Abstract: To provide an alloy having high strength, toughness, and which is highly resistant to impact loading, the alloy has the following composition (all percentages by weight): 2-4.5 Mo, more than 2.5 to less than 3.5% Ni, more than 0.3 to less than 0.6% P, the rest iron; preferably, 3% Mo, 3% Ni, 0.45% P and the rest iron are used.
Abstract: Columbium powder capable of producing anodes of improved electrical capacitance is prepared by the addition of phosphorus-containing materials in amounts from about 5 to about 600 ppm based on elemental phosphorus.
Abstract: Electrical contact material of silver or mixtures of silver and a thermally decomposable compound of silver having an additive of an alkali metal, for example lithium, added in the form of a salt prior to sintering to increase the as-sintered density of the resulting material and to aid in the prevention of undesirable surface blisters. The silver material may be fabricated as a backing layer on a primary contact material of silver-cadmium oxide.
Abstract: The present invention relates to improved heat insulating particles with a high heat insulating effect and high mechanical strength. The particles are smooth cells formed around hollow or solid grains of a low heat-conducting material such as silica, alumina, glass, or a synthetic resin like nylon or teflon, which are coated with a material that can readily reflect the heat radiation such as aluminum, copper, gold, silver, stainless steel or titanium. The cells thus-formed are bound together by sintering in the form of a block or any other desirable shape so that the metallic surface cells are bonded together at their points of contact through molecular dispersion of the metal molecules of the respective surfaces.
