以高达1579 K/s的不同加热速率快速加热生物相容性Ti40 Cu 34 Pd 14 Zr 10 Sn 2块体金属玻璃，也称为快速退火。因此，通过先进的原位高能X射线衍射表征相形成。人们发现，不断变化的动力学约束可以用作故意改变晶相形成的工具。这种新的加工路线允许选择相结晶到预定的分数，因此，潜在地设计材料的微观结构，根据指定的属性配置文件。因此，快速退火提出了一种独特的合成路线，以设计具有良好生物力学相容性的材料。
The biocompatible Ti40Cu34Pd14Zr10Sn2 bulk metallic glass was rapidly heated, also known as flash-annealed, at varying heating rates up to 1579 K/s. Thereby, the phase formation was characterized via advanced in-situ high-energy X-ray diffraction. It has been found that the evolving kinetic constraints can be used as a tool to deliberately alter the crystalline phase formation. This novel processing route permits to select phases to crystallize to a predefined fraction and, thus, to potentially design the microstructure of materials according to a specified property-profile. Consequently, flash-annealing poses a unique synthesis route to design materials with, for instance, good biomechanical compatibility.
