Influence of stress concentrators on the temperature dependence of the liquid metal embrittlement of Armco iron
- Karpenko Physicomechanical Institute, L`viv (Ukraine)
We study temperature dependences of the effects of liquid indium and lead-bismuth eutectics on the ultimate strength and tensile elongation of Armco iron. Tests were performed on Armco iron cylindrical specimens with stress concentrators and with square cross section under active strain with a rate of 8.3 {center_dot} 10{sup {minus}4} s{sup {minus}1}. It was found that, under identical test conditions, the decrease in the ultimate strength of the specimens with concentrators caused by the effect of melts occurs in a broader temperature range than the embrittlement of specimens without concentrators. The effect of liquid metals also depends on the size of the grains in iron (26-110 {mu}m) but its character is different for specimens with and without concentrators.
