Zogulitsa NKHANI
GH648 ndi Ni-Cr yochokera ku mvula yowumitsa kutentha kwa aloyi ndi kutentha kwanthawi yayitali kosakwana 900 ° C komanso kutentha kwakanthawi kochepa mpaka 1100 ° C. Aloyiyi imadziwika ndi kuwonjezera pafupifupi 32% ya ω(Cr), yomwe imapangitsa kuti ikhale yolimba kwambiri yolimbana ndi dzimbiri. Aloyiyi imadziwika ndi kuwonjezera pafupifupi ω (Cr) 32%, kotero kuti imakhala ndi kukana kwamphamvu kwamafuta. Pa nthawi yomweyo, aloyi ali ndi mphamvu sing'anga ndi kutopa wabwino ndi kukwawa kukana, zabwino ozizira ntchito katundu ndi kuwotcherera katundu. Ndizoyenera kupanga zigawo zamapangidwe apamwamba kwambiri ndi kutentha kwa 900 ℃-1000 ℃ komanso kukana kwa dzimbiri. Mitundu yayikulu yomwe imaperekedwa ndi mbale, mizere, mipiringidzo, ma forging ndi mphete. Ntchito yonse ya alloy ndi yabwino kuposa GH3044 yapakhomo ndi GH3128. Chifukwa GH648 ili ndi mphamvu yokoka yaying'ono kuposa GH3044, alloy ili ndi mphamvu zapadera.
Kugwiritsa ntchito mankhwala
Aloyiyo yakhala ikugwiritsidwa ntchito popanga zida zachipinda choyaka moto ndi zida zina zotentha zamainjini apamwamba kwambiri, ndikupanga bwino batch ndikugwiritsa ntchito. Magiredi ofanana agwiritsidwa ntchito kwambiri m'mainjini akunja akunja.
