Bu çalışmada, HY 80 çeliğinin, HCI, H2 S0 4 ve NaOH çözeltileri gibi çeşitli ortamlardaki mekanik davranışı deneysel olarak incelenmiştir. Plaka numuneleri, çekme numuneleri ve V çentikli numuneler, HCl, H2 S0 4 and NaOH çözeltilerine daldırılmıştır. HY 80 çeliğinin yüzeyinde korozif ortamın agresifliğini belirlemek için her bir H2 S04 , NaOH ve HCl çözeltileri için daldırılan HY 80 yassı levha numunelerinin kütle kayıpları 1 hafta, 2 hafta ve 4 hafta sonra ölçülmüştür. Ayrıca, çekme numuneleri ve V çentikli numuneler, korozif ortamın HY 80 çeliklerinin kırılma tokluğu ve akma davranışı üzerindeki etkisini incelemek için 1, 2 ve 4 hafta boyunca daldırılmıştır. Sonuçlar, HY 80 çeliğinin akma dayanımı ve nihai çekme dayanımı, HCl ve H2 S04 'ün asidik çözeltilerine daldırıldıktan sonra azaldığını göstermesine rağmen, NaOH çözeltisine daldırıldıktan sonra değişkenlik göstermemiştir. Ayrıca asidik ortamın etkisi HY 80 çeliğinin kırılma tokluğunu düşürmüştür.

An Experimental Investigation of Mechanical Behavior of HY 80 Steel in Corrosive Mediums

Öz

In this study, mechanical behavior of HY 80 steel in various mediums such as solutions of HCl, H2 S0 4 and NaOH has been investigated experimentally. The plate specimens, tensile specimens and V-notched specimens are immersed in solutions of HCl, H2 S0 4 and NaOH. Mass losses of immersed HY 80 flat plate specimens are measured after 1 week, 2 weeks and 4 weeks for each H2 S04 , NaOH and HCl solutions to determine the aggressivity of the corrosive medium to surface of HY 80 steel. Also, tensile specimens and V-notched specimens are immersed for 1, 2 and 4 weeks to study on the effect of corrosive medium on fracture toughness and yielding behavior of HY 80 steels. The results show that however, yielding strength and ultimate tensile strength of HY 80 steel have reduced after immersed in acidic solutions of HCl and H2 S04 , are stable after immersed in solution of NaOH. Furthermore, effect of acidic medium lower the fracture toughness of HY 80 steel.
