Microstructure and mechanical properties of a medical TiNbZrSn titanium alloy with low elastic modulus were analyzed. The results show that, after solution treatment, the phase of the alloy is single β phase which size increases with solution temperature increasing. When the alloy is solutioned in the range of 780-900°C, the grain size coarsens, the strength decreases and plasticity increases respectively, while the modulus is kept about 40 GPa with solution temperature increasing.

The effects of melting time, crucible diameter and ingot mass on chemical homogeneity and the content of carbon and oxygen impurity in TiNi alloy were studied by vacuum induction melting in graphite crucible. The results show that the impurity content is increased with an increase in melting time and A/V ratio, and the effect extent on carbon content is much greater than that on oxygen. The A/V ratio has a close relationship with the crucible diameter and ingot mass under the coordinative condition. The 10-20 kg ingot with few impurity and excellent homogeneity can be obtained by adopting 10 min+15 min melting time plus 160 mm diameter crucible.
