All rights reserved.Nickel-based superalloys are group of alloys dedicated for energy saving at high temperature applications. Oxidation has been considered as the most significant degradation mode of the alloy when they are used at high temperatures. Aluminum and chromium have been widely involved in the alloys to provide protective oxides of Al2O3 and Cr2O3 as they grow relatively slow. However, spallation of the protective scales might occur when the components experience thermal cyclic. Increasing the oxidation resistance of Ni-based alloys has been done by doping of yttrium and hafnium. However, investigations of the effect of germanium and zirconium on the oxidation behaviour of nickel-based alloys are quite few and the mechanisms have not been well explained. This study investigated the cyclic oxidation behaviour of Ge and Zr additions on Ni-9.6Cr-5.6Al-2.4Ti alloy at 900, 1000 and 1100°C. It was found that while Zr improved the cyclic oxidation resistance of the alloy it gave higher oxidation rates. Meanwhile, Ge addition improved the oxidation resistance of the alloys by decreasing the oxidation rate as well as improving the spalling resistance.[/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][/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]Cyclic oxidation,Effect of Ge and Zr,High temperature oxidation,Nickel-based superalloys[/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][/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=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
