Mtengo wapamwamba wa Fe-b aloyi tinthu FeB 95:5wt High-Entropy Alloys(HEA) Kupanga

Boron ali ndi kulemera kwa atomiki 10.81. Kapangidwe kamagetsi ndi 1s2s2p. Kachulukidwe wa boroni wa crystalline ndi 2.31g/cm(20°C), pomwe kachulukidwe ka boron amorphous ndi 2.30g/cm(20°C). Malo osungunuka 2079 ℃, malo otentha 3660 ℃. Chithunzi cha gawo lofanana la boron-iron binary binary system ikuwonetsedwa mu Chithunzi 1. Mu dongosolo la boroferric, pali eutectic point pafupifupi 3.8% boron content, ndipo kutentha kwa eutectic ndi 1149 ℃. Iron ndi boron zimapanga mankhwala awiri apakatikati, Fe2B ndi FeB, omwenso amakhala okhazikika kwambiri pakutentha kwambiri. FeB ili ndi mitundu iwiri ya kristalo: kutentha kwakukulu ndi kutentha kochepa. Industrial kupanga chitsulo boride (10% ~ 20% B) kusungunuka kutentha osiyanasiyana 1400 ~ 1550 ℃, kachulukidwe wa 5.8 ~ 6.5g/cm

Kuchuluka kwa boron (0.001%) kumatha kuwirikiza kawiri kuuma kwachitsulo. Kuwonjezera pafupifupi 0.003% B ku chitsulo chosapanga dzimbiri kungathandize kusintha kwake. Boron ili ndi mphamvu yoyamwa manyutroni, omwe amatha kulepheretsa kapena kuyimitsa machitidwe anyukiliya a uranium-graphite. Chifukwa chake, chitsulo chokhala ndi boron wambiri (> 1% B) chimagwiritsidwa ntchito pamakampani opanga mphamvu za atomiki. Boron mu iron iron imatha kukhudza graphitization, motero kukulitsa kuya kwa mkamwa. Pamene kuchuluka kwa boron kuwonjezeredwa kupitirira 0.01%, zotsatira za kukhazikika kwa carbide ndizodziwikiratu, kotero kuti kukana kwachitsulo chachitsulo kumakhala bwino. Kugubuduza chitsulo, boron zili 0.02% ~ 0.1%, kumatha kulimbitsa kuuma kwapamwamba ndikuwongolera kulimba koyera. Kuonjezera Borda 0.001% ~ 0.005% ku chitsulo chosungunula chosungunuka kumathandizira kupanga inki ya spheroidal. Panthawi imodzimodziyo, imatha kuonjezera tinthu tating'ono ta graphite ndikuwongolera kugawa kwake. Izi zimathandiza kuti annealing mankhwala. [2]

Pansi pachitsulo, m'munsi mwa cobalt ndi ufa wa faifi tambala omwe amagwiritsidwa ntchito popopera (kuwotcherera) ali ndi boron 0.5% ~ 4.0%. Ma amorphous fe-silicon-boron alloys okhala ndi boron, monga Feg2SisB3, amatha kulowa m'malo mwachitsulo cha silicon kuti apange ma transfoma opulumutsa mphamvu ndi zida zina zomwe zimakhala ndi chitsulo chochepa komanso voliyumu yaying'ono. Ndfeb maginito okhazikika monga Nd2Fe14B ndi Nd15Fe77B8 ndi ubwino remanence mkulu, coercivity mkulu ndi mkulu maginito mphamvu mankhwala, amene ndi zipangizo zabwino kupanga mbali okhazikika maginito.
