| Ubude | 6m ubude obuzinzileyo | ||
| Ubunzima bodonga lwegama (mm) | 2.0, 2.5, 2.8, 3.2, 3.5, 3.8, 4.0, 4.5 |
1.Amandla okuqina (σb): Awona mandla aphezulu (Fb) athi umfuziselo utyhutyhe xa utsalwa, wahlulwe luxinzelelo (σ) olufunyenwe kwindawo yokuqala yecandelo elinqamlezileyo (So) lomzekelo, kuthiwa amandla okuqina ( σ ) σb), kwi-N/mm2 (MPa).Imele umthamo omkhulu wezinto zetsimbi ukuxhathisa umonakalo phantsi koxinzelelo.Apho: Fb - awona mandla aphezulu umfuziselo umelana nawo xa utsalwa, N (Newton);Ngoko - indawo yokuqala ye-cross-sectional ye-specimen, mm2.
2.inqanaba lesivuno (σs): izinto zetsimbi kunye nesiganeko sokuvunwa, uxinzelelo xa i-specimen ingaqhubeka ikhula ngaphandle kokunyuka kwamandla (ihlala ihleli) ngexesha lenkqubo yokwelula, ebizwa ngokuba yi-chield point.Ukuba amandla ayancipha, amanqaku aphezulu kunye nasezantsi kufuneka ahlulwe.Iyunithi yenqaku lesivuno yi-N/mm2 (MPa).Inqaku lesivuno esiphezulu (σsu): ubuninzi boxinzelelo ngaphambi kokuba i-specimen ivelise kwaye amandla kuqala ayancipha;Inqaku lesivuno esisezantsi (σsl): ubuncinci boxinzelelo kwisigaba sokunikezela xa isiphumo sokuqala sexeshana singabalwa.Apho: Fs - isivuno samandla (ngokuqhubekayo) somzekelo kwi-tension, N (Newton) Ngoko - indawo yokuqala yecandelo lomnqamlezo womzekelo, mm2.
3.Ukwandiswa emva kwekhefu: (σ) Kuvavanyo lwe-tensile, ipesenti yokunyuka kubude bomzekelo emva kokutsala isikali sayo ukuya kubude besikali sokuqala kuthiwa yi-elongation.Ichazwe ngo-σ, iyunithi yi-%.Kuphi: L1 - ubude bomzekelo emva kokuba umboniso utsaliwe, mm;I-L0 - ubude be-pitch yokuqala ye-specimen, mm.
4.I-Fractional shrinkage: (ψ) Kuvavanyo lwe-tensile, ubuninzi be-shrinkage yendawo ye-cross-sectional kwi-shrinkage yayo emva kokuba i-specimen ikhutshwe njengepesenti yendawo yokuqala ye-cross-sectional ebizwa ngokuba yi-fractional shrinkage.Libonakaliswe njengo-ψ, nge-%.Apho: I-S0 - indawo yokuqala ye-cross-sectional ye-specimen, mm2;I-S1 - indawo encinci ye-cross-sectional kwi-shrinkage emva kokuba i-specimen ikhutshwe, mm2.
5.Ukuqina kwesalathiso: Ukukwazi kwesixhobo sentsimbi ukuxhathisa ukufakwa kwento eqinileyo kumphezulu, ebizwa ngokuba bubulukhuni.Ngokuxhomekeke kwindlela yovavanyo kunye nobubanzi besicelo, ubulukhuni bunokwahlulwa bubulukhuni beBrinell, ukuqina kweRockwell, ukuqina kweVickers, ukuqina konxweme, ubulukhuni obuncinci kunye nobunzima obuphezulu bobushushu.Kuba ityhubhu isetyenziswa ngokubanzi kwiBrinell, Rockwell, Vickers ubulukhuni abathathu.
I-Brinell hardness (HB): Ukusebenzisa intsimbi okanye ibhola ye-carbide yobubanzi obuthile, cinezela amandla ovavanyo oluchaziweyo (F) kumphezulu womfanekiso, susa amandla ovavanyo emva kwexesha elichaziweyo lokubamba, kwaye ulinganise i-indentition diameter (L) kumphezulu womzekelo.Ixabiso le-Brinell hardness yi-quotient efunyenwe ngokwahlula amandla ovavanyo ngendawo engqukuva yomphezulu we-indent.Ibonakaliswe njenge-HBS (ibhola yentsimbi) nge-N/mm2 (MPa).
Imibhobho yentsimbi eshushu-diphu isetyenziswa ngokubanzi kulwakhiwo, oomatshini, imigodi yamalahle, kushishino lwemichiza, amandla ombane, izithuthi zikaloliwe, ishishini lemoto, oohola bendlela, iibhulorho, izitya, izibonelelo zemidlalo, oomatshini bezolimo, oomatshini bepetroleum, oomatshini bokukhangela kunye namanye amashishini okuvelisa. .
Umbhobho wentsimbi owenziwe ngesinyithi ngumbhobho wentsimbi odityanisiweyo onediphu eshushu okanye umphezulu we-electro galvanized.I-galvanization inokunyusa ukuxhatshazwa kwe-corrosion yeepayipi zensimbi kunye nokwandisa ubomi benkonzo.Umbhobho wentsimbi owenziwe ngesinyithi unoluhlu olubanzi lwezinto ezisetyenziswayo, ukongeza ekusebenziseni njengombhobho kulwelo oluphantsi loxinzelelo jikelele olufana namanzi, igesi neoyile, ukwasetyenziswa njengombhobho we-oyile kunye nombhobho we-oyile kushishino lwepetroleum, ngakumbi amasimi e-oyile yolwandle, njengesifudumezi se-oyile, i-condensation epholileyo kunye ne-distillation yamalahle kunye ne-oyile yokuhlamba i-oyile yezixhobo zokucoca iikhemikhali, kunye nombhobho wesakhelo senkxaso kwiimfumba zemibhobho ye-trestle kunye nemigodi yemigodi, njl.
Umbhobho wamanzi, umbhobho we-oyile, umbhobho wesikafula, ucingo lohola wendlela, isigqubuthelo seshedi, njl.
