silicides were yielded by the precipitation from saturated liquid solution. This dissolution-precipitation reaction mechanism is typically adopted in the combustion synthesis of many metal silicides, such as the Ti-Si [17,18] and Zr-Si [19] intermetallic compounds. The activation energy of a self-sustained reaction is generally determined by means of realizing the dependence of reaction front velocity on combustion temperature.…”
