Answer
Kuvura Cryogenic (gukonjesha $ -300 ^ {\ umuzenguruko} F $ ukoresheje azote yuzuye) rimwe na rimwe bikoreshwa kugirango habeho ihinduka ryuzuye rya austenite yagumishijwe muri martensite mu byuma bya karubone nyinshi. Austenite yagumanye ntigihinduka kandi irashobora guhinduka mugihe cyubushyuhe bwicyumba, bigatuma ubwiyongere buke buke. Kugirango impeta zisobanutse neza muri sisitemu yo hejuru ya optique cyangwa kugendagenda, iyi drift irashobora kuba ikibazo. Gutunganya Cryogenic itanga microstructure ihamye, ikagabanya ubukana kandi ikemeza ko diameter yubusa impeta $ D_s $ ikomeza guhora hejuru yubuzima bwigikoresho.
