I-alloy entsha ye-aluminium enamandla aphezulu: izinto eziphambili zokukhanyisa iimoto kunye nokuphucula ukusebenza
Iziphumo zophando zamva nje zibonisa iipropati ezintle ze-alloy ye-Al-Si-Mg-Mn
Kwinkqubela phambili yophuhliso lweshishini leemoto, ukukhanyisa kube yindlela ebalulekileyo yokuphucula ukusebenza kakuhle kwamandla kunye nokusebenza kakuhle. Njengesixhobo esikhaphukhaphu nesinamandla aphezulu, i-aluminium alloy isetyenziswa ngakumbi kwimveliso yeemoto. Kutshanje, uphando kwi-alloy entsha ye-Al-Si-Mg-Mn enamandla aphezulu lubonelela ngembono entsha malunga nokusetyenziswa kwe-alloys ze-aluminium kwi-alloy yezithuthi.
Iimpawu zokuphumelela ze-alloy entsha ye-Al-Si-Mg-Mn
Ngokophando lwamva nje, amandla okutsalwa kwe-alloy entsha ye-Al-Si-Mg-Mn emva kokuphoswa ngodayi (njengoko iphoswe) anokufikelela kwi-230 ukuya kwi-310 MPa, amandla okuvelisa yi-200 ukuya kwi-240 MPa, kwaye ubude bumalunga ne-0.5%. Ukufezekisa oku kusebenza kunenzuzo ekwakhiweni kwesohlwayo. iIsigaba se-AlFeMnSi kunye nesakhiwo se-eutectic esinamanqanaba amaninzi kwi-alloy. Nangona kunjalo, ukwandiswa kwe-alloy kuphantsi, ikakhulu ngenxa yempembelelo ethe ngqo yee-pores ezinkulu kunye nezigaba zesibini ezirhabaxa.
Ukusetyenziswa kwetekhnoloji yokusika iidayi kunye nophuhliso lwee-alloys ze-aluminium
Njengenkqubo yokwenza izinto ezikufutshane ne-net, i-die-casting isetyenziswa kakhulu ekuveliseni iimoto, unxibelelwano, oomatshini bobunjineli kunye nezinye iindawo ngenxa yokusebenza kwayo okuphezulu kwemveliso, ukuchaneka kwemveliso okuphezulu kunye nokusebenza kakuhle. Kwiminyaka elishumi edlulileyo, iindawo ezininzi zeemoto ezenziwe ngentsimbi ekuqaleni zithathelwe indawo ziindawo ze-aluminium alloy die-casting, ezingagcini nje ngokunciphisa ubunzima besithuthi, kodwa zikwafezekisa iinjongo zokonga amandla kunye nokunciphisa ukukhutshwa komoya.
Ukuqinisa indlela yokusebenza kunye nokuphucula ukusebenza kwee-alloys ze-aluminium
Ukongeza izinto ezifana neMg, Cu, Mn okanye Zn kwii-aluminium alloys ukwenza iikhompawundi eziphakathi ezifana neAlMgZn, AlMn okanye Al2Cu kunokuphucula ngempumelelo amandla e-alloy. Isiphumo sokuqina kwezi alloys sibangelwa sisisombululo esiqinileyo kunye nokuqina kwemvula. Uphando lubonisa ukuba ngokongeza isixa esifanelekileyo seMn, akupheleli nje ekuncitshisweni kwesikhunta esinamathelayo, kodwa nemo ye- bIsigaba se-Fe sinokutshintshwa, nto leyo ephucula ngakumbi ukusebenza kwe-alloy.
Uphando malunga nolwakhiwo kunye neempawu zee-alloys ezintsha ze-aluminium
Abaphandi bayila ii-alloy ze-Al-Si-Mg-Mn ezinee-eutectic integral fractions ezahlukeneyo ngokusebenzisa izibalo ze-JMatPro phase diagram simulation. Ngokujonga i-microstructure kunye nohlalutyo lwe-fracture morphology, kwatyhilwa ukuvela kwesakhiwo kunye neempawu zokusebenza kwe-alloy. Uphando lufumanise ukuba izakhiwo ze-eutectic ezi-ultrafine zinokuphucula kakhulu amandla kunye ne-plasticity yee-alloys, zibonelela ngendlela entsha yokuphucula ukusebenza kwee-alloys ze-aluminium.
