| 发明名称 | Method for the thermomechanical treatment of a titanium alloy, and resulting alloy and prosthesis | ||
| 摘要 | According to a thermomechanical treatment process for a titanium alloy including between 23 and 27% niobium in atomic proportion, between 0 and 10% zirconium, and between 0 and 1% oxygen, nitrogen and/or silicon, the following steps are performed: a) an increase of a sample of the alloy to a temperature higher than 900° C.,b) a fast quench,c) a severe cold strain,d) an ageing treatment at a temperature included between 200 and 600° C., the time of the ageing treatment being included between 10 seconds and 10 minutes. Alloy obtained by this process and prostheses made from such an alloy. | ||

| 主权项 | 1. Thermomechanical treatment process for a titanium alloy including between 23 and 27% niobium, between 0 and 10% zirconium, and between 0 and 1% oxygen, nitrogen and/or silicon, the ratios being expressed in atomic proportions, process wherein the following steps are performed: a) an increase in temperature of a sample of the alloy to a temperature higher than 900° C., b) a fast quench, c) a cold strain higher than a true strain of 3, d) an ageing treatment at a temperature included between 200 and 600° C., the ageing treatment time being included between 10 seconds and 10 minutes. | ||
