The invention relates to a plasma spray method which can serve as a starting point for a manufacture of metal nanopowder, nitride nanopowder or carbide nanopowder or metal films, nitride films or carbide films. To achieve an inexpensive manufacture of the nanopowder or of the film, in the plasma spray in accordance with the invention a starting material (P) which contains a metal or silicon oxide is introduced into a plasma jet ( 113 ) at a process pressure of at most 1000 Pa, in particular at most 400 Pa. The starting material (P) contains a metal or silicon oxide which vaporizes in the plasma jet ( 113 ) and is reduced in so doing. After the reduction, the metal or silicon which formed the metal or silicon oxide in the starting material is thus present in pure form or in almost pure form. The metal or silicon can be deposited in the form of nanopowder or of a film ( 124 ). Nitride nanoparticles or films or carbide nanoparticles or films can be generated inexpensively by addition of a reactant (R) containing nitrogen or carbon.

Composites of bulk amorphous alloy and fiber/wires

Номер: US20140007986A1
Автор: Christopher D. Prest, Dermot J. Stratton, Joseph C. Poole, Matthew S. Scott
Принадлежит: Apple Inc

A composite structure includes a matrix material having an intrinsic strain-to-failure rating in tension and a reinforcing material embedded in the bulk material. The reinforcing material is pre-stressed by a tensile force acting along one direction. The embedded reinforcing material interacts with the matrix material to place the composite structure into a compressive state. The compressive state provides an increased strain-to-failure rating in tension of the composite structure along a direction that is greater than the intrinsic strain-to-failure rating in tension of the matrix material along that direction. At least one of the matrix material and the reinforcing material is a bulk amorphous alloy (BAA). The reinforcing material can be a fiber or wire. In various embodiments, the matrix material may be a bulk amorphous alloy and/or the reinforcing material may be a bulk amorphous alloy.

ADDITIVE MANUFACTURING POWDERS WITH IMPROVED PHYSICAL CHARACTERISTICS, METHOD OF MANUFACTURE AND USE THEREOF

Номер: US20220288676A1
Автор: Cauchy Xavier, Rahma Hakim
Принадлежит:

In additive manufacturing operations, powders used in stereolithographic processes need to be precisely spread out in a uniform fashion at every pass of the stereolithographic process to ensure predictability in powder surface morphology. Typically, this is difficult to achieve with conventional powders because often these powders suffer from poor flowability, which may further deteriorate over time, and impairs the efficiency of the stereolithographic processes. The present disclosure describes additive manufacturing powders having improved physical characteristics such as flowability and tap density, which are less sensitive or insensitive to ambient humidity. For example, there is described a powder that includes spherical particles having a particle size distribution of less than 1000 micrometers and having a measurable flowability as determined in accordance with ASTM B213 at 75% relative humidity. 1.

FIELD: metallurgy. SUBSTANCE: invention relates to production of ingots from zirconium alloys based on zirconium magnesium-thermal sponge containing alloying elements. Method involves obtaining ligatures tablets, forming consumable electrodes and casting ingots. Ligature tablets are obtained by mixing and pressing alloying components in pure form, or in form of their compounds, or with addition of electrolytic zirconium powder or zirconium magnesium-thermal sponge. Method comprises pressing briquettes from a mixture containing zirconium-containing materials in the form of zirconium magnesium-thermal sponge, ground zirconium iodide and/or zirconium production, and obtained ligature tablets are uniformly distributed in charge by mechanical mixing. Formation of consumable electrodes is carried out by welding briquettes between each other. EFFECT: high chemical homogeneity of ingots from zirconium alloys based on magnesium-thermal sponge. 5 cl, 2 tbl РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 700 892 C2 (51) МПК C22B 9/20 (2006.01) C22C 16/00 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК C22B 9/20 (2018.08); C22C 16/00 (2018.08); B22F 3/02 (2018.08) (21)(22) Заявка: 2018105420, 13.02.2018 (24) Дата начала отсчета срока действия патента: Дата регистрации: 23.09.2019 (43) Дата публикации заявки: 13.08.2019 Бюл. № 23 (45) Опубликовано: 23.09.2019 Бюл. № 27 2 7 0 0 8 9 2 R U (56) Список документов, цитированных в отчете о поиске: JP 61030637 A, 12.02.1986.
