New titanium alloys were paid great attentions in China in recent 20 year.Many new Ti-alloys were designed,researched and developed. This paper reviews the R &D of new Ti-alloys in China in recent 20 years.Such as high strength (over 1100MPa) high toughness TC21 alloy with damage tolerance, high strength (over 1200MPa) high toughness Ti-5321 alloy, high strength (over 1250MPa) high corrosion resistant Ti-B19 and Ti-26 alloys，super high strength (over 1350MPa) high toughness Ti-1300 alloy , super high strength (over 1400MPa) high toughness Ti-1455 alloy , super high strength (over 1500MPa) Ti-1500 and Ti-1600 alloys , and also the high strength Ti-12LC alloy with low cost . Among the new alloys, TC21 has become the mainstay Ti-alloy for aircrafts; Ti-1300, Ti-26 and Ti-12LC alloys were used for aviation, aerospace and weapons. Ti-5321,Ti-1455,Ti-1500 and Ti-1600 alloys were just researched, and they are still in Lab. scale. |
