Abstract


The Mechanical alloying method, the sol-gel-spark plasma sintering method and the vacuum casting method are researched which are used to prepare nano-structured oxide dispersion strengthened (ODS) RAFM steels. Nano-structured ODS RAFM steels can be obtained by The Mechanical alloying methods and the sol-gel-spark plasma sintering methods. Micron-structured ODS RAFM steels can be obtained by vacuum casting method. The microstructure of the material manufactured by different methods are compared.

Keywords
