Ukunyanzeliswa uhlalutyo ibhakethi izinyo ukusebenza ubuso kunye nembiwa zoqhagamshelwano into, kwinkqubo yokomba ngokupheleleyo kwizigaba ezahlukeneyo zokusebenza zoxinzelelo iimeko zayo ezahlukeneyo.Xa incam izinyo kuqala echukumisa umphezulu eziphathekayo, incam izinyo emele ichaphazeleke ngamandla ngenxa isantya salo fast. Ukuba amandla esivuno samazinyo ebhakethi aphantsi, i-deformation yeplastiki iya kwenzeka kwi-tip.Ngokunyuka kokumba ubunzulu, uxinzelelo lwamazinyo ebhakethi luya kutshintsha.Xa into yokusika izinyo lebhakethi, inyosi yebhakethi kunye nezinto ezenzekayo zihambelana nokunyakaza, ivelisa uxinzelelo olukhulu kakhulu lwe-extrusion phezu komphezulu, ngaloo ndlela ivelisa amandla amakhulu okukhuhla phakathi kwezinyo lebhakethi elisebenzayo kunye nezinto eziphathekayo. intshukumo yale nkqubo ivelisa amanqanaba ahlukeneyo okuguga komphezulu kwi-emele izinyo ezisebenzayo, kwaye emva koko ivelise ifolo ngobunzulu obukhulu.Ubude bobomi benkonzo yamazinyo eemele, khetha amazinyo eemele ngokuqinisekileyo ngononophelo ngakumbi utata uthengisa amazinyo eemele Ndasebenzisa amazinyo akhe eemele, umphumo ulungile! , kwaye ubuso obusebenza ngaphambili bugugile kakubi.Inokuthi igwetywe ukuba uxinzelelo olulungileyo kunye namandla okuxhatshazwa yizona zinto ziphambili zangaphandle zomatshini wokungaphumeleli kwamazinyo ebhakethi, adlala indima enkulu kwinkqubo yokungaphumeleli.
Uhlalutyo lwenkqubo: thatha iisampulu ezimbini ukusuka ngaphambili nangasemva zisebenza ubuso ngokulandelelanayo, kwaye uzigaye tyaba ukuze uvavanyo lobulukhuni.Kufunyaniswe ukuba ubulukhuni besampulu efanayo buhluke kakhulu, kwaye isigwebo sokuqala kukuba izinto azifani. iisampulu zagatywa, zaphuculwa kwaye zahlwa, kwaye kwafunyaniswa ukuba kukho imida ecacileyo kwisampulu nganye, kodwa imida yayahluke.Ukusuka kwimbono enkulu, inxalenye ejikelezileyo i-gray ekhanyayo kwaye inxalenye ephakathi imnyama, ebonisa ukuba isiqwenga mhlawumbi yicaste yangaphakathi.Kumphezulu, indawo evalelweyo kufuneka ibe yibhloko efakiweyo.Uvavanyo lobulukhuni kumacala omabini omda lwenziwa kwi-hrs-150 yedijithali umboniso we-rockwell ubulukhuni umvavanyi kunye ne-mhv-2000 yedijithali yokubonisa ubuncinci umvavanyi, kwaye umahluko obonakalayo wafunyanwa. Inxalenye evaliweyo ibhloko yokufaka kwaye inxalenye ejikelezileyo yi-matrix.Ukubunjwa kwezi zibini zifana.Ukubunjwa kwe-alloy ephambili (iqhezu lobuninzi,%) yi-0.38c, 0.91cr, 0.83mn kunye ne-0.92si.Izixhobo zomatshini zezixhobo zetsimbi zixhomekeke ekubunjweni kwazo kunye nenkqubo yonyango lobushushu.Ukubunjwa okufanayo kunye nokwahlukana kobunzima kubonisa ukuba ibhakethi amazinyo asetyenziswa ngaphandle konyango lobushushu emva kokuphoswa.Uqwalaselo lwethishu olulandelayo luqinisekisa oku.
Uhlalutyo lwentlangano yoqwalaselo lwe-metallographic lubonise ukuba i-substrate ubukhulu becala imnyama i-lamellar ecolekileyo, isiqwenga setishu sineenxalenye ezimbini, ibhloko emhlophe emhlophe kunye nemnyama, kunye nebhloko emhlophe kude nombutho wecandelo lomnqamlezo ngakumbi (kunye novavanyo lobuncinci bungqina ukuba umbutho we-ferrite amabala amhlophe, i-lamellar emnyama ecikizekileyo isakhiwo se-troostite okanye i-troostite kunye ne-pearlite hybrid organization.Ukwenziwa kwe-ferrite eninzi kwi-insert ifana neyokweminye imimandla yenguqu yesigaba kwindawo echaphazelekayo yokushisa. ubushushu bolwelo lwesinyithi ngexesha lokugalela, lo mmandla ukwindawo yesigaba se-austenite kunye ne-ferrite, apho i-ferrite ikhule ngokupheleleyo kwaye i-microstructure yayo igcinwa kwiqondo lokushisa. indawo esembindini ibhloko iqondo lokushisa liphantsi, akukho ferrite enkulu yenziwa
Uvavanyo lokugqoka kwi-mld-10 kumatshini wokuvavanya ukugqoka lubonisa ukuba ukunyanzeliswa kokugqoka kwe-matrix kunye nokufaka kungcono kunokucima i-45 yentsimbi phantsi kwemeko yovavanyo oluncinci lwempembelelo. kwaye i-matrix iyakwazi ukumelana nokunxiba kunokufakwa (jonga itafile 2) .Ukwakheka kumacala omabini e-matrix kunye nokufakwa kusondele, ngoko kunokubonwa ukuba ukufakwa kumazinyo ebhakethi ikakhulu ACTS njenge-chiller. inkqubo yokuphosa, ingqolowa ye-matrix isulungekile ukuphucula amandla ayo kunye nokuxhatshazwa kokugqoka.Ngenxa yempembelelo yokushisa okuphosiweyo, isakhiwo sofakelo sifana nelo lobushushu be-welding indawo echaphazelekayo.Ukuba unyango olufanelekileyo lobushushu lwenziwa emva ukuphosa ukuphucula isakhiwo se-matrix kunye nokufaka, ukunyanzeliswa kokugqoka kunye nobomi benkonzo yamazinyo ebhakethi kuya kuphuculwa ngokucacileyo.
