Ukuziphatha Kwezinguquko ze-Bainite Kwensimbi eyi-100Cr6 Ukunikela

I-high-carbon chromium 100Cr6 ene-steel, ebala inani elikhulu kakhulu emakethe, inesakhiwo esijwayelekile se-high-carbon twin martensite + carbide + egcinwe i-austenite uma isetshenziswa. Ngokuthuthukiswa komkhakha wokuthwala, izidingo zokusebenza zensimbi ethwele ziye zaba nzima kakhulu. Ngokususelwa ekuthuthukisweni kwezakhiwo ezibonakalayo ezilethwe yisakhiwo se-bainite, indlela yokwelashwa ye-bainite isothermal yokuthwala insimbi ifanele ukwandiswa nokusetshenziswa.

Ngaphandle kokuthinta ukusebenza kokugcina kwensimbi ethwele, izifundiswa zinentshisekelo enkulu yokuthi singasinciphisa kanjani isikhathi sokukhushulwa senguquko engapheli. Sebenzisa izakhiwo ezizuzisayo zesakhiwo se-bainite isothermal ukwenza ngcono inqubo yokwehlisa isikhathi sokuguquka kwesigaba. Ngokuya ngombono we-thermodynamics kanye ne-dynamics microstructure control, le phrojekthi yafunda umthetho wesigaba sokuziphendukela kwemvelo we-100Cr6 ophethe insimbi ngesikhathi sokwelashwa kwe-isothermal, futhi yaphakamisa indlela yokwelashwa ye-bainite yesikhashana.
    
Izinto zokuhlola zikhethwa njenge-1.02C-1.49Cr-0.23Si-0.37Mn (ingxenyenamba yesisindo,%) i-carbon chromium ephezulu enensimbi encibilikisiwe esithandweni sokungeniswa se-ZGJL0.05-100-2.5D, kanti isakhiwo sendawo yokushisa siyi-ferrite ngemuva i-spheroidizing annealing Spherical alloy carbides ihlakazekile kumatrix. Ukuhlolwa kokwelashwa kokushisa kwenziwa ku-DIL805A dilatometer. Ngemuva kokushisa kuya ku-860 ° C ngezinga lokushisa elingu-5 ° C / s imizuzu engama-30, yaba yisakhiwo esixubekile se-austenite + esingaxazululwa esiyindilinga esiyindilinga (3%), sabe sesicinywa kokuhlukile Yenza ukwelashwa okungafani ne-isothermal emazingeni okushisa ukuze kufundwe umthetho wokuguqulwa okungapheli kwe-isothermal; xoxa futhi ahlaziye ukuzinza kwama-austenite angapholi ngesikhathi senqubo yoguquko engapheli; iphakamisa inqubo entsha yokwelashwa okuyizigaba ezimbili ye-Fabry; sebenzisa i-ZEISSULTRA55 Thermal field emission scanning electron microscope ukuhlaziywa kwenhlangano; Ucwaningo lwe-Bainite nolwangaphakathi oluhle ku-TecnaiF30 transmission electron microscope; ukuhlaziywa kwempahla ebonakalayo ku-D / MAX-RB12KW ejikeleza i-anode X-ray diffractometer; HVS-1000 digital microscope Test the Vickers hardness on the hardness tester; vivinya ukusebenza kokugqoza okungahambi kahle kumhloli we-nitrate disc abrasion. umphumela ukhombisa:

• Ububanzi bokushisa kwethiphu lekhala lokuguqulwa kwe-bainite isothermal ngu-300 ～ 350 ℃. Uma kubhekwa isikhathi sokuguquguquka kwesigaba kanye nobulukhuni, kuphethwa ngokuthi ukwelashwa kwe-isothermal ku-250 ℃ kuyinkqubo efanelekile. Izinga lokushisa lesigaba esiphansi likhuthaza ukusatshalaliswa okuhle nokuhlakazekile kwezimvula, futhi ama-laths we-bainite akhula ngendlela ethile;
• Okuqukethwe kwe-austenite egcinwe kuphezulu kakhulu lapho kugcinwa ku-250 ° C imizuzu engama-20 bese kupholile ekamelweni lokushisa. Lapho isikhathi sokubamba siphansi kunalokhu, ingxenye ye-austenite ibhekana nokuguqulwa kwemartensite ngesikhathi senqubo yokupholisa; ngemuva kokuthi isikhathi sokubamba singaphezu kwemizuzu engama-20, lapho selehlile ekamelweni lokushisa, i-austenite ayifuni ukuguqulwa kwemartensite;
• Ukucubungula okuyizinyathelo ezimbili kunganciphisa kakhulu isikhathi sokucubungula. Esigabeni sesibili, izinga lokushisa ligcinwa ku-270 ° C imizuzu emihlanu. Isikhathi esiphelele soguquko olunezigaba ezimbili lumayelana ne-5% yaleyo yenqubo ejwayelekile, futhi okuqukethwe okugcinwe kwe-austenite kumayelana ne-27% kuphela, kanti ukusebenza kobulukhuni nokugqoka akwehliswanga kakhulu.
