Nd 12.5 Fe 82 B 5.5 ribbons have been prepared by a melt spinning technique at a wheel speed ranging from 5 to 22 m/s. It was found that the wheel speed v R dramatically influences the microstructure and magnetic properties of the ribbons. At an optimized v R , a structure with single-phase Nd 2 Fe

In this Paper the mechanical relaxation of polymers at low temperatures is investigated. The shear modulus, mechanical loss tangent, and damping behaviour of various amorphous and semicrystalline polymers are reported.
Organic insulators, such as polyimide, epoxy resins and fibre reinforced epoxies, are irradiated in the fission reactor at about 5 K and the mechanical properties are measured in liquid helium and in liquid nitrogen without warm up. At very low temperatures, the materials are completely brittle. Af
