Gutakaza imizigo mugihe hatabayeho gucika mubisanzwe byerekana kuruhuka cyangwa 'kunyerera.' Mu gihe cyo kunanirwa mu kirere cyo mu kirere, amasoko 17-7PH yatakaje 15 ku ijana bya preload nyuma yamasaha 500 kuri 300 C. Isesengura rirambuye ry’ibyuma ryerekanye ko mu gihe 300 C iri mu ntera 'yagereranijwe', guhuza imbaraga nyinshi (70 ku ijana by’umusaruro) hamwe n’ubushyuhe byihutishije kugenda muri disikuru ya martensitike. Igisubizo kwari uguhindukira kuri Inconel X-750, ifite imbaraga zo guhangana cyane. Ikindi gishoboka ni 'kwambara' aho uhurira (crests); niba igikonjo cyashize kuri 0,05 mm gusa mugihe cyizuba hamwe nigipimo gito cyimpeshyi, kugabanuka kwumutwaro birashobora kuba byinshi kubera $ P = k \ cdot Δx $ umubano.
