High-temperature creep of GTH (Gottsu-Tsuyoi-Hakkin)

Platinum and platinum–rhodium alloys are widely used in glass industry. In order to strengthen their high temperature creep properties, some O.D.S. alloys are developed. G.T.H. and G.T.H.R., which are the trade names of our O.D.S. alloys and developed by Tanaka Kikinzoku Kogyo K.K. in Japan, are crept and their high temperature properties are examined. According to the results, the initial stress of their creep rupture is several times higher than those of normal cast metal (and alloy) comparing with the similar rupture time.
