Abstract

Rolled composite complex modifiers have been tested and compared with conventional modifiers (most often used for the production of castings from high-strength pig iron) to reveal that the former have better plasticity. The effect of modifies produced with different methods but having components with close compositions on the structure and mechanical properties of high-strength iron with spherical graphite. There are also results of field tests of cast ploughshares made of bainite high-strength pig iron using rolling modifiers.
