Babban aiki Fe-b alloy barbashi Feb 95: 5wt High-Entropy Alloys(HEA) Manufacturing

Boron yana da nauyin atomic na 10.81. Tsarin lantarki shine 1s2s2p. Girman boron crystalline shine 2.31g/cm (20 ° C), yayin da yawan boron amorphous shine 2.30g/cm (20 ° C). Matsayin narkewa 2079 ℃, wurin tafasa 3660 ℃. An nuna ma'auni na ma'auni na tsarin binaryar boron-iron a cikin hoto na 1. A cikin tsarin boron, akwai alamar eutectic a kusan 3.8% abun ciki na boron, kuma zafin eutectic shine 1149 ℃. Iron da boron suna samar da tsaka-tsakin mahadi guda biyu, Fe2B da FeB, waɗanda suma suna da ƙarfi sosai a yanayin zafi. FeB yana da nau'ikan crystal guda biyu: babban zafin jiki da ƙananan zafin jiki. Masana'antu samar da baƙin ƙarfe boride (10% ~ 20% B) narkewa zafin jiki kewayon 1400 ~ 1550 ℃, da yawa na 5.8 ~ 6.5g / cm

Matsakaicin adadin boron (0.001%) na iya ninka ƙarfin ƙarfin ƙarfe. Bugu da kari na kusan 0.003% B zuwa bakin karfe na iya inganta iya aiki. Boron yana da kaddarorin ɗaukar neutrons, wanda zai iya hana ko dakatar da sarkar halayen uranium-graphite na nukiliya. Don haka, ana amfani da ƙarfe mai yawan boron (> 1% B) a cikin masana'antar makamashin atomic. Boron a cikin simintin ƙarfe na iya rinjayar graphitization, don haka ƙara zurfin bakin. Lokacin da adadin boron da aka ƙara ya wuce 0.01%, tasirin ƙarfafa carbide yana bayyana a fili, don haka an inganta juriya na simintin ƙarfe. Iron mirgina, boron abun ciki 0.02% ~ 0.1%, iya inganta surface taurin da inganta farin solidification. Ƙara Borda 0.001% ~ 0.005% zuwa simintin simintin gyare-gyare yana taimakawa wajen samar da tawada spheroidal. A lokaci guda kuma, yana iya ƙara ɓangarorin graphite kuma inganta rarraba ta. Wannan tasirin yana da tasiri ga maganin annealing. [2]

Tushen ƙarfe, cobalt base da nickel base foda da ake amfani da su don fesa (welding) sun ƙunshi 0.5% ~ 4.0% boron. Amorphous fe-silicon-boron alloys dauke da boron, kamar Feg2SisB3, na iya maye gurbin daidaitacce silicon karfe don yin masu canza wuta da sauran na'urori masu ƙarancin ƙarfe da ƙananan ƙara. Ndfeb m maganadiso kamar Nd2Fe14B da Nd15Fe77B8 da abũbuwan amfãni daga high remanence, high coercivity da high Magnetic makamashi samfurin, waxanda suke da manufa kayan don kerarre m maganadisu sassa.
