<p>[QUOTE=&quot;bdunnse, post: 2108951, member: 57317&quot;]<i>Most </i>metals will remain in its solid state if you increase pressure and hold the temperature constant. It may yield and undergo plastic deformation but it won&#039;t melt. Water will phase shift from solid (ice) to liquid (water) with a pressure increase alone, but water is just weird that way.</p><p>&nbsp;</p><p>Increasing temperature alone will make metals go from solid to liquid if you increase it enough ( <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie100" alt=":wideyed:" unselectable="on" unselectable="on" /> ). If you increase pressure too, then you will <i>generally</i> need to increase temperature even more so to get it to melt.</p><p>&nbsp;</p><p>Increasing pressure rapidly (like when a coin is minted or when a train runs over a coin or when Kentucky boy goes medieval on an innocent piece of wire with a hammer <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie2" alt=";)" unselectable="on" unselectable="on" /> ) will result in some increase in temperature (conversion of some of the kinetic energy into heat), but not enough to melt metal. Another thing, the pressure increase comes and goes long before the temperature increase can penetrate to any significant depth.[/QUOTE]</p><p><br /></p>
