²éÁËһϣº Decohesive Rupture (Brittle Intergranular Fracture or Grain Boundary Separation) is associated almost exclusively with rupture along grain boundaries and arises at marked differences between the properties of grain boundaries and matrix (grain boundary embrittlement by thermally activated segregation, impurities at the grain boundaries, formation of precipitates or a continuous film along the boundaries). The morphology of intergranular fracture facets depends on the cause of the failure; the facets can be smooth or rough. µ«µÄÈ·²»ÖªµÀÔõôȷÇеķÒë Ó¦¸ÃÊdz£ËµµÄÑØ¾§¶ÏÁÑ [ Last edited by xucz on 2009-6-23 at 08:52 ] |
