Abstract
Thermal analysis (TA) of modified gray cast iron (GCI) and vermicular graphite cast iron (VGCI) treated by foreign and domestic graphitizing and spheroidizing modifiers is conducted on a TA device using data processing software. Cooling curves (current temperature measured in solidification time, T–t) and the derivatives of the cooling curves (temperature change rates vs. the solidification time, dT/dt–t) have been constructed under the AO AVTOVAZ iron foundry conditions.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
