Optimizing Annealing Temperature Control for Enhanced Magnetic Properties in Fe-Si-B Amorphous Flake Powder Cores
Autor: Hea-Ran Kim, Dongsup Lee, Sangsun Yang, Young-Tae Kwon, Jongryoul Kim, Yunseok Kim, Jae-Won Jeong
Publikováno v: Metals, Vol 13, Iss 12, p 2016 (2023)
In this study, we examined the optimal pre- and post-annealing conditions for soft magnetic composites (SMCs) using amorphous flake powders produced through ball milling of amorphous Fe-Si-B ribbons, leading to enhanced magnetic properties. The SMCs,

Improved Soft Magnetic Properties in FeNi@MgO Composites by Sol-Gel-Based Surface Coating and High-Temperature Heat Treatment
Autor: Jeong-Hyeon Park, Hea-Ran Kim, Jung-Woo Lee, Jae-Won Jeong
Publikováno v: Metals, Vol 13, Iss 8, p 1383 (2023)
In this study, we utilized MgO as an insulating buffer layer to enhance the thermal stability and soft magnetic properties of Fe-Ni soft magnetic composites (SMCs) and investigated the effect of high-temperature heat treatment on those soft magnetic

Enhanced Permeability of Fe-Based Amorphous Powder Cores Realized through Selective Incorporation of Carbonyl Iron Powders at Inter-Particle Voids
Autor: Hea-Ran Kim, Min-Sun Jang, Yeong-Gyun Nam, Yun-Seok Kim, Sang-Sun Yang, Yong-Jin Kim, Jae-Won Jeong
Publikováno v: Metals, Vol 11, Iss 8, p 1220 (2021)
In this study, we demonstrate a hybrid multimodal soft magnetic composite (SMC) comprising gas-atomized spherical amorphous powder (AP) and carbonyl-iron powder (CIP), and present its enhanced electromagnetic properties. CIP is selectively incorporat
