Abstract

THE ELEVATED TEMPERATURE DEFORMATION OF G115 STEEL AND THE ASSOCIATED DEFORMATION MECHANISM

Highlights

  • The energy demand in the recent years is growing fast

  • Many researches have been applied in the last decades to test the mechanical properties of those metals that are exposed to high temperature

  • The present work is to investigate the effect of normalizing temperature of 9Cr-3W-3Co steel where in the last few years attentions have been paid on G115

Summary

INTRODUCTION

The energy demand in the recent years is growing fast. it is important to reduce the greenhouse emissions [1,2,3]. The present work is to investigate the effect of normalizing temperature of 9Cr-3W-3Co steel where in the last few years attentions have been paid on G115. This new sort of steel with excellent properties is expected to be used in Generation-IV reactor type for up to 750°C. As Generation-IV reactor has already been designed to work at a very high temperature (550 to 700°C), many investigations have been studying to find the most candidate material that can be afforded under a high temperature circumstances. The intention of this work is to investigate the mechanical characteristics and the elevated temperature deformation mechanism of G115 which is a candidate structural material of the Generation Nuclear Plants, NGNP
