Abstract

Abstract Translated from German Heterogenes Wolframlegierungspulver zur Herstellung von Sinterteilen mit porenfreiem Gefüge, insbesondere von Wuchtgesch ossen. Das Pulver enthält neben Wolfram eine Binderphase aus Nickel, Kobalt und Eisen und besteht aus 10 - 50 µm grossen Partikeln, wobei die Partikel eine schwammartige Struktur besitzen, die gebildet wird von Wolframkörnern < 1 µm, die ihrerseits umhüllt und zusammengehalten wird von einer dünnen Schicht einer homogenen Ni-Co-Fe-Binderphase (Matrix). Weiterhin werden Herstellungsverfahren angegeben. Heterogeneous tungsten alloy powder for the production of sintered parts with a non-porous structure, in particular balancing projectiles. In addition to tungsten, the powder contains a binder phase made of nickel, cobalt and iron and consists of 10 - 50 µm particles, the particles having a sponge-like structure that is formed by tungsten grains <1 µm, which in turn is enveloped and held together by a thin layer a homogeneous Ni-Co-Fe binder phase (matrix). Manufacturing processes are also specified.
