;
A definitive investigation of the boron-carbon equilibrium system is being made by x-ray-diffraction, metallographic, and thermal analytical techniques. Alloys are being produced by sintering pressed powder aggregates with subsequent arc melting. Alloys were made at two at.% intervals up to 30 at.% carbcn. In the future, higher carbon compositions are to be investigated. Techniques were worked out for the metallographic preparation of the extremely hard and friable alloys. (auth)
