摘要： A method of direct casting crystalline metal sheet in continuous strip form from a melt of metal having a melting point below about 900.degree. C. on a continuously driven substantially smooth chill surface cooled to extract heat from the strip being cast avoids gas pockets between the strip and chill surface by applying heat from an external source to the chill surface prior to the chill reentering the melt whereby vaporizable condensates and deposits on the chill surface are eliminated prior to contact with the melt.

摘要： A melt drag metal strip casting system of the type wherein molten metal is delivered from a supply of the molten metal into contact with a grooved chill surface at a casting station and the chill surface is driven for movement in a path past the casting station at a predetermined linear rate to quench and withdraw a continuous strip of metal from the molten metal supply, the grooves in the chill surface being gradually parallel and spaced from one another to provide land regions between adjacent grooves and the strip having a bottom surface adhering to the land regions of the chill surface and an unsolidified top surface as it is withdrawn from the molten metal supply, including a top roll adjustable mounted above the chill surface and spaced therefrom by a distance substantially equal to the thickness of the strip desired with the top roll in contact only with the unsolidified top surface of the strip, with the temperature of the top roll surface in contact with the unsolidified top surface of the strip being maintained at a level which will not solidify the top surface of the metal being cast.

摘要： Ceramic tantalum carbide artifacts having high thermal shock and mechanical erosion resistance are provided by incorporating tungsten-rhenium and carbon particles in a tantalum carbide matrix. The mix is sintered by hot pressing to form the ceramic article which has a high fracture strength relative to its elastic modulus and thus has an improved thermal shock and mechanical erosion resistance. The tantalum carbide is preferable less than minus 100 mesh, the carbon particles are preferable less than minus 100 mesh, and the tungsten-rhenium particles are preferable elongate, having a length to thickness ratio of at least 2/1. Tungsten-rhenium wire pieces are suitable as well as graphite particles.
