High strength and low elastic modulus are critical properties of biomedical titanium alloys for manufacturing of load-bearing orthopaedic implants. Single phase beta Ti alloys can achieve low elastic modulus, but their strength is usually not high enough. Conversely, commonly used strengthening by alpha phase precipitation causes a sharp increase of elastic modulus. This paper presents an approach for achieving both high strength and low elastic modulus by tailoring the alloy composition.
