- 摘要:
- 激光选区快速成型机直接烧结覆膜砂抗拉试样，测试试样在不同后处理保温温度下抗拉强度，利用扫描电
镜观察了试样的表面和断口形貌。 结果表明，最佳的后处理为保温温度 240 ℃，保温时间 15 min。
The tensile strength of coated sand samples was tested at different post-treatment temperatures. The surface and fracture morphology of the samples were observed by scanning electron microscopy (SEM). The results show that the optimal post-treatment temperature is 240 ℃for 15 minutes.
