Hali ya utoaji
Uteuzi | Alama | Maelezo |
Baridi imekamilika (ngumu) | BK(+C) | Mirija haifanyi matibabu ya joto kufuatia uundaji wa baridi ya mwisho na, kwa hivyo, ina upinzani wa juu kwa deformation |
Baridi imekamilika (Laini) | BKW | Matibabu ya mwisho ya joto hufuatiwa na kuchora baridi inayohusisha deformation ndogo.Usindikaji zaidi unaofaa huruhusu kiwango fulani cha uundaji baridi (kwa mfano, kupinda, kupanua) |
(+LC) | ||
Baridi imekamilika na kupunguza mkazo | BKS(+SR) | Matibabu ya joto hutumiwa kufuatia mchakato wa mwisho wa kuunda baridi.Kwa kuzingatia hali zinazofaa za usindikaji, ongezeko la mikazo ya mabaki inayohusika huwezesha kuunda na kutengeneza kwa kiwango fulani. |
Annealed | GBK(+A) | Mchakato wa mwisho wa kuunda Baridi hufuatwa na kuingizwa kwenye angahewa iliyodhibitiwa. |
Imesawazishwa | NBK(+N) | Mchakato wa mwisho wa uundaji wa baridi hufuatwa na kuingizwa juu ya sehemu ya juu ya mabadiliko katika anga inayodhibitiwa. |
