Use of quasi-crystalline aluminum alloys in applications in refining and petrochemistry

Abstract

Materials that consist at least in part of aluminum quasi-crystals whose composition is represented by the general formula: AlaCubCocFEdCreMfIg, in which M represents one or more additional minor elements and I represents one or more alloy impurities and with, in terms of percentage of atoms, 0<b<30, 0<c<30, 0<d<20, 0<e<20, 0<f<10, 0<g<2, and a+b+c+d+e+f+g=100, are used in the manufacture of devices or device parts, for example, tubes, plates, or hoops, for building furnaces, reactors, or pipes, or for lining the inner walls of reactors, furnaces, or pipes inside of which conditions can prevail for coke formation, carburization, sulfurization, nitration, oxidation, or attack by halogenating agents when refining and petrochemical processes are implemented.
