Recently, people devote to the development of beta titanium alloys which have better biocompatibility because of the addition of Mo, Nb, Ta, Zr, Sn, et al. In this paper, the effects of heat treatment and cold roll deformation on the mechanical properties of the Ti-11.3Mo-6.6Zr-4.3Sn alloy (TMZS) are investigated by tensile test. The results show that the excellent combination of strength and d...

In order to improve the high-temperature oxidation resistance of refractory high-entropy alloys (RHEAs), we used micro-arc (MAO) technology prepare ceramic coatings on AlTiCrVZr alloy, and effects voltage microstructure were studied. this paper, MAO was adjusted 360 V, 390 420 450 V. The microstructure, elements distribution, chemical composition, surface roughness studied by scanning electron ...

Phase transformations in a metastable beta Zr–12Nb alloy were investigated by high-energy X-ray diffraction (HEXRD) measured simultaneously with thermal expansion situ during linear heating from room temperature to 800 °C. Complementary in-situ methods of electrical resistance and differential scanning calorimetry, which performed using the same conditions as HEXRD experiment, provided addition...

In this study, beryllium-copper alloy was subjected to around -150° F for cold treatment and to around -300° F for cryogenic treatment and the effects of these cold and cryogenic treatments on the machinability of beryllium-copper workpieces in electro discharge machining have been investigated. Experimental results showed about 20-30 % increase in material removal rate of cold and cryogenic tr...

Exiguobacterium sp. strain JLM-2 is a thermophilic bacterium isolated from deep-sea ferromanganese (FeMn) nodules. The estimated genome of this strain is 2.9 Mb, with a G+C content of 48.32%. It has a novel circular 15,570-bp plasmid. The draft genome sequence may provide useful information about Mn-microbe interactions and the genetic basis for tolerance to environment stresses.

Information systems security defines three properties of information: confidentiality, integrity, and availability. These characteristics remain major concerns throughout the commercial and military industry. In this work, we focus on the integrity aspect of commercial security applications by exploring the nature and scope of the famous integrity policy the Clinical Information Systems Policy....

Ti–6Al–4V alloy is widely used as a system material in high temperature and pressure environments various industrial fields difficult to mechanically machine. Thus, processing methods such hot forging, rolling, forming are usually applied. Among for deriving optimal molding conditions during high-temperature processing, the dynamic model suggests energy dissipation efficiency according flow str...
