Abstract

The effect of Al content on superelastic properties of Ti 75-xNb 15Zr 10Al x (x = 0-6 at%) quaternary β Ti alloys were investigated. And the effects of baking for coating or plating on superelastic properties were also studied. The alloys containing 3 and 4 at% of Al clearly exhibited superelastic behavior after aging at 453 and 553K, which are appropriate temperatures for industrial coating and plating, respectively. Ti 72Nb 15Zr 10Al 3 alloy exhibited the largest recovery strain of 2.5% due to superelastic behavior even after industrial coating and plating. In this quaternary alloy system, strange non-monotonical change of superelastic behavior as a function of Al content was also found.
