Ukusebenza kwezindleko eziphezulu Fe-b ingxubevange yezinhlayiyana FeB 95:5wt High-Entropy Alloys(HEA) Manufacturing

I-Boron inesisindo se-athomu esingu-10.81. Isakhiwo se-elekthronikhi yi-1s2s2p. Ukuminyana kwe-crystalline boron ngu-2.31g/cm(20 ° C), kuyilapho ukuminyana kwe-amorphous boron kungu-2.30g/cm(20 ° C). Iphoyinti lokuncibilika 2079 ℃, iphoyinti elibilayo 3660 ℃. Umdwebo wesigaba sokulingana wesistimu kanambambili ye-boron-iron uboniswa kuMfanekiso 1. Ohlelweni lwe-boroferric, kukhona iphoyinti le-eutectic cishe elingu-3.8% wokuqukethwe kwe-boron, futhi izinga lokushisa le-eutectic lingu-1149℃. I-ayoni ne-boron zakha izinhlanganisela ezimbili eziphakathi, i-Fe2B ne-FeB, nazo ezinzile ngokwedlulele emazingeni okushisa aphezulu. I-FeB inezinhlobo ezimbili zekristalu: izinga lokushisa eliphezulu nezinga lokushisa eliphansi. Ukukhiqizwa kwezimboni ze-iron boride (10%~20%B) izinga lokushisa elincibilikayo lika-1400~1550℃, ukuminyana kuka-5.8~6.5g/cm

Inani elincane le-boron (0.001%) lingaphinda kabili ukuqina kwensimbi. Ukwengezwa cishe ngo-0.003% B ensimbi engagqwali kungathuthukisa ukucutshungulwa kwayo. I-Boron inezici zokumunca ama-neutron, angavimbela noma amise ukusabela kweketango lokusabela kwe-uranium-graphite yenuzi. Ngakho-ke, insimbi ene-boron ephezulu (>1% B) isetshenziswa embonini yamandla e-athomu. I-Boron ku-cast iron ingathinta i-graphitization, ngaleyo ndlela ikhulise ukujula komlomo. Lapho inani le-boron elengeziwe lingaphezu kuka-0.01%, umphumela wokuzinzisa i-carbide uyabonakala, ngakho-ke ukumelana nokugqoka kwensimbi ensimbi kuyathuthukiswa. I-ayoni eginqikayo, okuqukethwe kwe-boron okungu-0.02%~0.1%, kungathuthukisa ukuqina kwendawo futhi kuthuthukise ukuqiniswa okumhlophe. Ukwengeza i-Borda 0.001%~0.005% ensimbini ethambile ethambile kulungele ukwenza uyinki oyindilinga. Ngesikhathi esifanayo, kungandisa futhi izinhlayiya ze-graphite futhi kuthuthukise ukusatshalaliswa kwayo. Lo mphumela uhambisana nokwelashwa kwe-annealing. [2]

Isisekelo sensimbi, i-cobalt base kanye ne-nickel base powder esetshenziselwa ukufafaza (welding) iqukethe i-boron engu-0.5%~4.0%. Ama-amorphous fe-silicon-boron alloys aqukethe i-boron, njenge-Feg2SisB3, angangena esikhundleni sensimbi ye-silicon eqondiswe ukwenza iziguquli zokonga amandla nezinye izisetshenziswa ezinokulahleka kwensimbi ephansi nevolumu encane. Ozibuthe be-Ndfeb abangapheli abanjengo-Nd2Fe14B kanye ne-Nd15Fe77B8 banezinzuzo zokuhlala kabusha okuphezulu, ukuphoqelelwa okuphakeme kanye nomkhiqizo wamandla kazibuthe ophezulu, okuyizinto ezifanele zokukhiqiza izingxenye zikazibuthe unomphela.
