In addition, density, porosity and hardness were also observed. Four compositions of ferritic steels as Fe-17Cr-3.5Al-Ti-Y (‘FP’), Fe-17Cr-3.5Al-Ti-Y-0.4Y2O3 (‘FY’), Fe-17Cr-3.5Al-Ti-Y-0.4ZrO2 (‘FZ’), and Fe-17Cr-3.5Al-Ti-Y-0.2Y2O3-0.2ZrO2 (‘FYZ’) were prepared by mechanical alloying and followed by sintering at 1000 °C. Microstructure characteristics were observed for different aspect, viz. elemental distribution, composition, and phase identification. Cyclic oxidation tests were carried out at 800 °C for 8 cycles. The results show that ZrO2 addition suppresses the formation of Y-Al-O clustering and promotes the formation of Y-Zr-O clustering and the enhancement of oxidation resistance of the alloy. However, in some condition it also has a deleterious effect on crack resistance. In contrast, the addition of Y2O3 decreases the oxidation resistance but increases the hardness.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Crack resistance,Cyclic oxidation tests,Cyclic-oxidation resistance,Deleterious effects,Elemental distribution,Microstructure characteristics,Phase identification,Spark plasma sintering method[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The financial support from Indonesian Institute of Science is kindly acknowledged (Kegiatan Unggulan LIPI).
