【摘要】：正脊椎固定器在较狭窄的手术视野中应能够随着脊椎侧弯的程度进行简单的形变,且不应产生大的回弹。然而为了抑制应力屏蔽效应,又要求其具有低的弹性模量。为此,大阪大学H.H.Liu研发了通过具有高弹性模量的变形诱发ω相来控制的自调整型Ti-9Cr-0.2O合金,在变形区可以获得高弹性模量,未变形区仍维持低弹性模量。为改善合金弹性模量的自调整特性,探讨了变形诱发ω相的形成机理。
[Abstract]:The ortho-spinal fixator should be able to perform simple deformation with the degree of scoliosis in a narrower surgical field, and should not produce a large rebound. However, in order to suppress the stress shielding effect, it is required to have a low elastic modulus. H. Liu, Osaka University, developed a self-adjusting Ti-9Cr-0.2O alloy controlled by deformation-induced 蠅 phase with high elastic modulus, which can obtain high elastic modulus in the deformation region. In order to improve the self-adjusting property of elastic modulus of alloy, the formation mechanism of 蠅 phase induced by deformation is discussed.
