Viscous Creep in Metallic Wires at Elevated Temperatures and Low Stresses.
Original language description
Viscous creep behaviour of several metals and alloys was investigated at the temperatures close to one half of the absolute melting point and very low stresses using the technique of helicoid specimens. Due to extremely high sensitivity the technique provides a unique tool for measurement of very low creep strains in acceptable time of the experiment. Helicoid spring specimens were made of wires of either circular or square cross section. The stress distribution along the wire radius (caused by shear stress loading) and threshold stresses were taken into account, as well as the influence of the surface layer loaded by maximum stress. The experimental results were interpreted as Coble diffusional creep and/or Harper-Dorn dislocation creep. Some data arein a very good agreement with Coble theory especially those obtained on some fine grained materials. This dependence is replaced by large data scatering for coarse grained materials. Some authors dispute the role or even the very existen
