The carbide forming elements are also distributed into matrix according to their distribution coefficients to austenite and give effects on the matrix transformation during heat treatment.
Phase transformation behavior obtained from the CCT curves gave useful instructions to the heat treatment process.
The continuous cooling transformation (CCT) curves obtained by cooling from austenitizing temperatures of 1273 K and 1373 K after annealing at 1223 K for 18 ks were investigated.
