There is disclosed a laser comprising a laser medium comprising H 2 (1/p) where p is an integer and 1≦p≦, a cavity comprising the laser medium, and a power source to form an inverted population in the energy level of H 2 (1/p). The power source may form excited vibration-rotational levels of H 2 (1/p) wherein lasing occurs with a stimulated transition from at least one vibration Cited by: 7.

[Animesh Bose; Robert J Dowding; Metal Powder Industries Federation.; Refractory Metals Association.;] -- The papers presented in this meeting examined the rapid advancement in the technology of refractory metals, with special emphasis on the.
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. This includes the following metals and their refractory alloys: Tungsten, Molybdenum, Chromium, Tantalum, Niobium and Rhenium”. Material selection process for incandescent lamps Cited by: 4.

1. Introduction. Tungsten heavy alloys with superior mechanical properties have attracted considerable attention for kinetic energy penetrator applications.Conventional tungsten alloys in sintered plus heat treated condition exhibit tensile strength and elongation in the range of – MPa and 20–30%.However, for penetrator application, superior mechanical properties especially Cited by: International Journal of Refractory Metals and Hard Materials.

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.

low, making it difficult to spray ceramics and refractory metals. The main features of this process are high density, good adhesion, and no formation of oxides, mainly because of the high-impact. 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.
