Answer
Aerospace da petrochemical aikace-aikace suna buƙatar daidaitattun ƙimar bazara a ƙarƙashin yanayin zafi mai ƙarfi.
Iyakar Bakin Karfe 17-7 PH:
- Matsakaicin Yanayin Aiki: $650^\circ F$ ($343^\circ C$)
- Halayen Aiki: Ƙarfin ɗaukar nauyi mai girma, mai tsada, amma yana samun kwanciyar hankali mai tsanani (asara-asara) sama da $650 ^\circ F$ saboda raƙuman ƙaramin tsari na thermal.
Inconel X-750 (Nickel-Chromium Alloy) Iyaka:
- Matsakaicin Yanayin Aiki: $1300^\circ F$ ($704^\circ C$)
- Maganin zafi: Hazo ya taurare ta hanyar warware matsalar da taurin shekaru don inganta ƙarfin fashewa.
- Ayyuka: Yana da juriya na musamman ga oxidation da creep. A yanayin zafi tsakanin $650^\circ F$ da $1000^\circ F$, Inconel X-750 yana kula da modul ɗin sa na roba ($ E_t = E_0 \ cdot [1 - \ alpha \ Delta T] $) da ya fi daidai da daidaitattun ƙarfe, yana fuskantar ƙasa da 5% asarar nauyi akan tsawaita bayyanar hawan keke.
