The present work attempts to assess the machinability of tungsten heavy alloys (WHAs) with varying tungsten content in terms of different machining characteristics such as chip thickness, material removal rate, cutting force and surface roughness under va... see more

Tungsten heavy alloys are considered as two phase composites with 88 to 97 wt% tungsten interspersed in a matrix of relatively low melting elements such as nickel, iron and cobalt. The mechanical properties of these alloys are greatly influenced by the mi... see more

The article is devoted to the problem of phase composition formation in molybdenum and tungsten electrodeposited alloys as well as to the comparison of data concerning the structure of alloys obtained by means of electrocrystallization and through high-ra... see more

Tungsten is one of the hardest metals that has high melting point and high thermal conductivity. These unique properties make it suitable for many industrial applications. The increasing demand for using tungsten made the need for a fast and reliable anal... see more

The article studies phase composition of etlectrically settled wear-proof coatings of the chromium alloys with tungsten and molybdenum. The basic finding may be applied in machine-building for increasing the service life of units, working under large spec... see more

Effects of sodium nitrite on the corrosion resistance and mechanism of the sputter-deposited W-80Cr-10Zr and W-42Cr-5Ni alloys were studied using corrosion tests and open circuit potential (OCP) measurements in 0.5 M NaCl solution, open to air at 25ºC. Th... see more

There is an urgent need to improve the corrosion resistance of WC-based cermet coatings in different corrosive environments. The main objective of this work was to investigate the microstructure and evaluate the corrosion resistance in neutral, acidic, an... see more

A BALLISTIC PROJECTILE LAUNCHING DEVICE WAS USED TO STUDY THE PENETRATION BEHAVIORS OF TUNGSTEN ALLOY SPHERICAL FRAGMENTS OF VARIOUS DIAMETERS INTO CARBON FIBER COMPOSITE TARGET PLATES OF DIFFERENT THICKNESSES. BASED ON THE BALLISTIC TEST RESULTS, WE OBTA... see more

A smooth particle hydrodynamics (SPH) model was used to simulate the fragmentation process of the jacket during penetrator with lateral efficiency (PELE) penetrating the metal target plate to study the fragmentation characteristics of PELE jacket made of ... see more
