  • High-powder tungsten-based sintered alloy
    Patent number: 7226492
    Abstract: Tungsten-based alloy material sintered at a high sintering power that may contain additive elements soluble in the nickel and selected from the group constituted, for example, by rhenium, molybdenum, tantalum, niobium, vanadium or a mixture of these, wherein, after sintering in liquid phase at a temperature of around 1500° C., it has: a two-phased ?-? microstructure that is fully densified, has no porosities or has negligible porosities of a low mean grain size (L?) and a contiguity (C??) that is very low with respect to the size of the tungsten crystals, and a dispersion of micro-oxides with no loss of ductility properties.
    Type: Grant
