<p>[QUOTE=&quot;calcol, post: 2499177, member: 77639&quot;]Actually the melting point of silver goes up with pressure.&nbsp; See: Melting of Copper, Silver, and Gold at High Pressures, Lewis H. Cohen, William Klement, Jr., and George C. Kennedy, Phys. Rev. 145, 519, May 1966.&nbsp; However, solids can flow without becoming liquids, i.e. they do not undergo a phase transition.&nbsp; Press are piece of rubber, and it flows without becoming a liquid.&nbsp; Press metal hard enough, same thing happens.</p><p><br /></p><p>In a liquid, the molecules (atoms in the case of purified metals and many alloys) can move about relatively freely.&nbsp; In a solid flowing under pressure, it is a stepwise process of molecules or atoms being wrenched away from their current neighbors, reforming new strong bonds a short distance away, having these bonds broken to establish new strong bonds in the direction in which the pressure is moving them, etc.</p><p><br /></p><p>Cal[/QUOTE]</p><p><br /></p>
