Primary and secondary crystallization of modified hypoeutectic chromium cast iron
Journal Title: Archiwum Odlewnictwa - Year 2010, Vol 10, Issue 2
Abstract
The paper presents investigations of crystallization of modified hypoeutectic wear resistant chromium cast iron which contains carbon about 2% and chromium on three levels (12%, 18% and 25%). Three substances were applied to the modification ( boron carbide (B4C), ferroniobium (FeNb) and mixture of ferroniobium and mischmetal (RE)). The investigations of crystallization were conducted the DTA method in DTA-C and DTA-Is testers. The influence on the course of the process of primary and secondary crystallization was observed.
