摘要

金属化球团是多孔体，其变形不服从金属的塑性变形规律。我们提出了旨在研究金属化球团在热状态下变形过程中孔隙率随加热温度和压力变化的实验结果。在研究过程中发现，由于压块，热金属化球团的孔隙率降低了2-2.5倍，这是由于开孔体积的减少。

Investigation of porosity changes in a metallized pellet in the process of deformation

Metallized pellets are porous bodies and their deformation does not obey the regularities of plastic deformation of the metal. We present the results of experiments aimed at studying the changes in porosity of metallized pellets in the course of their deformation in the hot state, depending on the temperature of heating and pressure forces. In the process of investigation, it was discovered that, as a result of briquetting, the porosity of hot metallized pellets becomes 2–2.5 times lower, due to a decrease in the volume of open pores.
