The research on tundish metallurgy has focused mainly on taking countermeasures to avoid and remove inclusions and the recent developments on tundish metallurgy were surveyed.The authers'advices for future development of tundish metallurgy were given in summary section.
Recent research on microstructural characteristics and oxidation behavior of Ti(1-x)AlxN thin film were surveyed. The Ti(1-x)AlxN coatings have three different phase regions, Bl structure for lower x value, wurtzite structure for higher x value and unidentified structure for medium x value. Based upon the selective oxidation mechanism the oxidation results of Ti(1-x)AlxN thin film with different Ti/Al ratio were predicated.
