Abstract
In addition to the oxidizability and poor weldability of refractory metals, their cold brittleness forms the principal obstacle to their utilization in the new technology. Transition from the ductile to the brittle state occurs in refractory metals in a certain temperature range. Group Va metals and particularly group VIa metals having a bcc lattice show a tendency to lose ductility on cooling (Fig. 73). Group VIa metals and primarily tungsten have the highest ductile—brittle transition temperature. Iron is the classic example of a cold-brittle metal.
