Microstructural characterization of modified 25Cr–35Ni centrifugally cast steel furnace tubes
TL;DR: In this paper, the HP steels modified with Nb and Nb-plus-Ti, produced in the form of centrifugally cast tubes, were characterized by means of light optical microscopy, scanning electron microscopy (SEM) with secondary and backscattered electron imaging, and transmission electron microscope with energy-dispersive spectroscopy (EDS) and selected area diffraction.
Journal ArticleDOI
Niobium additions in HP heat-resistant cast stainless steels
TL;DR: In this paper, the microstructures of HP-type heat-resistant cast steels, having niobium additions up to 2 wt., were examined in the as-cast condition and after artificial aging at 700, 900, and 1100°C.
Journal ArticleDOI
Role of Nb in modifying the microstructure of heat-resistant cast HP steel
TL;DR: In this paper, the role of Nb in modifying the microstructure of HP steel in the as-cast and artificially aged conditions, for a series of alloys utilizing different levels of nb.
Journal ArticleDOI
Effects of Si content on the microstructure of modified-HP austenitic steels
Raul Alejandro Pedro Ibañez,Gloria Dulce de Almeida Soares,Luiz Henrique de Almeida,Iain Le May +3 more
TL;DR: The microstructures of two centrifugally cast modified-HP steels with 1.97 wt.% Nb and two different Si contents, 1.84 and 2.62 wt., were investigated using light and electron microscopy and x-ray diffraction as mentioned in this paper.
Journal ArticleDOI
Phase characterization in two centrifugally cast HK stainless steel tubes
TL;DR: In this paper, the precipitates present in two HK steels after exposure at 890°C for some 60,000 h have been identified, and the formation of the intermetallic is related to instability of the NbC with long-time exposure.
