168 ʻUpena forgings: he aha nā hana annealing no ka forgings?

Forgings o ka annealing kaʻina e like me ka haku mele 'ana o ka okoa annealing kumu, hiki ke maheleia i piha annealing incomplete homogenizing annealing spheroidizing annealing (homogenizing annealing) i stress annealing a me isothermal annealing recrystallization annealing laulā o ka noi:

(1) piha annealing kaʻina o waena kalapona kila kalapona kiʻekiʻe hoʻoheheʻe kila kila o carbon ma haʻahaʻa hoʻoheheʻe kila weldments forgings olokaʻi ʻāpana e like me annealing lapaʻau piha annealing o

a. B hoʻomaikaʻi i ke ʻano o ka palaoa mānoanoa, hoʻomaʻemaʻe i ka palaoa, hoʻopau i ka ʻōnaehana widmanstatten a me ka hoʻolālā banded;

B. E ho'ēmi i ka paʻakikī a hoʻomaikaʻi i ka hana ʻoki;

C. Hoʻopau i ke kaumaha o loko;

D. Hiki ke hoʻohana ʻia e like me ka hoʻomaʻamaʻa wela hope no nā ʻāpana koʻikoʻi.

(2) Kaʻina hana annealing piha ʻole

Ka laulā noi: ke kila subeutectoid, ke kila kalapona kalapona, ke kila kila kila, ke kila kila haʻahaʻa, ke kila kila haʻahaʻa a me ke kila hypereutectoid, nā'āpana'ōwili wela a pēlā aku.
ʻO ke kumu hoʻohui piha ʻole: e hoʻopau i ke koʻikoʻi o loko o ka forging a me ka ʻōwili ʻana, hoʻemi i ka paʻakikī, hoʻomaikaʻi i ka paʻakikī.

(3) Spheroidizing annealing
Ka laulā o ka noi:
A. Hoʻomākaukau wela ka mālama ʻana i ke kila hypereutectoid e like me ke kila kila a me ke kila mea hana;
B. Cold deformed forging annealing treatment of medium and low carbon steels and medium and low carbon alloy steels.
ʻO ke kumu o ka spheroidizing annealing
A. No nā forgings e koi ana i ka ʻokiʻoki, e hoʻemi i ka paʻakikī a hoʻomaikaʻi i ka hana ʻoki;
B. No ke anu deformation workpiece me kaʻokiʻole, hoʻomaikaʻi i ka plasticity o ke anu deformation workpiece;
C. Spheroidized carbide e pale i ka overheating ma hope o ke kinai ʻana a hoʻomākaukau no ke kanu ʻana ma kahi wela hope;
[D] Hoʻopau i ke kaumaha o loko.

(4) Isothermal annealing
ʻO ka noi ʻana i ka isothermal annealing: ke kila make, ka hoʻopaʻa ʻana i ke kila kila, nā ʻāpana stamping.
ʻO nā mea maikaʻi o ka isothermal annealing: hiki ke hoʻopōkole i ka pōʻaiapili annealing, hoʻemi i ke kumukūʻai hana.
