Abstract

Surface potential of aluminum alloy AA 3204 undergoing an irregular (serrated) plastic flow was monitored in 0.1 M NaCl solution under various strain rates from 1.0x10-4/s to 2.0x10-5/s at RT (20 oC). Large potential bursts at the stress drop periods of the irregular flow were revealed. Number and frequency of the stress drops along the plastic region matched with that of the bursts precisely, and average burst magnitude was found to be related with that of the stress drops. The observations affirmed an in-situ utility of the electrochemical method for monitoring deformation and damage evolution in aqueous environments for materials susceptible to irregular flow.

Özet

Düzensiz (kesikli) plastik deformasyona uğrayan AA 3204 aluminyum alaşımının yüzey potansiyeli oda sıcaklığındaki (20 oC) 0.1 M NaCl çözeltisi içinde, 1.0x10-4/s ve 2.0x10-5/s arasında değişen çeşitli germe hızları altında izlendi. Düzensiz deformasyondaki stres düşüşleri sırasında büyük potansiyel taşmaları ortaya çıktı. Plastik bölge boyunca stres düşüş sayısı ve sıklığı potansiyel taşmalarınınki ile tam olarak uyuştu. Gözlemler elektrokimyasal yöntemin düzensiz deformasyona yatkın malzemelerin sulu ortamlardaki deformasyon ve zararının izlenmesinde kullanışlı olduğunu ortaya koydu.
