O le fa'agasologa o le fa'amaluluina ofa'ailogae mafai ona vaevaeina i le fa'amuta atoa, fa'ato'a fa'ato'a, fa'a'ele'ele fa'atasi, fa'ama'i fa'asalalau (fa'ato'a fa'ameamea), fa'ama'i fa'a-isothermal, fa'ama'i fa'amamafa ma fa'amaufa'ailoga e fa'atatau i le tu'ufa'atasiga, mana'oga ma le fa'amoemoega o le fa'atosina.
(1) fa'ato'a mae'a fa'agasologa
①Talosaga lautele:u'amea kaponi feololo, fa'ameamea u'amea fa'ameamea maualuga, fa'ameamea u'amea fa'ameamea maualalo, vaega uelo,fa'ailoga, vaega ta'avale ma isi togafitiga fa'amalulu.
② Fa'amalo uma B
A. Faʻaleleia le fausaga o fatu, faʻamamaina le tele o saito, faʻaumatia le fausaga o Widmannian ma le faʻapipiʻi fusi;
B. Faʻaitiitia le maaa ma faʻaleleia le faʻatinoina o le tipiina;
C. Ave'ese le fa'alavelave i totonu;
D. Fa'ai'uga fa'avevela mo vaega e le taua.

(2) Fa'ato'a mae'a fa'agasologa
①Talosaga lautele:togafitiga annealing o uamea hypoeutectoid, uamea fausaga carbon, uamea uaea carbon uamea, uamea faumea u'amea maualalo, uamea meafaigaluega u'amea maualalo ma hyeutectoid uamea forgings, vaega ta'ai vevela, ma isi.
②Fa'amoemoega o le fa'ama'i le atoatoa:e faʻaumatia ai le faʻalavelave i totonu o le faʻafefeteina o taʻavale, faʻaitiitia le maaa ma faʻaleleia le malosi.

(3) spheroidizing annealing
①Talosaga lautele:
A. Sauniuniga ma togafitiga vevela o u'amea ma mea faigaluega uamea ma isi uamea hypereutectoid;
B. Cold deformation forging annealing treatment of medium and low carbon steels ma medium and low carbon alloy steels.
②O le faʻamoemoega o le faʻaogaina o le spheroidizing:
A. Mofa'ailogae tatau ona tipi, faʻaitiitia le maaa ma faʻaleleia le faʻatinoina o le tipiina;
B. Faʻaleleia le palasitika o mea faigaluega malulu-deformed e aunoa ma le tipiina;
C. Spherical carbide e puipuia ai le soona vevela o le tineia mulimuli ane ma saunia mo le tanuga vevela mulimuli;
D. Aveese le atuatuvale i totonu.
(4) Isothermal annealing
①Talosaga o le isothermal annealing:u'amea pa'u, fa'amea fa'ameamea fa'ameamea, fa'ailoga vaega.
②O le lelei o le isothermal annealing:e mafai ona faapuupuuina le taamilosaga annealing ma faaitiitia le tau o le gaosiga.
