I-16Mn yomgangatho ophezulu wensimbi engenamthungo umenzi wepayipi yomenzi indawo
(1) Umgangatho ophezulu wekhabhoni yezakhiwo zentsimbi zibandakanya i-20g, i-20mng kunye ne-25mng.
(2) I-alloy yezakhiwo zentsimbi: 15mog, 20mog, 12crmog, 15CrMoG, 12CR2MOG, 12crmovg, 12Cr3MoVSiTiB, njl.
(3)Ukongeza ekuqinisekiseni ukwakheka kweekhemikhali kunye neempawu zoomatshini, i-1Cr18Ni9 kunye ne-1cr18ni11nb iityhubhu zebhoyila eziqhele ukusetyenziswa kwintsimbi erusayo ekwaziyo ukumelana nobushushu ziya kuxhomekeka kuvavanyo lwe-hydrostatic, ukugqabhuka kunye novavanyo lokucaba nganye nganye. Imibhobho yentsimbi iya kuhanjiswa kwimeko yokuphathwa bubushushu.
(1)I-Gb3087-2008 iityhubhu zensimbi ezingenamthungo kwiibhoyili eziphantsi kunye neziphakathi. Uvavanyo lwe-tensile luya kuhambelana ne-GB / t228-87, uvavanyo lwe-hydrostatic kunye ne-GB / t241-90, uvavanyo lwe-flatening kunye ne-GB / t246-97, uvavanyo lwe-flaring kunye ne-GB / t242-97 kunye novavanyo lokugoba olubandayo kunye ne-gb244-97.
(2)I-GB5310-2008 iityhubhu zentsimbi ezingenamthungo kwiibhoyili zoxinzelelo oluphezulu. Uvavanyo lwe-tensile, uvavanyo lwe-hydraulic kunye novavanyo lwe-flattening ziyafana nezo zichazwe kwi-gb3087-82; Uvavanyo lwempembelelo ngokwe-gb229-94, uvavanyo lokuvutha ngokwe-GB / t242-97 kunye novavanyo lobungakanani benkozo ngokweYb / t5148-93; Ukuhlolwa kwe-Microstructure kuya kuhambelana ne-gb13298-91, ukuhlolwa kwe-decarburized layer kuya kuhambelana ne-gb224-87, kunye nokuhlolwa kwe-ultrasonic kuya kuhambelana ne-GB / t5777-96.
(3) Ukuhlolwa kokusebenza komzimba kunye nezalathisi zeetyhubhu zebhoyila ezithunyelwa ngaphandle ziya kwenziwa ngokuhambelana nemigangatho efanelekileyo echazwe kwisivumelwano.
Amandla aphezulu (FB) athwalwa yisampulu ngexesha lokuphuka kwe-tensile luxinzelelo olufunyenwe kwindawo yokuqala ye-cross-sectional (so) yesampulu ((σ)， Ebizwa ngokuba yi-tensile strength (σ b) , kwi-N / mm2 (MPA) . Imele amandla aphezulu ezinto zetsimbi ukuxhathisa ukungaphumeleli phantsi koxinzelelo. Ifomula yokubala yile:
Apho: FB -- awona mandla aphezulu athwalwa yisampuli xa yaphukile, n (Newton); Ke -- indawo yoqobo enqamlezileyo yesampulu, mm2.
Kwiimathiriyeli zetsimbi kunye nesiganeko sokuvunwa, uxinzelelo xa i-specimen ingaqhubeka ikhula ngaphandle kokunyuka (ukugcina rhoqo) uxinzelelo ngexesha lenkqubo ye-tensile ibizwa ngokuba yi-isivuno point. Ukuba uxinzelelo luyehla, amanqaku aphezulu kunye asezantsi esivuno aya kwahlulwa. Iyunithi yenqaku lesivuno ngu-n / mm2 (MPA).
Inqaku lesivuno esiphezulu (σ Su):uxinzelelo olukhulu phambi kokuba uxinzelelo lwesivuno lwesampulu luyancipha okokuqala; Inqanaba lesivuno esisezantsi (σ SL): ubuncinci boxinzelelo kwinqanaba lesivuno xa isiphumo sokuqala sangoko singaqwalaselwa.
Ifomyula yokubala yenqaku lesivuno yile:
Apho: I-FS -- isivuno soxinzelelo (oluqhubekayo) lwesampulu ngexesha loxinzelelo, n (Newton) ngoko - indawo yokuqala ye-cross-sectional yesampuli, mm2.
