Microstructure and Mechanical Properties of Biomedical Near-β Ti Alloy TLM with Nanostructure by ARB Process

摘要：

The composite foils with nanograins of novel near-β type biomedical Ti alloy Ti-(1. 5~4. 5)Zr-(0. 5~5. 5)Sn-(l. 5~4. 4) Mo-(23. 5~26. 5)Nb (TLM in short)were prepared by near Accumulative Roll-Bonding process (ARB). The process, microstructure and mechanical properties of TLM alloy foils were studied and discussed. The results shows that the average grains dimension of TLM alloy foils (0. 2mm) can reach about 80nm after 97. 5％ severe plastic deformation (SPD). The TLM alloy materials with nanostructure possess higher tensile strength,lower elastic modulus and higher elongation compared with coarse-grained materials after solid solution and aging strengthening heat treatment.
