Comparison of measured and calculated thicknesses of martensite and ledeburite shells around graphite nodules in hardened layer after laser surface remelting
After laser surface remelting of nodular iron 400-12 a modified layer consisting of remelted and hardened layers has been observed. Microscopy of the hardened layer was used to analyse the occurrence of martensite shells and/or ledeburite shells around the graphite nodules in the ferrite matrix. The size of the shells was subsequently supported by diffusion calculations.
