Abstract

"PRODUTOS DE MOINHO DE METALURGIA DE PULVERIZADO DE METAL REFRATáRIO DE TAMANHO DE GRãO ESTABILIZADO". A presente invenção refere-se a produtos de moinho de metal em pó (P/M) e método para fabricação de tal produto feito com metal refratário com baixo teor de oxigênio (< 400 ppm), ou ligas do mesmo, usando aditivos de óxido (tais como MgO, SiO~ 2~ e Y~ 2~O~ 3~) para co-fabricação para alcançar a estabilização do tamanho de grão de metal refratário como requerido em aplicações a altas temperaturas. Um desses produtos é uma folha com tamanho de ação pequeno contendo partículas de óxido como estabilizadores de tamanho de grão. O produto possui boas propriedades mecânicas, baixo teor de oxigênio em derivados de fibra de metal refratário do pó dentro do produto de moinho e, se disponível, como grandes pedaços de folha (dimensões laterais). O pó de metal é consolidado a uma barra falha por diferentes métodos, que pode pesar 22,6 kg (50 libras) ou mais."STABILIZED GRAIN SIZE REFRACTORY METALURGY SPRAY METALURGY PRODUCTS". The present invention relates to powdered metal (P / M) mill products and method for manufacturing such a product made from low oxygen refractory metal (<400 ppm) or alloys thereof using oxide additives. (such as MgO, SiO ~ 2 ~ and Y ~ 2 ~ O ~ 3 ~) for co-fabrication to achieve refractory metal grain size stabilization as required in high temperature applications. One such product is a small size sheet containing oxide particles as grain size stabilizers. The product has good mechanical properties, low oxygen in powder refractory metal fiber derivatives within the mill product and, if available, as large pieces of sheet (side dimensions). Metal powder is consolidated to a failing bar by different methods, which may weigh 22.6 kg (50 pounds) or more.
