Powder dispersions of titanium--boron and titanium-boron carbide were prepared, clad, and evaluated for use as control materials. Compacts possessing up to 95 per cent of theoretical density were prepared by a hot-pressing technique. The relatively low temperatare of 1500 deg F was used to obtain the desired high density. There was no visible reaction between the boron dispersant and titanium. Excellent metallurgical cladding of the titanium-- boron dispersion with titanium was achieved by the use of both rollbonding and gas pressure-bending techniques. The rolling was performed at 1500 deg F and the pressure bonding was accomplished at 1600 deg F …

Description
Powder dispersions of titanium--boron and titanium-boron carbide were prepared, clad, and evaluated for use as control materials. Compacts possessing up to 95 per cent of theoretical density were prepared by a hot-pressing technique. The relatively low temperatare of 1500 deg F was used to obtain the desired high density. There was no visible reaction between the boron dispersant and titanium. Excellent metallurgical cladding of the titanium-- boron dispersion with titanium was achieved by the use of both rollbonding and gas pressure-bending techniques. The rolling was performed at 1500 deg F and the pressure bonding was accomplished at 1600 deg F with a helium pressure of 10,000 psi for a time of 6 hr. The pressure-bonding technique produced a specimen with a more uniform boron dispersion and a better high-temperatare-water corrosion resistance than were obtained through roll bonding. Extruded titanium--boron dispersions were joined to hafnium and clad with Zircaloy-2 by a roll-bonding technique to determine in a preliminary way the feasibility of preparing clad composite control rods. Strong, relatively ductile bonds were obtained between all of the components by the rollbonding process and postfabrication heat treatment. (auth)
