31. Hardness, toughness, dielectric constant and many other properties are microstructure -dependent. 32. This allows the macro-and microstructure of a mechanical component in one step. 33. The test wall is calcareous, perforate, bilamellar, with a radial microstructure . 34. Inconel 625 was designed as a solid solution strengthened material with no significant microstructure . 35. The root cause of many ceramic failures is evident in the cleaved and polished microstructure . 36. The sample can then be etched to reveal the microstructure and macrostructure of the metal. 37. Metallic materials consist of a microstructure of small crystals called " grains " or crystallites. 38. This forms a layered microstructure called pearlite. 39. The post-formed microstructure revealed that there was no significant change in grain size. 40. Davenport and Bain originally described the microstructure as being similar in appearance to tempered martensite.
