Comment on “Aging-induced anisotropy of mechanical properties in steel products: Implications for the measurement of engineering properties” by Richards et al. [Mater. Sci. Eng. A 529 (2011) 184]

The concept of a “Strain aging induced anisotropy in mechanical properties”, proposed by Richards et al. [Mater. Sci. Eng. A 529 (2011) 184], is shown to be misleading. Anisotropy of strain aging kinetics is proposed as a possible source of confusion.
