In this paper first a generally valid model is derived from the two fundamental equations of
Gibbs for temperature and composition dependences of all types of interfacial energies. This …

Designing a material with multiple desired properties is a great challenge, especially in a
complex material system. Here, we propose a material design strategy to simultaneously …

A γ′ strengthened Co–Ti–Cr superalloy is presented with a mass density∼ 14% below that
of typical Co–Al–W-based alloys. The lattice misfit is sufficiently low to form coherent …

The present paper reports the development of W-, Mo-, and V-free and Ni-and Cr-containing
Co–Al–Ta-based superalloys. In particular, the presence of a metastable L1 2-γ′ phase is …

The presented paper concerned a comparison of microstructural characters and mechanical
performances between the cobalt based alloy (Co-based) coatings of the same chemical …

Coherent precipitation of cuboidal γ'-Co 3 (Al, W) nanoparticles in face-centered-cubic
(FCC)-γ matrix is of great significance for improving high-temperature mechanical properties …

A set of advanced single crystalline γ′ strengthened Co-base superalloys with at least nine
alloying elements (Co, Ni, Al, W, Ti, Ta, Cr, Si, Hf, Re) has been developed and investigated …

A method was developed to suppress the crack formation during laser powder bed fusion
(LPBF) of molybdenum (Mo). The method uses a nitrogen (N 2) atmosphere to fabricate …

The paper explores the influence of Ti addition to the Ta stabilized γ/γ′ two-phase Co-
based superalloys having the compositions of Co-30Ni-10Al-5Mo-2Ta-xTi (x= 0, 1, 2 and 4 …

In this study, a Co-30Ni-10Al-6Ta-10Cr alloy was designed based on CALPHAD
(Calculation of Phase Diagrams) method targeting high γ′ phase fraction and solvus, and …
