XVI. 155/1 The Microstructure of Bearing Metals. 1956Nature 25 Feb. 380/2 The inhomogeneous microstructure of the muscular tissue. 1959B. Wall tr. Teilhard de Chardin's Phenomenon of Man i. i. 50 We owe our knowledge of the macro-structure and micro-structure of the universe far more to increasingly accurate measurements than to direct observations. 1960E. H. Gombrich Art & Illusion viii. 274 The clue of texture..is basically also a clue of regularity and one which proves so reliable because the micro⁓structure of things is least affected by accidents. 1962F. I. Ordway et al. Basic Astronautics iv. 153 Some hope to learn from gravitational research more about the microstructure of the building blocks of nature, the subatomic particle. 1973Sci. Amer. Feb. 65/2 It is now customary to apply the term ‘microstructure’ to oceanic physical processes on the scale of a few centimeters or less.
Hence microˈstructural a., of or pertaining to the microstructure; microˈstructurally adv.
1893A. Geikie Text-bk. Geol. (ed. 3) 596 Macro-structural metamorphism, having the external structure (morphology) changed, as where an amorphous condition becomes schistose; micro-structural, having the internal structure (histology) wholly changed, with or without a macro-structural alteration. 1937O. B. Darbishire tr. A. von Buzágh's Colloid Syst. iv. 45 With increasing crystal size the microstructural composition asymptotically approaches the stoichiometric composition. Ibid., The solution of this paradox is found in a ‘microstructurally correct computation’. 1966C. R. Tottle Sci. Engin. Materials x. 224 Steels are susceptible to microstructural changes at the temperatures required for stress relief, and for this reason relief is often avoided. |
