中文摘要：
纯 alpha-Ti 样品以极其高的率(约 10 ~ 6K/s ) 被加热到阶段地区由一很快在 electro-pulsingtreatment 熄灭跟随了的贝它的温度。在处理以后，测微计厚的薄片状的基础在原来的 equiaxed alpha-Ti 以内被产生粗糙的谷物。错误取向到对面邻近的薄片具有一些度。极其细小的薄片状的基础在高温度与一短暴露时间在很快熄灭热的过程期间从非平衡 alpha-beta-alpha'phase 转变发源。当一样的张力的粘性(elongation-to-failure ) 相对原来的样品被维持时，张力的力量被大约 100 MPa 由于极其细小的薄片状的基础的形成增加。加强的效果能被亚边界的高密度归因于脱臼运动的有效阻塞。
英文摘要：
The pure α-Ti samples were heated at an extremely high rate （～10^6 K/s） to the temperature of β phase zone followed by a rapidly quenching in an electro-pulsing treatment. After the treatment, micrometer-thick lamellar substructures were generated within the original equiaxed α-Ti coarse grains. Misorientations across adjacent lamellae are of a few degrees. The ultrafine lamellar substructures originated from a non-equilibrium α-β-α’ phase transformation during rapidly heating-quenching process with a short exposure time at high temperatures. Tensile strength was increased by about 100 MPa due to the formation of the ultrafine lamellar substructure while the same tensile plasticity （elongation-to-failure） was maintained relative to the original sample. The strengthening effect could be attributed to the effective blockage of dislocation motions by a high density of sub-boundaries.
