Igiciro cyinshi Fe-b alloy agace FeB 95: 5wt Gukora cyane-Entropy Alloys (HEA) Gukora

Boron ifite uburemere bwa atome bwa 10.81. Imiterere ya elegitoronike ni 1s2s2p. Ubucucike bwa boron ya kristalline ni 2,31g / cm (20 ° C), naho ubucucike bwa bor amorphous ni 2,30g / cm (20 ° C). Gushonga ingingo 2079 ℃, ingingo itetse 3660 ℃. Igishushanyo cyicyiciro cya equilibrium ya sisitemu ya boron-fer yerekana ishusho ya 1. Muri sisitemu ya boroferric, hari eutectic point igera kuri 3.8% ya boron, naho ubushyuhe bwa eutectic ni 1149 ℃. Icyuma na boron bigize ibice bibiri hagati, Fe2B na FeB, nabyo bihagaze neza cyane kubushyuhe bwinshi. FeB ifite ubwoko bubiri bwa kirisiti: ubushyuhe bwo hejuru n'ubushyuhe buke. Inganda zikora inganda za boride (10% ~ 20% B) gushonga ubushyuhe bwa 1400 ~ 1550 ℃, ubucucike bwa 5.8 ~ 6.5g / cm

Umubare wa boron (0.001%) urashobora gukuba kabiri gukomera kwicyuma. Kwiyongeraho 0.003% B mubyuma bidafite ingese birashobora kunoza imikorere. Boron ifite imiterere yo gukuramo neutron, ishobora kubangamira cyangwa guhagarika urunigi rwerekana uranium-grafite ya kirimbuzi. Kubwibyo, ibyuma bifite boron nyinshi (> 1% B) bikoreshwa mubikorwa byingufu za atome. Boron mu byuma irashobora kugira ingaruka ku gushushanya, bityo bikongerera ubujyakuzimu umunwa. Iyo ingano ya boron yongewe irenze 0.01%, ingaruka zo guhagarika karbide iragaragara, bityo kurwanya kwangirika kwicyuma bikozwe neza. Kuzunguruka ibyuma, ibirimo boron 0.02% ~ 0.1%, birashobora kunoza ubukana bwubuso no kunoza umweru. Ongeraho Borda 0.001% ~ 0.005% mubyuma byoroshye byoroshye bifasha gukora wino ya spheroidal. Mugihe kimwe, irashobora kandi kongera ibice bya grafite no kunoza ikwirakwizwa ryayo. Ingaruka zifasha kuvura annealing. [2]

Icyuma, icyuma cya cobalt hamwe nifu ya nikel ikoreshwa mugutera (gusudira) irimo 0.5% ~ 4.0% boron. Amorphous fe-silicon-boron ivanze irimo boron, nka Feg2SisB3, irashobora gusimbuza ibyuma bya silikoni yerekanwe kugirango ikore transformateur izigama ingufu hamwe nibindi bikoresho bitakaza fer nkeya nubunini buke. Ndfeb magnesi zihoraho nka Nd2Fe14B na Nd15Fe77B8 zifite ibyiza byo kwihagararaho cyane, guhatira cyane hamwe ningufu zikoresha ingufu za magneti, nibikoresho byiza byo gukora ibice bya magneti bihoraho.
