Abstract
Metal and ceramic members are joined together by a braze joint including a member made of bar stock molybdenum, a first ductile member brazed between the molybdenum member and the metal member, and a second ductile member brazed between the molybdenum member and the ceramic member. The braze joint may be used to join a ceramic wheel shaft to a metal shaft in a turbomachine. The braze joint allows torsion to be transmitted between the ceramic wheel shaft and the metal shaft without the use of a metal sleeve.
