Produced ceramic-lined steel pipe using the self-propagating high-temperature
synthesis (SHS) method has found uses in many applications. A SHScentrifugal
machine was designed to produce a ceramic-lined steel pipe from
ferric oxide and aluminum powder (thermite mixture) under high centrifugal
acceleration. The obtained products are expected to be Al2O3 ceramic in the
innermost layer and a Fe layer in a region between the outer steel pipes. In
the present work, specific regions of a pipe was particularly observed to
investigate the stuck (dead) spaces at the pipe head because of its importance
in further processes (joining, welding, etc.) which may affect the quality of the
next operations. In this article, the product’s composition, phase separation,
microhardness, and surface finish were studied on three zones of the pipe.
