16Mn ubuziranenge bwo hejuru butagira ibyuma bikora uruganda rukora
(1) Ibyiciro byiza bya karubone byubatswe mubyiciro birimo 20g, 20mng na 25mng.
(2) Alloy ibyuma byubaka ibyiciro: 15mog, 20mog, 12crmog, 15CrMoG, 12CR2MOG, 12crmovg, 12Cr3MoVSiTiB, nibindi.
(3)Usibye kwemeza imiterere yimiti nubukanishi, 1Cr18Ni9 na 1cr18ni11nb itekesha ibyuka bikunze gukoreshwa mubyuma bitarwanya ubushyuhe bugomba gukorerwa ibizamini bya hydrostatike, gutwika no gusibanganya umwe umwe. Imiyoboro y'icyuma igomba gutangwa muburyo butunganijwe.
(1)Gb3087-2008 ibyuma bitagira ibyuma kubitereko bito kandi biciriritse. Ikizamini cya Tensile kigomba kubahiriza GB / t228-87, ikizamini cya hydrostatike hamwe na GB / t241-90, ikizamini cyo gusibanganya GB / t246-97, ikizamini cyo gutwika hamwe na GB / t242-97 hamwe n'ikizamini cyo gukonjesha hamwe na gb244-97.
(2)GB5310-2008 ibyuma bidafite ibyuma kubitereko byumuvuduko mwinshi. Ikizamini cya Tensile, ikizamini cya hydraulic hamwe na test ya flating ni kimwe nibisobanuwe muri gb3087-82; Ikizamini cyingaruka ukurikije gb229-94, ikizamini cyaka ukurikije GB / t242-97 hamwe nubunini bwingano ukurikije Yb / t5148-93; Igenzura rya microstructure rigomba gukurikiza gb13298-91, ubugenzuzi bwa decarburize bugomba gukurikiza gb224-87, naho ubugenzuzi bwa ultrasonic bugakurikiza GB / t5777-96.
(3) Igenzura ryimikorere nigipimo cyibikoresho bitumizwa mu mahanga bigomba gukorwa hakurikijwe ibipimo bijyanye n'amasezerano.
Imbaraga ntarengwa (FB) zitwarwa nicyitegererezo mugihe cyo gucika intege ni imihangayiko yakuwe mu gice cyambere cyambukiranya ibice (so) by'icyitegererezo （(σ) ， Yitwa imbaraga zingana (σ b), muri N / mm2 (MPA) . Yerekana ubushobozi ntarengwa bwibikoresho byibyuma byo kunanirwa kunanirwa. Inzira yo kubara ni:
Aho: FB - imbaraga ntarengwa zitwarwa nicyitegererezo iyo zacitse, n (Newton); Noneho - umwimerere wambukiranya igice cyicyitegererezo, mm2.
Kubikoresho byibyuma bifite umusaruro mwinshi, guhangayika mugihe urugero rushobora gukomeza kuramba bitiyongereye (kugumya guhora) guhangayika mugihe cyibihe byiswe umusaruro. Niba imihangayiko igabanutse, ingingo zo hejuru no hepfo zitanga umusaruro. Igice cy'umusaruro ni n / mm2 (MPA).
Umusaruro wo hejuru （σ Su):imihangayiko ntarengwa mbere yumusaruro wintangarugero ugabanuka kunshuro yambere; Ingingo yo gutanga umusaruro muke (σ SL): guhangayikishwa byibuze murwego rwo gutanga umusaruro mugihe ingaruka zambere ako kanya zidasuzumwe.
Ibiharuro byo kubara umusaruro ni:
Aho: FS - gutanga umusaruro (guhoraho) by'icyitegererezo mugihe cy'impagarara, n (Newton) bityo - umwimerere wambukiranya igice cy'icyitegererezo, mm2.
