Abstract

Stopowy proszek do wytwarzania stopów wolframu metodą metalurgii proszków, składa się z proszków wolframu, stopowego proszku TiH2 w ilości do 0,3% wagowych i proszku elementarnego Y w ilości do 0,3% wagowych. Użycie, proszków TiH2 i Y, jako dodatków stopowych do stopu wolframu, powoduje, że w procesie mechanicznego stopowania reagują one z takimi zanieczyszczeniami stopu jak węgiel i tlen, powodują tworzenie lotnych związków, które następnie mogą być usunięte z komory roboczej młyna. Zabieg ten pozwala na zredukowanie szkodliwych pierwiastków, takich jak tlen i węgiel do 25%.Alloyed powder for the production of tungsten alloys by powder metallurgy, consists of tungsten powders, TiH2 alloy powder up to 0.3% by weight and elemental powder Y up to 0.3% by weight. The use of TiH2 and Y powders as alloying additives for a tungsten alloy causes that in the mechanical alloying process they react with alloying impurities such as carbon and oxygen, creating volatile compounds that can then be removed from the mill's working chamber. This treatment allows you to reduce harmful elements such as oxygen and carbon by up to 25%.
