Icyuma cya Crankshaft C38N2 ni ubwoko bushya bwibyuma bito bito kandi bidafite ubushyuhe, bisimbuza ibyuma byazimye kandi bituje kugirango bikore moteri ya Renault. Inenge yimisatsi yubuso ni inenge zisanzwe mubuzima bwa crankshafts, ahanini ziterwa nubusembwa bwa metallurgjiya nka pore hamwe nubunebwe muri ingot yumwimerere bikururwa kuva mukibanza kugeza hejuru mugihe cyo guhimba. Kunoza ubwiza bwibanze bwibikoresho bya crankshaft byabaye intego yingenzi mugikorwa cyo kuzunguruka. Mugabanye koroshya inzira mugihe cyo kuzunguruka, no guteza imbere ihindagurika ryibanze nuburyo bwiza bwo kwidegembya no kugabanuka kwintangiriro yimiterere yabasudira.

Intiti zo muri kaminuza y’ubumenyi n’ikoranabuhanga Beijing zize ku ngaruka ziterwa n’imiterere y’imiterere, ubushyuhe bw’imiterere, igipimo cy’imiterere, umubare w’imiterere, hamwe n’intera intera ku cyuma kitazimye kandi gifite ubushyuhe C38N2 kizunguruka cya crankshafts binyuze mu bushakashatsi bwo kwigana ubushyuhe, metallography optique no kohereza microscopi ya electron. Itegeko ryingaruka za static recrystallisation agace kangana nigipimo gisigaye hagati ya passes.

Ibisubizo byubushakashatsi byerekana ko hamwe no kwiyongera kwubushyuhe bwo guhindura ibintu, igipimo cyo guhindura ibintu, umubare woguhindura cyangwa igihe kiri hagati ya passes, agace kangana na static rerystallisation gahoro gahoro gahoro gahoro, kandi igipimo gisigaye cya passe kigabanuka. ; Ingano yumwimerere ya austenite yiyongera, kandi igice cya static rerystallisation igabanuka, ariko impinduka ntabwo ari ngombwa; munsi ya 1250 ℃, hamwe nubushyuhe bwo kongera ubushyuhe bwiyongera, agace ka static rerystallisation ntigabanuka cyane, ariko Hejuru ya 1250 ℃, kwiyongera kwubushyuhe bukabije biragaragara ko bigabanya igice cyinshi cya static. Binyuze kumurongo ukwiranye nuburyo buto bwa kare, uburyo bw'imibare yerekana isano iri hagati ya static recrystallisation ingano yibice hamwe nibice bitandukanye byo guhindura ibintu byabonetse; igipimo cyibisigisigi cyibisigisigi byimibare isubirwamo, kandi igipimo cyibisigisigi cyimibare yimibare ikubiyemo igipimo cyibipimo byabonetse.
