SIGMA(9):
  * $\gamma$ = austenite percentage
  * $P_r$ = proeutectoid percentage
  * $P_e$ = pearlite percentage
  * $B_a$ = bainite percentage
  * $M_a$ = martensite percentage
  * $f_x$, $f_y$ = conductive flow
  * $f_c$ = heat absorbed by the increase of temperature
  * $f_q$ = heat absorbed by phase change
