I-Fe-Cr-Al yokushisisa ngogesi iyingxenye evame ukusetshenziswa ezintweni zokushisisa nezinto zikagesi, kanti i-Fe-Cr-Al kagesi yokushisisa intambo ingenye yezinto ezijwayelekile. Ezisetshenziswa ezingokoqobo, ukuqonda ubudlelwano phakathi kokumelana kwezintambo zokushisisa zikagesi nezinga lokushisa kubalulekile ekuklameni nasekulawuleni okokusebenza kokushisisa. Lesi sihloko sizohlola ubudlelwano phakathi kokumelana nezinga lokushisa kwezintambo zokushisa zikagesi ze-Fe-Cr-Al, futhi sithole ukuqonda okujulile kwezimiso zazo nezici ezinomthelela.
Okokuqala, ake siqonde imiqondo eyisisekelo yokumelana nezinga lokushisa. Ukumelana kusho isithiyo okuhlangatshezwana naso lapho i-current idlula entweni, futhi ubukhulu bayo buncike ezintweni ezifana nempahla, umumo, nosayizi wento. Futhi izinga lokushisa liyisilinganiso sezinga lokunyakaza okushisayo kwamangqamuzana nama-athomu ngaphakathi kwento, ngokuvamile elinganiswa ngamadigri Celsius noma Kelvin. Ezintanjeni zokushisa zikagesi, kunobudlelwane obuseduze phakathi kokumelana nokushisa.
Ubudlelwano phakathi kokumelana kwezintambo zokushisisa zikagesi ze-Fe-Cr-Al nezinga lokushisa bungachazwa ngomthetho wemvelo olula, okuyi-coefficient yezinga lokushisa. I-coefficient yezinga lokushisa ibhekisela ekushintshanisweni kokumelana kwezinto nezinga lokushisa. Ngokuvamile, njengoba izinga lokushisa likhuphuka, ukumelana nakho kuyanda. Lokhu kungenxa yokuthi ukwanda kwezinga lokushisa kungathuthukisa ukunyakaza okushisayo kwama-athomu nama-molecule ngaphakathi kwento, kubangele ukungqubuzana okwengeziwe nezithiyo ekuhambeni kwama-electron kumpahla, okuholela ekwandeni kokumelana.
Nokho, ubudlelwano phakathi kokumelana kwezintambo zokushisa ze-iron chromium aluminium nezinga lokushisa akubona ubudlelwano obulula bomugqa. Kuthonywa yizici ezihlukahlukene, phakathi kwazo okubaluleke kakhulu yi-coefficient yokushisa kanye nezici zezinto ezibonakalayo. Intambo yokushisisa kagesi ye-Fe-Cr-Al ine-coefficient ephansi yezinga lokushisa, okusho ukuthi ukumelana kwayo kushintsha kancane phakathi kwebanga elithile lokushintsha kwezinga lokushisa. Lokhu kwenza intambo yokushisisa kagesi ye-Fe-Cr-Al ibe isici sokushisisa esizinzile nesithembekile.
Ngaphezu kwalokho, ubudlelwano phakathi kokumelana nezinga lokushisa kwezintambo zokushisa ze-iron chromium aluminium nakho kuthonywa usayizi nokuma kwezintambo zokufudumeza.

Imvamisa, ukumelana kuhambisana nobude bentambo futhi kuhambisana ngokuphambene nendawo ye-cross-sectional. Ngakho-ke, izintambo zokushisa ezinde zinokuphikiswa okuphakeme, kuyilapho izintambo zokushisa eziqinile zinokuphikiswa okuphansi. Lokhu kungenxa yokuthi izintambo zokushisa ezinde zandisa indlela yokumelana, kuyilapho izintambo zokushisa eziqinile zinikeza isiteshi sokugeleza esibanzi.
Ezisetshenziswa ezingokoqobo, ukuqonda ubudlelwano phakathi kokumelana nezinga lokushisa kwezintambo zokushisa zikagesi ze-Fe-Cr-Al kubalulekile ekulawuleni okuphusile kanye nokulungiswa kwezinto zokushisisa. Ngokulinganisa ukumelana kwentambo yokushisa kagesi kanye nezinga lokushisa elizungezile, singakwazi ukulinganisa izinga lokushisa lapho ucingo lokushisa kagesi lutholakala khona. Lokhu kungasisiza ukuthi silawule kangcono izinga lokushisa lemishini yokushisa futhi siqinisekise ukusebenza kwayo okuvamile nokusetshenziswa okuphephile.
Kafushane, kunobudlelwano obuthile phakathi kokumelana nezintambo zokushisa ze-iron chromium aluminium nezinga lokushisa. Njengoba izinga lokushisa likhuphuka, ukumelana nakho kuyanda, kodwa ushintsho luncane phakathi kwebanga elincane. I-coefficient yezinga lokushisa, izakhiwo zezinto ezibonakalayo, nosayizi nokuma kwentambo yokushisisa konke kuthinta lobu budlelwano. Ukuqonda lobu budlelwano kungasisiza ukuthi siklame kangcono futhi silawule imishini yokushisisa, sithuthukise ukusebenza kahle kwayo nokwethembeka.
