A TEM Study on the Ti-Alloyed Grey Iron

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review

Abstract

The microstructure of graphite flakes in titanium alloyed cast iron is studied using electron microscopy techniques. Dual beam SEM/FIB has been used for TEM sample preparation. A TEM study has been carried out on graphite flakes in grey cast iron using selected area electron diffraction. Based on the selected area diffraction pattern analysis, crystallographic orientations are identified and compared. The orientation relationship between iron and graphite crystals at the interface is studied and discussed. It is found that graphite in the Ti-containing iron is extremely fine grained and that there is a high proportion of twins in the fine grained graphite. It appears that twinning and stacking faults are involved in the fine grained structure of the graphite. It is discussed how Ti addition affect crystal growth and may lead to formation of superfine graphite.
