A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Abstract. A large number of tungsten alloys and composites were investigated in the past, but only some of them achieved technical importance.

However, these are of significant commercial interest and will be discussed in the following sections. Robert J. Dowding Quasistatic and dynamic compression tests were conducted on four tungsten preform reinforced Vit (ZrTi5CuNiAl10) and Vit (Zr57Nb5CuNiAl10) metallic.

“The refractory metals comprise selected metals with melting points around °C and higher, with similar powder metallurgical production and application.

The effect of the size and shape of tungsten particles on dynamic torsional properties in tungsten heavy alloys was investigated. Dynamic torsional tests were conducted on seven tungsten alloy specimens, four of which were fabricated by repeated sintering, using a torsional Kolsky bar, and then the test results were compared via microstructure, mechanical properties, adiabatic shear Cited by: 9.

In this study, tungsten heavy alloy specimens were fabricated by mechanical alloying (MA), and their dynamic torsional properties and penetration performance were investigated.

Dynamic torsional tests were conducted on the specimens fabricated with different sintering temperatures after MA, and then the test data were compared with those of a conventionally processed by: X Tungsten and Refractory Metals 3, - Proceedings of the Third International Conference on Tungsten and Refractory Metals Critter Pals, School Specialty Publishing.

The effects of refractory (R) elements (R = Re, Ru, W, or Ta) on a base Ni-Al-Cr alloy are studied, for an aging temperature of K ( °C) and an aging time of h, employing atom-probe.
