WebSep 6, 2001 · aging for something like 90 days. Note that 100 ppm translates to 2,000 Hz for a 20 MHz oscillator or crystal. Temperature effects The frequency vs. temperature curve is a strong function of how the crystal was cut. For narrow temperature range applications the turning point can be controlled so that the slope WebSep 26, 2024 · The crystal structure of the β’’ (Mg 5 Si 6) phase has been identified as a C-centered monoclinic structure by using HRTEM observations, ab initio calculations, and atom probe tomography ... The existence of two different phases explains the shape of the aging curve: between 3 h and 8 h of aging the pre-β′′ transforms into β′′. ...
