Preliminary Results for HIP Bonding Ta to W Targets for the Materials Test Station

摘要

Tungsten targets for the Materials Test Station (MTS) were clad with thin tantalum cover plates and a tantalum frame using hot isostatic pressing (HIP). A preliminary HIP parameter study showed good bonding and intimate mechanical contact for Ta cover plate thicknesses of 0.25 mm (0.010inch) and 0.38 mm (0.015 inch). HIP temperatures of full HIP runs were 1500°C (2732°F). HIP pressure was 203 MPa (30 ksi).
