自蔓延高温合成TiNi多孔体合金

为了开发新型的生体材料，本文对自蔓延高温合成TiNi多孔体合金——人造骨材料进行了研究。以单质钛粉和镍粉作原料，在氩气保护条件下，采用预热点燃模式和热爆模式制得了不同形态的多孔TiNi形状记忆合金。采用SEM和XRD分析了样品的孔洞特征和相组成，测试了其力学性能，并研究了合成条件参数与样品表面形貌和孔隙状态之间的关系。结果表明，用SHS法制备TiNi多孔体合金是可行的。

TiNi porous alloys prepared by SHS process

TiNi porous alloys were prepared as artificial bone by Self-propagation High-temperature Synthesis(SHS)in order to develop new bio-materials The mixture of titanium and nickel powder was ignited under the atmosphere of argon gas TiNi porous alloys with different microstructure were obtained by various ignition models such as preheating and heat explosion SEM and XRD were used to analysis pore characteristics and phase structures of samples Mechanical properties were also tested The results show that it is a useful method to prepare TiNi porosint alloys by SHS
