低温机械合金化（CMA）已被证明是一种有效的手段，用于生产复合粉末与共连续相贯穿每个颗粒。通过SLS固结这些复合颗粒提供了形成具有共连续微观结构的部件的可能性。研究了球磨时间和PEEK体积分数对激光烧结尼龙12-PEEK共混物微观结构和力学性能的影响。在这两种共混物中，PEEK相被并入以增加机械强度、刚度和热挠曲温度。利用透射电子显微镜和扫描电子显微镜研究了CMA粉末和激光烧结件的微观结构。
Cryogenic mechanical alloying (CMA) has been shown to be an effective means for producing composite powders with co-continuous phases throughout each particle. Consolidation of these composite particles via SLS presents the possibility of forming parts with a co-continuous microstructure. In this work the effects of milling time and PEEK volume fraction on the microstructure and mechanical properties of laser sintered Nylon 12-PEEK blends is studied. In both blends, the PEEK phase is incorporated to increase mechanical strength, stiffness and heat deflection temperature. Transmission electron microscopy and scanning electron microscopy is utilized to investigate the microstructure of the CMA powder and laser sintered parts.
