Role of oxidation and recrystallisation on very-high-cycle fatigue of columnar-grained DZ125
and single-crystal DD6 superalloys are investigated. With the temperature increase from 850 …

Internal nitridation of IN617 was investigated during creep rupture at 1000° C. The results
indicated that internal nitridation seriously deteriorated creep properties. Various nitrides …

Ferrosilicon alloys are widely used as a deoxidizer in steelmaking due to their strong oxygen
affinity and high deoxidizing ability. However, compared to other deoxidizers, relatively few …

A new class of polycrystalline gamma-prime strengthened superalloys with alloy
compositions of (wt%) Ni-20Co-13Cr-6Fe-4Al-3W-2Mo-(4-x) Nb-(x) Ti (x= 0, 1, 2) were …

To continue improving alloy performance in harsh service environments, the development of
alumina-forming nickel-based superalloys is essential. Current generations of these alloys …

Nickel-based superalloys have excellent properties at high temperatures, which makes them
appropriate for applications such as turbocharges and aeronautic gas turbines. MAR-M246 …

Considering the lower cost of Nb and its chemical similarity to Ta, this work investigated the
effect of complete replacement of Ta by Nb (in at.% basis) in MAR-M246 Ni-based …

Homogenization heat treatment is a key process to remove the micro-segregation and re-
dissolve the undesired phases for wrought superalloy. The oxidation behavior of the …

New Ni-base superalloys with higher temperature capability are required for future, more
efficient gas turbine engines. In designing such alloys, careful consideration is required of …

The effect of variations in Nb, Ta, and Ti concentrations in exchange for Al on the oxidation
resistance of a new polycrystalline Ni-based superalloy (C19) was studied in air at 800° C …
