摘要
使用数据处理软件，在热分析仪上对经过国外和国内石墨化和球化改性剂处理的改性灰铸铁（GCI）和蠕墨铸铁（VGCI）进行了热分析（TA）。在 AO AVTOVAZ 铸铁厂条件下，构建了冷却曲线（凝固时间内测得的当前温度，T-t）和冷却曲线的导数（温度变化率与凝固时间的关系，dT/dt-t）。
Thermal Analysis of the Influence of the Cast Iron Modification Parameters on the Solidification Parameters
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.
