Qib 1 thiab Qib 2 yog qhov siv dav tshaj plawsKev lag luam ntshiab titanium (CP Ti)Cov qib hauv kev lag luam thiab aerospace kev siv, txhais los ntawm cov qauv xws li ASTM B265 (phaj / ntawv / foils), ASTM B348 (bars), thiab ISO 5832-2. Lawv qhov sib txawv tseem ceeb yog nyob rau hauv cov ntsiab lus ntawm cov ntsiab lus (oxygen, nitrogen, carbon) thiab impurity txwv, uas cuam tshuam ncaj qha rau cov khoom siv kho tshuab thiab kev thov kom haum. Hauv qab no yog ib daim ntawv qhia dav dav:
1. Core Chemical Composition Differences
Ob Qib 1 thiab Qib 2 raug cais raws li "tsis muaj titanium," txhais tau tias lawv lub hauv paus muaj pes tsawg leeg yog feem ntau titanium nrog cov ntsiab lus tsis tshua muaj siab. Cov kev sib txawv tseem ceeb yog nyob rau hauvtso cai txwv ntawm cov ntsiab lus interstitial (O, N, C)thiab impurity element hlau (Fe)-cov ntsiab lus no tsis muaj nyob hauv kev tsim khoom tab sis tswj nruj kom ntseeg tau tias kev ua haujlwm zoo ib yam.
| Qeb Element | Qib 1 yam ntxwv | Qib 2 yam ntxwv |
|---|---|---|
| Cov ntsiab lus Interstitial (O, N, C) | Tsawg cov ntsiab lus txwv (tseem ceeb rau ductility) | Cov ntsiab lus siab dua (txhim kho lub zog) |
| Cov ntsiab lus impurity (Fe) | Kev txwv nruj (txo kev pheej hmoo ntawm nkig theem) | Ntau qhov kev txwv tsis pub muaj zog (mos boosts hardness) |
| Hydrogen (H) | Kev txwv tsis sib xws (tsawg dua lossis sib npaug rau 0.015% ib ASTM) - H yog tswj nruj kom tiv thaiv hydrogen embrittlement | Kev txwv tsis sib xws (tsawg dua lossis sib npaug rau 0.015% ib ASTM) |
| Lwm yam impurities(eg, Si, Al, V) | Tag nrho cov kab impurities Tsawg dua los yog sib npaug rau 0.30% | Tag nrho cov kab impurities Tsawg dua lossis sib npaug li 0.30% (ib yam li Qib 1) |
Kev cuam tshuam tseem ceeb: Interstitial cov ntsiab lus (tshwj xeeb tshaj yog cov pa oxygen) ua raws li "cov khoom siv dag zog"- cov ntsiab lus oxygen siab dua hauv Qib 2 ua rau muaj zog tensile thiab hardness tab sis me ntsis txo ductility thiab formability piv rau Qib 1.
2. Titanium Purity (Lub hauv paus hlau ntsiab lus)
Purity yog txhais raws li qhovfeem pua ntawm titanium (Ti) nyob rau hauv tag nrho cov muaj pes tsawg leeg, tsis suav nrog cov ntsiab lus interstitial (O, N, C, H) thiab impurities (Fe, Si, thiab lwm yam). Purity ncaj qha cuam tshuam nrog formability: siab dua purity=zoo dua ductility thiab weldability.
| Qib | Yam tsawg kawg nkaus Titanium Purity (ASTM Standard) | Cov Lus Qhia Ntxiv |
|---|---|---|
| Qib 1 | Ntau dua lossis sib npaug li 99.5% | Qhov siab tshaj plaws purity ntawm CP Ti qib. Ultra- cov ntsiab lus tsis tshua muaj kev cuam tshuam / impurity ua rau muaj qhov tshwj xeeb txias txias (piv txwv li, kos duab sib sib zog nqus, khoov) thiab tiv thaiv kev ntxhov siab corrosion tawg (SCC). |
| Qib 2 | Ntau dua lossis sib npaug li 98.9% (Feem ntau 99.0–99.4%) | Tsawg purity me ntsis vim muaj ntau dua O / Fe txwv. Sib npaug lub zog thiab formability, ua rau nws muaj ntau yam CP Ti qib rau kev siv engineering. |
3. Oxygen (O) thiab Hlau (Fe) Cov ntsiab lus txwv
Oxygen thiab hlau yog cov khoom tseem ceeb tshaj plaws hauv CP Ti-oxygen dominates zog txhim khu kev qha, thaum hlau ua raws li qhov thib ob ntxiv dag zog thiab impurity. Hauv qab noTxheem txwv rau ASTM B265(tus qauv siv dav tshaj plaws rau CP Ti cov khoom lag luam thoob ntiaj teb):
| Element | Qib 1 Kev txwv siab tshaj (ASTM) | Qib 2 Kev txwv siab tshaj (ASTM) | Qhov laj thawj rau qhov txawv |
|---|---|---|---|
| Cov pa oxygen (O) | Tsawg dua los yog sib npaug li 0.18% (qhov loj me) | Tsawg dua los yog sib npaug li 0.25% (qhov loj me) | Oxygen yog lub zog tseem ceeb: Qib 2 qhov siab dua O txwv kom nce tensile lub zog los ntawm ~ 20-30% piv rau Qib 1. |
| Hlau (Fe) | Tsawg dua los yog sib npaug rau 0.20% (ntau feem) | Tsawg dua los yog sib npaug rau 0.30% (qhov loj me) | Hlau txhim kho hardness thiab hnav tsis kam, tab sis tuaj yeem txo cov ductility ntawm qib siab. Qib 2 qhov siab dua Fe txwv ntsuas lub zog thiab kev ua tiav. |
