Thermal Characteristics of Amorphous Fe–Ni–Si–C Alloys
Differential scanning calorimetry (DSC) is used to study the phase transformations of four amorphous metal alloys based on transition metals Fe and Ni with additives of Si and C. The temperature dependences of the heat flux upon phase transformations are measured along with changes in the mass and specific heat capacity of amorphous alloys. Two phase transformations associated with the temperature of glass transition and complete crystallization are identified. The relative volume of the crystalline fraction of alloys heated to 1000°C is calculated. It is concluded there are nanocrystalline phases between the first and second phase transitions at heating rates of 0.1°C/s.
期刊介绍：
Bulletin of the Russian Academy of Sciences: Physics is an international peer reviewed journal published with the participation of the Russian Academy of Sciences. It presents full-text articles (regular, letters to the editor, reviews) with the most recent results in miscellaneous fields of physics and astronomy: nuclear physics, cosmic rays, condensed matter physics, plasma physics, optics and photonics, nanotechnologies, solar and astrophysics, physical applications in material sciences, life sciences, etc. Bulletin of the Russian Academy of Sciences: Physics focuses on the most relevant multidisciplinary topics in natural sciences, both fundamental and applied. Manuscripts can be submitted in Russian and English languages and are subject to peer review. Accepted articles are usually combined in thematic issues on certain topics according to the journal editorial policy. Authors featured in the journal represent renowned scientific laboratories and institutes from different countries, including large international collaborations. There are globally recognized researchers among the authors: Nobel laureates and recipients of other awards, and members of national academies of sciences and international scientific societies.
