<p>[QUOTE="bdunnse, post: 2499161, member: 57317"]Perhaps the pressure is high enough to lower the melting point of the metal, but because the pressure is only that high for a short duration is there actually enough time for the material to undergo the phase transformations? A pure guess is that the peak pressure is sustained for just a few milliseconds. I don't know the answer but I am just voicing my internal bullshit detector's voice. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie8" alt=":D" unselectable="on" unselectable="on" /></p><p><br /></p><p>BTW, liquefaction is a loss of shear strength due to shaking, not necessarily a large increase in pressure.[/QUOTE]</p><p><br /></p>
