    摘要:

    基于一般快速成型原理，采用激光熔化同軸輸送的316L不銹鋼粉末，在沉積基板上逐層堆積出薄壁金屬零件，所制零件組織致密，成分均勻，具有快速凝固組織特征，力學(xué)性能與鑄態(tài)及鑄造退火態(tài)相當(dāng)，可滿足直接使用要求。

    Abstract:

    Based upon the mechanism of conventional rapid form, the thin wall parts of 316L stainless steel were obtained through the laser melting of metallic powders which were delivered coaxially and then deposited on the substrate layer by layer. The obtained microstructure is fully dense and evenly distributed with the characteristic of rapid solidified microstructure. The mechanical properties are equivalent to that of casting and wrought annealed materials, suitable to the requirement for real usage.
