Abstract
ABSTRACT The effects of the chemical composition and heat treatment on the creep properties of Grade 91 steel base metal and welded joint were investigated by conducting creep tests on materials whose Al, Cr, and Ni contents were systematically varied or the normalising and tempering temperatures were varied. The effect of the chemical composition on the creep strength was similar for the base metal and the welded joint. That is, the creep strength decreased with increasing Al content, whereas the Ni content had little effect on the creep strength. Regarding the effect of heat treatment, the creep strength increased with increasing normalising temperature and decreasing tempering temperature for the base metal and the welded joint. The comparison of the test results of the welded joints with those of the base metals revealed a positive correlation between the creep strength of the base metals and that of the welded joints.
期刊介绍：
Materials at High Temperatures welcomes contributions relating to high temperature applications in the energy generation, aerospace, chemical and process industries. The effects of high temperatures and extreme environments on the corrosion and oxidation, fatigue, creep, strength and wear of metallic alloys, ceramics, intermetallics, and refractory and composite materials relative to these industries are covered.
Papers on the modelling of behaviour and life prediction are also welcome, provided these are validated by experimental data and explicitly linked to actual or potential applications. Contributions addressing the needs of designers and engineers (e.g. standards and codes of practice) relative to the areas of interest of this journal also fall within the scope. The term ''high temperatures'' refers to the subsequent temperatures of application and not, for example, to those of processing itself.
Materials at High Temperatures publishes regular thematic issues on topics of current interest. Proposals for issues are welcomed; please contact one of the Editors with details.
