Abstract
Промежуточный металлический состав (лигатура), приспособленный для сплавления с серебром для получения сплава, содержащего по меньшей мере 77 мас.% Ag и по меньшей мере 0,5 мас.% Ge, содержит Cu, Ge и бор вместе с любыми дополнительными компонентами упомянутого сплава и любыми примесями. Предложен также способ получения серебряного сплава, содержащего серебро в количестве по меньшей мере 77 мас.% Ag, 1-7,2 мас.% Cu, по меньшей мере 0,5 мас.% Ge и В вместе с любыми дополнительными компонентами упомянутого сплава и любыми примесями, включающий в себя этап сплавления чистого серебра и промежуточного металлического состава, который является, по меньшей мере, тройным сплавом меди, германия и бора, например 92,5-92,8 мас.% Ag, 6,0-6,3 мас.% Cu, примерно 1,2 мас.% Ge и 1-15 миллионных долей бора в качестве измельчающей зерно добавки. Полученный в результате серебряный сплав проявляет хорошую стойкость к потускнению и к возникновению вызванных пламенем загрязняющих пятен и может проявлять значительное дисперсионное твердение при постепенном воздушном охлаждении. В еще одном аспекте изобретение относится к способу изготовления промежуточного сплава на основе меди для использования при изготовлении продукции из серебряных сплавов, причем расплавленный промежуточный сплав перед затвердеванием обрабатывают разлагаемым соединением бора, например гидридом бора или борогидридом металла.The intermediate metal composition (ligature), adapted for fusing with silver to produce an alloy containing at least 77 wt.% Ag and at least 0.5 wt.% Ge, contains Cu, Ge and boron, along with any additional components of the said alloy and any impurities. A method of producing a silver alloy containing silver in an amount of at least 77 wt.% Ag, 1-7.2 wt.% Cu, at least 0.5 wt.% Ge and B along with any additional components of said alloy and any impurities, which includes the step of fusing pure silver and an intermediate metal composition, which is at least a triple alloy of copper, germanium and boron, for example, 92.5-92.8 wt.% Ag, 6.0-6.3 wt.% Cu, about 1.2 wt.% Ge and 1-15 ppm of boron as a grain refining additive. The resulting silver alloy exhibits good resistance to tarnish and to the occurrence of flame spots caused by the flame and can exhibit significant dispersion hardening with gradual air cooling. In another aspect, the invention relates to a method for manufacturing a copper based intermediate alloy for use in making silver alloy products, wherein the molten intermediate alloy is treated with a decomposable boron compound, such as boron hydride or metal borohydride, before solidification.
