Grain Size - an overview ScienceDirect Topics

Grain size has an effect on the fracture toughness of ferroelectric ceramics. Optical microscopic observation of Vicker's indents on PLZT 9/65/35 ceramics with different grain sizes indicates that the crack size becomes shorter as the grain size decreases, while the pyramid diagonal remains the same with respect to the grain size changing (Uchino, 1997).

Grain Size Measurement Methods: A Review and

Grain size measurements began in 1894 with the publication by Albert Sauveur who reported the grain size in terms of the number of grains per unit area. But, Sauveur did not describe his test method. Later, his graduate student, Zay Jeffries, described the approach in detail. Jeffries was a founding member of ASTM Committee E-4 on Metallography ...

Grain Size and Its Influence on Materials Properties

2011-5-16  Grain size has a measurable effect on most mechanical properties. For exam-ple, at room temperature, hardness, yield strength, tensile strength, fatigue strength and impact strength all increase with decreasing grain size. Machinability is also affected; rough machining favors coarse grain size while finish machining favors fine grain size.
