| Outline of Final Research Achievements |
Oxidation-resistant grain refined W-alloy laminates, that combines the advantages of grain refined W-alloy and W-foil laminate, and furthermore, adds oxidation resistance through the addition of Cr, were developed. Although the developed grain refined W alloy showed oxidation resistance, it was found that the ductility could not be adjusted due to the high hardness caused by the addition of Cr. Therefore, it was determined that it would be difficult to achieve the research initial goal with the addition of Cr. On the other hand, the prospect of property improvement was obtained by reducing Cr and adjusting manufacturing conditions, and it also became clear that ductile W laminate could be realized using a material with high hardness and low ductility as a base material, so further research was conducted to determine the possibility of achieving the initial goal.
