摘要
We present examples of detection of high-pressure phase transitions in three different materials using acoustic emission monitoring in a multi-anvil cell. The technique is sensitive to spontaneous strains as small as similar to 10(-12) m(3). We suggest that monitoring acoustic emissions might prove useful in studying the kinetics of phase transformation and in performing pressure calibrations in systems where no electrical signal, or other in situ probe method, is readily available.
