Grain-boundary displacement vs grain deformation as the rate-determining factor in creep

Abstract

The height of the vertical grain-boundary displacements was measured on creep specimens of β-brass. The displacements followed a normal distribution whose standard deviation was a function of strain and was independent of temperature from 450° to 501°C. The strength of the grain, not the shear resistance of the boundary, was found to be the rate-controlling factor in the creep of β-brass.
