Металлографические исследования отрезков труб, вырезанных из печи риформинга на Одесском припортовом заводе

Abstract

The results of metallographic investigations of the destruction of welding, pipe joints of dissimilar materials alloyed thermostable steel A335GrP11and heat-resistant alloy Manaurite XM. It is shown that the development of the ICC through the fusion appears as a consequence of the allocation of carbides along grain boundaries. On the inside of the pipe formed carbon-free layer.
