Development of next generation tempered and ODS reduced activation ferritic/martensitic steels for fusion energy applications

Current developments in kinetic and thermodynamic stabilization of grains in nanostructured metals, alloys, and compounds are generalized and discussed in detail. As applied to the thermodynamic approach, attention has recently shifted from using the regular solution approximation to estimating thermodynamic properties of nanomaterials by considering both inner regions of nanograins and their grain boundaries. This situation is discussed and examples for alloys based on iron, copper, tungsten, and other elements are presented. Experimental information about behavior of nanomaterials subjected to radiation or oxidation is considered, along with recent experiments on abnormal grain growth.

Effect of zirconium addition on the microstructure and mechanical properties of ODS ferritic steels containing aluminum

ODS-304 austenitic steel (pre-alloyed austenitic steel powders +0.35 wt% Y 2 O 3 +0.5 wt% Ti) was fabricated by the process of mechanical alloying and hot isostatic pressing. The milled powders were characterized by XRD and SEM. New peaks of YO 1.401 appeared after milling of 5 h, which indicated that Y 2 O 3 decomposed and dissolved into the matrix during MA. A bimodal distribution of grains was found in the as-HIPed specimen by TEM. It was found that fine oxide particles enriched in Y–Ti–O were dispersed in the small grains, while there were almost no dispersoids inside the large grains. Plastic deformations, including forging and hot rolling, were subjected to the as-HIPed specimens. Tensile properties were measured at 23 and 700 °C. At 23 °C, the UTS and elongation of the as-HIPed specimen reached 940 MPa and 24.5% respectively. Specimens showed much higher ductility after plastic deformations while there was just slight decrease of tensile strength at the same time.
