c7.s3.3

*Iron nail*: The microstructures indicate a remarkable conglomeration. One plate shows a weld running diagonally across the section, and along the edges of the weld there are carburised areas. Another notable point is that on one side of the weld the slag shows the effect of the forging, whereas on the other side there is no such sign. The specimen is covered with slip bands and has evidently undergone severe hammering, probably in its use as a nail. The carbon in the carburised areas exists as granular pearlite.
