Answer
A-286 superalloy ne na tushen ƙarfe wanda aka ƙera don aikace-aikacen ƙarfi mai ƙarfi a yanayin zafi har zuwa $ 1300 ^ circ F $. Ba kamar carbon steels wanda ya rasa duk tsarin mutunci sama da $400 ^ \ cir F$, A-286 yana kula da ƙarfin yawan amfanin ƙasa da juriya na iskar shaka. A cikin injunan jet, ana amfani da maɓuɓɓugan raƙuman ruwa don kiyaye tashin hankali axial akan bearings ko hatimi. Maganin zafi ya ƙunshi maganin anneal wanda ya biyo baya taurin hazo a $1325^\circ F$. Sakamakon microstructure ya ƙunshi $Ni_3Ti$ hazo wanda ke toshe motsi. Lokacin zayyana da A-286, injiniyoyi dole ne su yi amfani da rage Modulus na Elasticity ($ E \ kusan 23 \ times 10^6$ PSI a $1000^\circ F $) a cikin kididdigar ƙimar su don tabbatar da an sami preload ɗin da ake buƙata a yanayin aiki.
