Little work has been done on the effects of titanium on the properties of calcium S-G iron. In the previous informations on magnesium S-G iron, it was suggested that titanium in calcium S-G iron may have an anti-spherodizing effect of graphite. The present work has been carried out to determine the effects of titanium on the properties of calcium S-G iron and also the effects produced when misch-metal is used with calcium to counteract the anti-spherodizing effect of titanium.
Followings are the summary of the results obtained;
(1) Titanium restricts spherodization of graphite in calcium S-G iron, but is not so powerful as in the case of magnesium S-G iron.
(2) The combined use of a small quantity of misch-metal with calcium effectively counteracts the antispherodizing effect of calcium.
