Ukusebenza kwexabiso eliphezulu Fe-b ingxubevange yesuntswana FeB 95:5wt High-Entropy Alloys(HEA) Manufacturing

I-Boron inobunzima be-athomu ye-10.81. Ubume bombane yi-1s2s2p. Ubuninzi be-crystalline boron yi-2.31g/cm(20 ° C), ngelixa ukuxinana kwe-amorphous boron yi-2.30g/cm(20 ° C). Indawo yokunyibilika i-2079℃, indawo yokubila i-3660℃. Umzobo wesigaba sokulingana se-boron-iron binary system iboniswe kuMzobo 1. Kwinkqubo ye-boroferric, kukho indawo ye-eutectic malunga ne-3.8% yomxholo we-boron, kwaye ubushushu be-eutectic yi-1149℃. I-iron kunye ne-boron zenza iikhompawundi ezimbini eziphakathi, i-Fe2B kunye ne-FeB, nazo ezizinzileyo ngokugqithisileyo kumaqondo aphezulu. I-FeB ineentlobo ezimbini zekristale: ubushushu obuphezulu kunye nobushushu obuphantsi. Imveliso ye-iron boride ye-iron (10% ~ 20% B) iqondo lokushisa elinyibilikayo le-1400 ~ 1550℃, ubuninzi be-5.8 ~ 6.5g / cm

Umkhondo we-boron (0.001%) unokuphinda kabini ukuqina kwentsimbi. Ukongezwa malunga ne-0.003% B kwinsimbi engenasici kunokuphucula ukusebenza kwayo. I-Boron ineempawu zokufunxa i-neutron, enokuthi ithintele okanye imise ukusabela kwetsheyini lokusabeleka kwe-uranium-graphite yenyukliya. Ngoko ke, intsimbi enomxholo ophezulu we-boron (> 1% B) isetyenziswa kwishishini lamandla e-athomu. I-Boron kwi-iron cast inokuchaphazela i-graphitization, ngaloo ndlela ikhulise ubunzulu bomlomo. Xa inani le-boron elongeziweyo lingaphezulu kwe-0.01%, umphumo wokuzinzisa i-carbide uyabonakala, ngoko ke ukuxhatshazwa kwentsimbi kuphuculwe. I-iron rolling, umxholo we-boron 0.02% ~ 0.1%, unokuphucula ukuqina komphezulu kunye nokuphucula ukuqina okumhlophe. Ukongeza i-Borda 0.001% ~ 0.005% kwintsimbi etyhidiweyo etyhidiweyo ilungele ukwenza inki ye-spheroidal. Ngexesha elifanayo, inokunyusa kwakhona iinqununu zegraphite kunye nokuphucula ukusabalalisa kwayo. Esi siphumo siluncedo kunyango lwe-annealing. [2]

Isiseko sentsimbi, isiseko se-cobalt kunye ne-nickel base powder esetyenziselwa ukutshiza (i-welding) iqulethe i-0.5% ~ 4.0% ye-boron. I-amorphous fe-silicon-boron alloys equkethe i-boron, efana ne-Feg2SisB3, ingathatha indawo yensimbi ye-silicon ejoliswe kuyo ukwenza iziguquli zokulondoloza amandla kunye nezinye izixhobo ezinokulahlekelwa kwentsimbi ephantsi kunye nomthamo omncinci. Iimagnethi ezisisigxina ze-Ndfeb ezifana ne-Nd2Fe14B kunye ne-Nd15Fe77B8 zineenzuzo ze-remanence ephezulu, ukunyanzeliswa okuphezulu kunye nemveliso yamandla ombane aphezulu, ezizizixhobo ezifanelekileyo zokuvelisa iinxalenye zemagnethi ezisisigxina.
