“…It is noteworthy to mention that upon thermal annealing, FINEMET-Ta and FINEMET-Hf generally exhibit better soft magnetic properties than FINEMET-TaC and FINEMET-HfC. These changes reveal magnetic softening of all FINEMET alloys upon thermal annealing, which agrees with previous works by Varga et al, Talaat et al, and Gam et al [37][38][39] The significantly lower P loss in all the thermal annealed FINEMET alloys also shows a great promise for high frequency switching applications where reduction in heat loss is beneficial. 2,[40][41][42][43] HTX005 was developed by McHenry et al and shown to have tunable magnetic anisotropy by strain annealing.…”

Amorphous and nanocrystalline soft magnetic alloys have garnered interests in academia and industry due to their potentials for applications, such as power transformers, electric motors, and sensors. To achieve good glass formability, thermal stability, and prevent grain overgrowth, elements such as B, Nb, Ta, and Hf are used in many soft magnetic systems. However, the high price of these precursors results in expensive soft magnetic alloys. Herein, we report on substituting Ta and Hf with TaC and HfC, respectively, to significantly reduce the cost of Fe-based FINEMET and Co-based HTX005 alloys. Soft magnetic properties of these alloys are studied. The effect of thermal annealing and strain annealing on TaC and HfC substituted alloys are also investigated. Lastly, we discuss the cost analysis on these alloys. Using the synthesis route presented here, a cost reduction of up to 74% can be achieved.

“…Дiя змiнного магнiтного поля може супроводжуватися скiн-ефектом, який полягає в тому, що струми, iндукованi внаслiдок намагнiчування, курсуватимемуть у поверхневих шарах аморфного сплаву [3,4]. Це явище узгоджується iз впливом на електрохiмiчну поведiнку, що визначається станом приповерхневого шару матерiалу [5][6][7][8][9][10].…”

У статтi дослiджено змiну властивостей об'ємного аморфного металевого сплаву на основi феруму (Fe55Ni8Co6)69-(Mo4Cr2V1)7-Al2-(P9C6B5Si2)22 пiд впливом змiнного магнiтного поля (ЗМП). Пiсля витримування у ЗМП простежується деяка змiна елементного складу зразкiв. Аналiз електрохiмiчних характеристик зразкiв сплаву в умовах циклiчного сканування потенцiалу електрода вказує на вищу тривкiсть дослiджуваного зразка в розчинi хлоридної кислоти. Найнижча корозiйна тривкiсть у водному розчинi NaOH. Модифiкованi змiнним магнiтним полем зразки сплаву (Fe55Ni8Co6)69-(Mo4Cr2V1)7-Al2-(P9C6B5Si2)22 мають пiдвищенну корозiйну тривкiсть у 0.5 М водному розчинi NaCl i HCl. Також пiсля перебування зразка у ЗМП його електроопiр знижується.Ключовi слова: об'ємнi аморфнi сплави, змiнне магнiтне поле, електрохiмiчнi властивостi, аґресивнi середовища, електроопiр.
