This paper presents a report on the study of structural modifications LM4 processed by semi solid metallurgy. This was with the view to determine effects of degree of cold work, thermal treatment temperature and soaking time on the structural formations in the alloy. LM4 alloy was prepared and cast in sand mould into rods of diameter 12 mm and 200 mm in length. The cast rods were then heated to different temperatures which fall within the slurry region of the alloy. The heated samples were soaked at these temperatures for various times. There was also a set of non-treated control samples. The thermally treated rods were subjected to various degrees of cold work after which the metallographic examination of the samples was carried out. The observed microstructure of the alloy showed significant modifications.
