Powder metallurgy production of high performance alloys

Abstract: 1. THE PROCESS OF MAKING A COHERENT GREEN COMPACT WHICH HODS ITS SHAPED DURING SINTERING FROM PRE-ALLOYED COMMINUTED POWDER OF A HIGH PERFORMANCE METAL ALLOY WHICH CANNOT BE PRESSURE COMPACTED UNDER PRESSURES UP TO 70 TONS PER SQUARE INCH UNLESS ITS AVERAGE PARTICLE SIZE IS NOT GREATER THAN ABOUT 5 MICRONS, COMPRISING PROCESSING THE ALLOY POWDER TO AN AVERAGE PARTICLE SIZE BETWEEN ABOUT 9 AND ABOUT 30 MICRONS, MIXING THE ALLOY POWDER WITH A DRY, FINELY DIVIDED ORGANIC BINDER IN AMOUNTS NOT GREATER THAN ABOUT 5% BY WEIGHT OF THE ALLOY POWDER SO AS TO OBTAIN A UNIFORM DISPERSION OF BINDER IN THE ALLOY POWDER, THEN ADDING A SOLVENT FOR THE BINDER IN AMOUNT SUFFICIENT TO FORM A PLASTIC MIXTURE WITH THE ALLOY POWDER AND BINDER, THEN CONSOLIDATING THE PLASTIC MIXTURE TO A BULK DENSITY INTERMEDIATE THAT OF THE POWDER AND THAT OF THE CAST ALLOY, THEN DRYING THE CONSOLIDATED MIXTURE TO EVAPORATE THE SOLVENT, THEN CRUSHING THE CONSOLIDATED MIXTURE TO DISCRETE AGGLOMERATES OF PRE-ALLOYED POWDER PARTICLES TO PROVIDES A SUBSTANTIAL FRACTION OF -100 MESH PARTICLES AT LEAST ABOUT HALF OF THE -100 MESH FRACTION OF WHICH ARE-325 MESH, THEN FILLING A DIE OF THE DESIRED SHAPED WITH THOSE AGGLOMERATES, THEN COMPACTING THE AGGLOMERATES IN THE DIE UNDER PRESSURE TO AT LEAST ABOUT 50% OF THE CAST DENSITY OF THE ALLOY SO AS TO PRODUCE A COHERENT GREEN COMPACT, AND THEN REMOVING THE COMPACT FROM THE DIE.

Surface modified silica

Abstract: A novel and improved surfactant modified silica and method for making the same. The surfactant modified silica is characterized as a fumed silica having a surfactant material treated therewith. Also disclosed is process of thickening aqueous systems which includes the addition of an effective amount of a fumed silica having a surfactant material treated therewith.

Introducing a grain refining or alloying agent into molten metals and alloys

Abstract: A molten metal or alloy is inoculated with metallic treating agent by pouring the molten metal into a troughlike passageway and by introducing a rodlike supply of the metallic treating agent into the molten metal flowing in the passageway under conditions insuring a disturbed but nonturbulent flow of the molten metal and resulting uniform distribution of the treating agent therein.

Methods for the deposition of conductive electronic features

Abstract: A precursor composition for the deposition and formation of an electrical feature such as a conductive feature. The precursor composition advantageously has a low viscosity enabling deposition using direct-write tools. The precursor composition also has a low conversion temperature, enabling the deposition and conversion to an electrical feature on low temperature substrates. A particularly preferred precursor composition includes copper metal for the formation of highly conductive copper features.
