Effect Of DyMn Alloy-Powder Addition On Microstructure And Magnetic Properties Of NdFeB Sintered Magnets

Archives of Metallurgy and Materials, 2015
Micostructural change and corresponding effect on coercivity of a NdFeB sintered magnet mixed with small amount of DyMn powder was investigated. In the sintered magnet mixed with the DyMn alloy-powder Dy-rich shell was formed at outer layer of the main ...

Fractional order triple-phase-lag thermoelasticity in the context of two-temperature theory

Partial Differential Equations in Applied Mathematics, 2022
A new mathematical model is designed through reconstructing the triple-phase-lag model proposed by Roy Choudhuri, where the integer ordered derivatives concerning the time variable are replaced by the Caputo time-fractional derivative of order δ∈(0,1 ...
