APAKAH MAKSUD EUTECTOID dalam CORSICA?
Sistem eutektik
Sistem eutektik dari Greek "ευ" dan "Τήξις" adalah campuran sebatian kimia atau unsur yang mempunyai komposisi kimia tunggal yang menguatkan pada suhu yang lebih rendah daripada komposisi lain yang terdiri daripada bahan yang sama. Komposisi ini dikenali sebagai komposisi eutektik dan suhu di mana ia menguatkan dikenali sebagai suhu eutektik. Pada gambar fasa, persimpangan suhu eutektik dan komposisi eutektik memberikan titik eutektik. Campuran bukan eutektik akan memaparkan pemadatan satu komponen campuran sebelum yang lain. Tidak semua aloi binari mempunyai titik eutektik; contohnya, dalam sistem emas-perak suhu cair dan suhu beku kedua-duanya meningkat secara monotonikal kerana campuran berubah dari perak tulen ke emas tulen.
Definisi eutectoid dalam kamus Corsica
Takrif eutectoid dalam kamus adalah campuran bahan yang serupa dengan eutektik, tetapi membentuk dua atau tiga unsur dari pepejal dan bukan dari cair. Takrifan lain eutectoid berkenaan dengan atau sesuai untuk campuran eutectoid.

In the eutectoid steel the pearlite transformation takes place on cooling to 600-
700°C (1100-1300°F). In this case the plate-to-plate spacing equals 0.5-1 urn.

called as pearlite which consists of alternate layers of ferrite and cementite. Thus
the final ...
