摘要:
近年来，激光粉末床熔融（laser powder bed fusion, LPBF）作为一种先进的增材制造技术，已吸引了广泛的关注和研究。利用其高自由度的成形方式，可以设计制造出合适的冷却流道来对热作模具进行控温，从而提高模具的冷却效率及使用寿命。因此，LPBF技术在热作模具的成形制造中得到了广泛应用。H13钢具有高强度、高硬度、良好的耐回火性等优点，是热作模具最常用的工具钢之一。关于LPBF技术在H13钢中的应用一直是该领域的研究焦点，也已取得显著进展。基于此，首先阐述了LPBF制备H13钢的成形性能，分析了打印工艺参数对成形缺陷的影响，介绍了控制打印开裂的方法；其次，对沉积态与热处理态的LPBF成形H13钢的微观组织和力学性能进行介绍，详细论述了打印成形及后续热处理过程中的组织演化，在此基础上分析了微观组织对强度、硬度、塑性等方面的影响；同时也对LPBF成形H13钢在热作模具中的服役性能进行了总结，沉积态的LPBF成形H13钢具有良好的抗回火软化及抗热疲劳性能。最后，对具有随形冷却流道的LPBF成形H13钢热作模具在实际中的应用情况进行了总结分析，指出随形冷却流道在提高冷却效率、延长模具使用寿命等方面的显著优势。
Abstract:
In recent years, laser powder bed fusion (LPBF) technology, as an advanced additive manufacturing method, has attracted significant attention as a research focus. Due to its design freedom advantage, LPBF allows for the precise creation of cooling channels tailored to the molds contours. As a result, the cooling efficiency and service life of mold will be improved. Therefore, LPBF has been widely used in the manufacturing of hot work molds. H13 steel has become one of the most commonly used tool steels for hot work molds, owing to its remarkable attributes such as superior strength and hardness, along with exceptional resistance to tempering. The application of LPBF technology in H13 tool steel remains a significant area of investigation,where substantial advancements have been made. Based on this,the formability of H13 steel fabricated via LPBF has been described. The influence of process parameters on forming defects and the methods for controlling cracks have been analyzed. Then, the evolution of the microstructure during printing and heat treatment is discussed in detail, and the influence of the microstructure on plasticity, hardness and strength is reviewed as a result. In addition, the service performance of LPBFH13 steel in hot work molds is investigated, with the result that the as-built LPBF-H13 steel has excellent resistance to tempering softening and thermal fatigue. The application of LPBF-H13 steel hot work dies including conformal cooling channels has been concluded, its notable advantages in raising cooling efficiency have been noted.
