Habsocodka sifeynta degdegga ah ee foornada kululaynta induction

The kuleylka kuleylka habsocodka sifeynta degdegga ah ee spheroidizing waa hab isku -darka isku -darka oo lagu dhammaystiro austenitizing foornada kululaynta induction iyo marxaladda diyaarinta spheroidizing, iyo marxaladda spheroidizing -ka waxaa dhammaystira kulayl dhaqameedka. Sii ciyaar buuxda sifooyinka labada hababka kululaynta oo isku dar si aad u samaysid hannaan cusub oo dhaqaajin ah oo degdeg ah.

Adeegsiga astaamaha kor u kaca heerkulka degdegga ah ee foornada kululaynta induction for austenitization, crystals bilowga austenite ganaax ah ayaa la helaa, kaas oo abuuraya sharuudaha qaboojinta dambe si loo helo badar fiican. Marka loo eego xaaladaha qaboojinta ee kala duwan ee austenitizing, dhismayaasha horudhaca ah ee kala -goynta kala duwan ayaa la helaa. Unugyada diyaarinta spheroidizing ee kala duwan ayaa la kala -soocaa oo la suuxiyaa iyadoo la adeegsanayo hababka kulaylinta dhaqameedka si ugu dambayn loo helo unugyada is -buufinta.

Marka loo eego xaaladaha qaboojinta ee kala duwan ee austenitizing, qaabka diyaarinta spheroidizing wuxuu u qaybsan yahay saddexda nooc ee soo socda:

(1) Qaab dhismeedka diyaarinta spheroidized ee ay samaysay qaboojinta hawo (caadiyeynta) waa luul.

(2) Qaab -dhismeedka diyaarinta spheroidization -ka oo ay samaysay qaboojinta biyaha (bakhtiinta) waa martensite + austenite.

(3) Qaab -dhismeedka diyaarinta spheroidized ee lagu sameeyay qaboojinta biyaha (kululaynta soo noqnoqota iyo deminka ka sarreeya 400 ° C) waa sorbite.
