Abstract

Observations are reported on the structure of iron, laser surface-alloyed with carbon. Repeated laser surface-melting of iron pre-coated with DAG graphite has produced layers containing up to ∼6 wt % C, showing fine-scale white iron structures. Eutectic regions (interlamellar spacing ∼0.5μm) have been shown by transmission electron microscopy to consist of Fe3C + ferrite, the latter having formed by decomposition of austenite during solid state cooling. Regions of fine pearlite (spacing ∼55 nm) have also been observed. Carbon diffusion into the substrate during alloying produces a zone containing austenite and martensite.
