【摘要】：正脊椎固定器在較狹窄的手術視野中應能夠隨著脊椎側(cè)彎的程度進行簡單的形變,且不應產(chǎn)生大的回彈。然而為了抑制應力屏蔽效應,又要求其具有低的彈性模量。為此,大阪大學H.H.Liu研發(fā)了通過具有高彈性模量的變形誘發(fā)ω相來控制的自調(diào)整型Ti-9Cr-0.2O合金,在變形區(qū)可以獲得高彈性模量,未變形區(qū)仍維持低彈性模量。為改善合金彈性模量的自調(diào)整特性,探討了變形誘發(fā)ω相的形成機理。
[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.
