Commercially pure Cu was processed through high-pressure torsion (HPT) at a pressure of 6 GPa starting from ¼ up to 50 turns. These samples were then naturally aged for 1.75 years under the laboratory condition. Subsequently, ...

Shape memory alloys (SMA) are those class of alloys that can cause shape memory, pseudoelastcity and two-way memory effects due to reversible austenite to martensite phase transformations. The NiTi shape memory alloys ...

Materials for engineering components operating at high temperatures during their service like rockets, aero-turbines, automobile engines, nuclear power plants, steam power plants and micro-electronics are often designed ...

Over a half century, from the advent of chalcogenide glasses, it was used for various applications like xerography, phase change memories (PCM), solar cells, infrared devices and so on. These applications made use of some ...

The selective laser melting (SLM) process is increasingly being adopted for the manufacturing of metal parts as it provides better design flexibility and has the capability to produce near net shape complex parts, which ...

Heat pipes are extensively used in spacecraft thermal control and electronics cooling for transfer of heat from high heat flux zones to low heat flux zones. The major advantage of heat pipe is it can transfer high heat ...

The discovery of coherent g-g’ microstructure in Co-Al-W and Co-Al-Mo-Nb/Ta systems represents new possibilities for turbine engines materials. Their chemical and mechanical properties are similar to commercially successful ...

Tanzania is endowed with rich mineral deposits containing gold, tanzanite, diamond, coal, uranium, iron ore, gemstones with low grade of the sulphide minerals namely chalcopyrite and pyrite. It is the third largest producer ...

A number of researchers have studied about the effects of different nanoparticles on the phase separation of LCST polymer blend systems. Many nanoparticles such as carbon nanotubes and silica have been incorporated in ...

Silicon carbide (SiC) is produced industrially in a heat resistance furnace using quartz (silica) and raw petroleum coke (RPC) as the raw material. In this process, commonly known as the Acheson Process, a large current ...
