Using X-ray diffraction analysis methods, the authors have studied the effect of stepwise isothermal annealing in the temperature range 150–670 C on the deformation microstructure parameters of cryodeformed VT1-0 titanium with micron, submicron, and nanoscale grain sizes. The structural states were obtained by rolling at liquid nitrogen temperature. This study discusses the influence of dislocations and twins as elements of deformation microstructure on the thermal stability of crystallite sizes (coherent scattering regions) and the magnitude of microdeformations. The dependences of microhardness on annealing temperature have been determined for samples in different initial structural states.

低温机械破碎产生的纳米晶和超细晶钛的热稳定性

作者使用 X 射线衍射分析方法研究了在 150-670 C 温度范围内逐步等温退火对具有微米、亚微米和纳米级晶粒尺寸的低温变形 VT1-0 钛的变形微观结构参数的影响。通过在液氮温度下轧制获得结构状态。本研究讨论了位错和孪晶作为变形微结构元素对微晶尺寸（相干散射区域）的热稳定性和微变形量的影响。对于不同初始结构状态的样品，已确定显微硬度对退火温度的依赖性。
