A novel experimental method of estimating tracer and intrinsic diffusion coefficients from multicomponent diffusion profiles
Neelamegan Esakkiraja, Anuj Dash, Avik Mondal +2
A few decades earlier, Kirkaldy and Lane proposed an indirect method of estimating the tracer and intrinsic diffusion coefficients in a ternary system (without showing experimental…
Composition dependence of tracer diffusion coefficients in Fe-Ga alloys: a case study by a tracer-interdiffusion couple method
G. M. Muralikrishna, B. Tas, N. Esakkiraja +7
The problem of estimation of the tracer diffusion coefficients is solved by utilizing a novel tracer-interdiffusion couple technique even in the absence suitable radioisotope of on…
Solving the issues of multicomponent diffusion in an equiatomic NiCoFeCr medium entropy alloy
Anuj Dash, Neelamegan Esakkiraja, Aloke Paul
Estimating the diffusion coefficients experimentally in a four-component inhomogeneous alloy following the conventional diffusion couple method by intersecting three couples at the…
A mystery of "sluggish diffusion" in high-entropy alloys: the truth or a myth?
Sergiy V. Divinski, Alexander Pokoev, Neelamegan Esakkiraja +1
High entropy alloys (HEAs) are considered as a novel class of materials with a large number of components available in nearly equatomic proportions. One of the characteristic prope…
A novel concept of pseudo ternary diffusion couple for the estimation of diffusion coefficients in multicomponent systems
Neelamegan Esakkiraja, Aloke Paul
A pseudo ternary diffusion couple technique in a multicomponent system by simplifying the mathematical complications of Onsager formalism is proposed for the estimation of composit…
