<正>In the past half century China has developed and formed her own system of high temperature materials for power, automobile and aero-engine industries in the temperature range from 550 。C 1 100 。C. These high temperature materials include heat-resisting steels, iron-base, nickel-iron-base and nickel-base superalloys. Some achievements in high temperature strength study, new technologies and new alloy development are also discussed.
