Forgings o le faagasologa o le annealing e tusa ai ma manaoga o le tuufaatasiga o faamoemoega annealing eseese, e mafai ona vaevaeina i atoatoa annealing le atoatoa homogenizing annealing spheroidizing annealing (homogenizing annealing) e faamamafa annealing ma isothermal annealing recrystallization annealing lautele lautele o le talosaga:
a.B faʻaleleia le fausaga mafiafia o fatu, faʻamamaina le saito, faʻaumatia le fausaga widmanstatten ma le faʻapipiʻi fusi;
B. Faʻaitiitia le maaa ma faʻaleleia le faʻatinoina o le tipiina;
C. Ave'ese le fa'alavelave i totonu;
D. E mafai ona faʻaaogaina e avea ma togafitiga vevela mulimuli mo vaega le taua.
(2) Fa'ato'a mae'a fa'agasologa
Talosaga lautele: u'amea subeutectoid, uamea fausaga carbon, uamea uaea uaea uamea, uamea fausaga u'amea maualalo, uamea meafaigaluega u'amea maualalo ma uamea hypereutectoid forging, vevela lo'o fasi ma isi togafitiga annealing.
Fa'ato'a fa'atosina fa'amoemoe: e fa'aumatia ai le fa'alavelave fa'alotoifale o le ta'avale ma le ta'avale, fa'aitiitia le faigata, fa'aleleia le malosi.
(3) Spheroidizing annealing
Avanoa o le talosaga:
A. Sauniuniga vevela togafitiga o hypereutectoid sila e pei o le tauaveina uamea ma meafaigaluega uamea;
B. Cold deformed forging annealing treatment of medium and low carbon steels and medium and low carbon alloy steels.
O le fa'amoemoega o le fa'ama'i fa'a-spheroidizing
A. Mo forgings e manaʻomia le tipiina, faʻaitiitia le faigata ma faʻaleleia le faʻatinoina o le tipiina;
B. Mo le malulu deformation workpiece e aunoa ma le tipiina, faaleleia le plasticity o le malulu deformation workpiece;
C. Spheroidized carbide e puipuia ai le vevela pe a uma ona tineia ma sauni mo le tanu i le nofoaga vevela mulimuli;
[D] Aveese le atuatuvale i totonu.
(4) Isothermal annealing
Isothermal annealing talosaga: u'amea mate, u'amea u'amea u'amea, fa'ailoga vaega.
Le lelei o le isothermal annealing: e mafai ona faapuupuuina le taamilosaga annealing, faaitiitia le tau o le gaosiga.
