1936 B. Chalmers in Proc. Royal Soc. A. 156 427 The existence has been established of a type of plasticity below the point usually regarded as the yield point, and it is suggested that this phenomenon be designated as ‘micro-plasticity’.
1966 Jrnl. Strain Anal. 1 415/2 It is believed that micro-plasticity constitutes an important source of failure in the case of metal fatigue.
1972 T. Imura in G. Thomas Electron Microsc. & Struct. Materials 129 The microplasticity can be attributed solely to the motion of edge dislocations.
1994 Jrnl. Alloys & Compounds 211 83 The correlation between micro- and macroplasticity is discussed.
