postuniform

English

Etymology

From post- +‎ uniform.

Adjective

postuniform (not comparable)

1. (metallurgy) Pertaining to the state where elongation is a function of the strainrate hardening exponent determined near maximum load

     This produces a more uniform strain distribution. This is of special significance in the postuniform elongation region, where necking and high strain concentrations occur. An approximately linear relationship has been found between the m value and postuniform elongation for various steels and nonferrous alloys [17].

   • 2014, Comprehensive Materials Processing, page 370:

     Deformation continues during postuniform strain in the neck and initiates microvoid formation around hard particles such as inclusions and carbides, leading eventually to ductile fracture surfaces characterized by coalesced microvoids.

     However, excess boron is desirable for improving postuniform elongation because it suppresses carbide precipitation at the grain boundary.
