Dr. Shuo Yin published in Materials Research Letters


Dr. Shuo Yin (STAM) has recently published a paper on improving the fatigue strength of Ti6Al4V materials in Materials Research Letters. Ti6Al4V has been widely used in biomedical industry due to their excellent mechanical and biological properties. It is also a candidate material of high interest for SLM 3D printing. Nevertheless, SLM Ti6Al4V typically has less favourable fatigue performance as compared with conventionally manufactured counterparts due to the inherent defects, tensile residual stresses and rough surface.

Researchers from STAM found that surface mechanical attrition treatment (SMAT) as a promising post-processing technology can improve the fatigue strength of SLM Ti6Al4V by 100% through inducing surface nanocrystallisation. This work was recently published in a highly prestigious journal, Materials Research Letters. This is an international collaborative work led by Dr. Shuo Yin from Trinity College Dublin, Prof. Jian Lu from City University of Hongkong and Prof. Min Liu from Chinese National Engineering Laboratory for Modern Materials Surface Engineering Technology.
