| Abstract: | easonable multistage complex modification with Al-Ti-Ca--RE alloy has been developedand the effectiveness is discussed. It is shown that the strength, the DUctility and the toughnessachievded are 15%, 20% and 40% higher respectively than those of the conventional high manganesesteel because of the grain refinement,the liquid steel purity and the improved morphology and distribution of non-metallic inclusions. An spplication of the caterpillars cast with the modified steel showsthat the service life is 20% longer than the specified one. |
