  • struktuur, mida iseloomustab uue faasi formeerumine lähtetardlahuses piki kindlaid kristallograafilisi tasandeid (vt tardlahus, faas)
    Good to know
    • Alaeutektoiteraste puhul ilmneb see mikrostruktuuris nõelja ferriidi kujul perliiidis. Üleeutektoidteraste puhul avaldub see nõelja tsementiidi kujul. Algselt avastatud meteoriitidel. (vt alaeutektoidteras, üleeutektoid teras, ferriit, perliit, tsemetiit)
  • structure characterized by a geometrical pattern resulting from the formation a new phase along certain crystallographic planes of the parent solid solution
    Good to know
    • In the case of hypoeutectoid steels, it appears in a metallographic section in the form of ferrite needles in a pearlite background. In the hypereutectoid steel, the needles consist of cementite. (see: hypoeutectoid steel, hypereutectoid steel, ferrite, pearlite, cementite)
