microplasticityn.

Brit.

/ˌmʌɪkrə(ʊ)plaˈstɪsᵻti/, U.S.

/ˈˌmaɪkroʊˌplæˈstɪsᵻdi/

Origin: Formed within English, by compounding. Etymons: micro- comb. form, plasticity n.

Etymology: < micro- comb. form + plasticity n.

Materials Science.

Plasticity that occurs at a point below the yield point of a crystalline material; microplastic flow.

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.
