Brittleness Of Alloys For Water Pipes Estimated By Methods Of Acoustic Emission And Microindentation

This paper deals with the investigation of the influence of various external factors (longtime exploitation; friction; corrosion) on Fe alloys water pipes mechanical properties studied by the microindentation method along with acoustic emission one. It has been shown that long-time exploitation (as...

description This paper deals with the investigation of the influence of various external factors (longtime exploitation; friction; corrosion) on Fe alloys water pipes mechanical properties studied by the microindentation method along with acoustic emission one. It has been shown that long-time exploitation (as well as aging) don't practically change such characteristics as hardness and brittleness. The fine polishing has a very small influence, while coarse grinding slightly increases these parameters. The most effect of brittleness increase has been observed for the water pipes subjected to corrosion.
