Their constitutive equations are obtained; 3 There are interactions among different orientation twins if deformation temperature is low, and cracks are induced which propagate along twin boundary. The titanium burning behavior was examined by DCSB method. The burning products and the burn-affected zone were examined by OM, SEM and X-ray diffractiometer. The studying results indicate that: 1 Ti40 alloy reveals good burn resistance, while both C. P. Ti and Ti-6-4 burn fast under the same ignition conditions; 2 Ti oxides, i. e. TiO, TiO〓 and Ti〓O〓, are the main products after C. P. Ti burn in the air. There are Al and V oxides besides Ti oxides after Ti-6-4 burn. The burning products of the binary Ti-Cr alloys are TiO〓, TiO and TiCrO〓; V oxides, i. e. VO and V〓O besides Ti oxides are produced after Ti40 does in the air, however, Cr oxides are not found; 3 Compared with C. P. Ti and Ti-6-4 alloy, the interface between burning products and matrix for Ti40 is tenacious, which is Cr-rich layer. This layer can retard the oxygen diffusion into the matrix, and reduce the burning velocity obviously. The key factor influencing burn is the tenacity of the burning products; 4 Effects of alloying elemental V on the burning velocity are not obvious. Cr content in binary Ti-Cr alloys increases (＞10%), the burning speed reduces, but binary Ti-Cr alloys do not possess burn resistance; 5 Titanium alloys can burn continuously among the oxygen-rich atmosphere. Their burning speed decreases with increasing the ratio of N〓 to O〓 and/or Ar to O〓. 6 The five burn stages and burning model are proposed, the burn resistant model is put forward, and two burn resistant mechanisms are proposed, i. e. fast dispersion heat mechanism and suspend oxygen diffusion mechanism. 7 Ti40 reveals good burn resistant behavior because of its low melting point, high thermal conductivity, tenacity of oxidation layer and so on.
利用直流电弧激发燃烧新实验方法，采用金相、SEM和X射线衍射仪等手段研究钛的燃烧行为，结果表明：1）Ti40合金具有优于纯钛和TC4的阻燃性能；2）纯Ti在空气中燃烧的主要产物是Ti的氧化物（TiO，TiO〓和Ti〓O〓）；TC4合金除有Ti的氧化物外还有Al和V的氧化物；Ti-Cr合金的燃烧产物中，除了存在Ti的氧化物外，还存在TiCrO〓的化合物；Ti40除有Ti的氧化物外还有V的氧化物，但不存在合金元素Cr的氧化物；3）与对比材料纯Ti和TC4合金相比，Ti40合金的燃烧产物与基体的界面较致密，为富Cr的氧化层，可阻碍氧向基体内扩散，使合金的燃烧速度明显降低；燃烧产物的致密性对阻燃至关重要；4）在本试验范围内，V含量的变化（25%～35%）对合金的燃烧速度没有明显影响；在Ti-Cr二元合金中，Cr含量升高燃烧速度降低，但Ti-Cr二元合金并不具有阻燃性能；5）钛合金在富氧环境中可持续燃烧，N〓/O〓流量比或Ar/O〓流量比升高，钛合金的燃烧速度降低；若钛合金燃烧，可用Ar气或N〓气灭火，N〓气效果更好；6）根据以上试验结果提出了钛合金燃烧过程的五个阶段和燃烧模型；建立了阻燃的物理模型；提出阻燃钛合金的快速散热和中断氧输送阻燃机理；7）Ti40合金具有良好的阻燃性能是因其熔点低、热导率高、氧化层致密等因素综合作用的结果。
