Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Currently, Ti-Mo, Ti-Nb, Ti-Ta and Ti-Zr-based β-titanium alloys have been widely studied. Compared with other titanium alloys, these alloys can achieve lower elastic modulus and higher strength. Since Ti-Nb alloy has low elastic modulus and good shape memory effect, it is the most promising medical titanium alloy to develop and utilize. Beta titanium alloys with the elements of Nb,Ta,Zr are being studied as the most important biomedical materials. This chapter presents the microstructure and mechanical properties of TiNbTaZr titanium alloy. The results show that the TiNbTaZr β titanium alloy with lower elastic modulus and non-toxic alloying elements has much more important application in biomedical field. The Ti35Nb2Ta3Zr β titanium alloy is studied and the alloy has the complex properties of lower elastic modulus, high strength, high elongation and excellent shape memory effect. Compared with direct rolling, cross rolling is beneficial to the isotropic of the microstructure and mechanical properties.
