“Refractory Metal, RM – Wrap”: A tailorable, pressure-less joining technology
Original language description
The RM-wrap (RM = Refractory Metal) is a pressure-less, versatile and tailorable joining process: it consists of wrapping Si foils inside a refractory metal wrap (i.e., Mo, Nb, Ta) in order to prevent molten silicon from leaking outside the joined region and infiltrating the facing materials during the joining process.nRM-wrap (RM = Mo, Nb, Ta) has been successfully applied to join C/SiC composites in this work: optimized joining treatment consisted of heating to 1450 °C with a heating rate of 1000 °C/h followed by a dwell time of 5 min in a non-reactive environment of Argon flow.nThe joints were characterized by morphological analysis and lap shear tests at room temperature and 1000 °C.nMicroscopical analysis revealed an in-situ formed composite joint consisting of a silicon matrix reinforced with silicides of the refractory metals. Joining material exhibited continuous and cracked free bonding with C/SiC irrespective of composite fibre orientation.nJoints lap shear strength values at 1000 °C were higher than at room temperature, probably due to the brittle to ductile transition (BTDT) of silicon and silicides.nVickers microhardness on refractory metal disilicides measured inside the joints showed a trend similar to their mechanical strength, with higher lap shear strength and hardness for Mo-Wrap and lower for Ta-wrap joints.n
