Aruminiyamu itsva ine simba guru rekugadzira zvinhu: chinhu chakakosha chekugadzirisa mwenje wemotokari uye kugadzirisa mashandiro ayo
Mhedzisiro yekutsvagisa yazvino inoratidza hunhu hwakanaka hweAl-Si-Mg-Mn alloy
Mukuenderera mberi kwekuvandudzwa kweindasitiri yemotokari, kupenya kwechiedza kwave nzira yakakosha yekuvandudza mashandiro esimba uye kushanda zvakanaka. Sechinhu chakareruka uye chine simba guru, aruminiyamu iri kushandiswa zvakanyanya mukugadzira mota. Munguva pfupi yapfuura, chidzidzo pamusoro pearuminiyamu itsva ine simba guru yeAl-Si-Mg-Mn chinopa maonero matsva pamusoro pekushandiswa kwearuminiyamu alloys mukuona kwechiedza chemotokari.
Hunhu hwebudiriro yeAl-Si-Mg-Mn alloy itsva
Sekureva kwetsvagurudzo yazvino, simba rekudhonza reAl-Si-Mg-Mn alloy itsva mushure mekuumbwa kwesimbi (seyakakandwa) rinogona kusvika 230 kusvika 310 MPa, simba rekukohwa i200 kusvika 240 MPa, uye kureba kuri pamusoro pe0.5%. Kuonekwa kwekushanda uku kunobatsira kubva pakuumbwa kwefaini. a-AlFeMnSi phase uye multi-scale eutectic structure mu alloy. Zvisinei, kureba kwe alloy kwakaderera, kunyanya nekuda kwekukanganiswa kwakananga kwema pores akakura uye coarse second phases.
Kushandiswa kwetekinoroji yekukanda zvinhu nekugadzira aruminiyamu
Senzira yekuumba mota, kukanda masimbi kunoshandiswa zvakanyanya mukugadzira mota, kutaurirana, michina yeinjiniya nezvimwe zvikamu nekuda kwekushanda kwayo kwepamusoro, kunyatsogadzirwa kwezvigadzirwa uye kushanda zvakanaka. Mumakore gumi apfuura, zvikamu zvakawanda zvemotokari zvakatanga kugadzirwa nesimbi zvakatsiviwa nezvikamu zvealuminium alloy die-casting, izvo zvisingangoderedzi huremu hwemotokari chete, asiwo zvinozadzisa zvinangwa zvekuchengetedza simba uye kuderedza utsi.
Kusimbisa mashandiro uye kuvandudza mashandiro ealuminium alloys
Kuwedzera zvinhu zvakaita seMg, Cu, Mn kana Zn muaruminiyamu alloys kuti zvigadzire makemikari ari pakati akadai seAlMgZn, AlMn kana Al2Cu kunogona kuvandudza simba realloy. Kusimbaradzwa kwealloys idzi kunokonzerwa nekusimba kwemvura uye kusimba kwemvura. Tsvagiridzo inoratidza kuti nekuwedzera huwandu hwakakodzera hweMn, kwete chete kuti ganda rinonamira rinogona kuderedzwa, asiwo chimiro chealloy. bChikamu che -Fe chinogonawo kuchinjwa, zvichiwedzera kuvandudza mashandiro e alloy.
Tsvagiridzo pamusoro pemaumbirwo uye hunhu hwearuminiyamu itsva
Vaongorori vakagadzira Al-Si-Mg-Mn alloy compositions ine zvikamu zvakasiyana zve eutectic integral fractions kuburikidza neJMatPro phase diagram simulation calculations. Kuburikidza ne microstructure observation uye fracture morphology analysis, kushanduka kwechimiro uye mashandiro e alloy zvakaratidzwa. Tsvagiridzo yakawana kuti ultrafine eutectic structures dzinogona kuvandudza zvakanyanya simba uye plasticity ye alloys, zvichipa nzira itsva yekuvandudza mashandiro e alloys dze aluminum.
