    Boron-based aids are commonly introduced to tackle the unsatisfactory densification of SS316L parts fabricated by binder jetting (BJ) technology. However, there is scarce study on the effect of sintering aids on the mechanical performance. This work investigates the effect of B4C aids and sintering temperature on the mechanical performance and microscopic morphology of BJ printing SS316L parts. SS316L powders with a bimodal size distribution were adopted t... ...点击完成人机验证后继续浏览

    基于硼的助剂通常被引入以解决通过粘结剂喷射(BJ)技术制造的SS316L零件在致密度方面的不足。然而,关于助烧剂对机械性能影响的研究很少。本工作研究了B4C助剂和烧结温度对BJ打印SS316L零件的机械性能和微观形貌的影响。采用了具有双峰粒径分布的SS316L粉末以增强密度并减少形状变形。此外,添加B4C作为烧结助剂,在烧结过程中促进致密化。结果表明,双峰粉末有利于提高密度和改善烧结过程。随着B4C的加入,烧结温度显著降低。进一步研究表明,机械性能主要受最终密度和B4C含量的影响。综合考虑形状保持性和性能,预计1%质量分数的B4C和1250°C的烧结温度为最佳参数。
