In metal forming processes, the material of forming tools and lubricants play a very important role. It not only influences the forming process but also affects the surface finish of the produced product. Moreover, the product cost is directly associated with the cost of tools and lubricants. The present research explores appropriate tool materials and suitable lubricants to be used in Elevated Temperature Incremental Forming (ET-IF) of Aluminium alloy for efficient results. For the purpose, tool materials and lubricants used in Incremental Forming processes at higher temperatures were identified from the literature. The physical and chemical properties of the reported tool materials and lubricants, along with the established applications, were studied. Besides, the availability and cost of the lubricants, as well as machinability of the tool materials, were also considered to identify a set of feasible tool materials and lubricants for possible ET-IF applications. Subsequently, experiments were carried out with the identified set of tool materials and lubricants. Based on the observations made and the experimental results, different tool materials and lubricants were evaluated. The work recommends Tool steel (EN-31) and Molybdenum disulfide mixture as the most appropriate tool material and lubricant, respectively.

在金属成型过程中，成型工具和润滑剂的材料起着非常重要的作用。它不仅影响成形过程，而且影响所生产产品的表面光洁度。此外，产品成本与工具和润滑剂的成本直接相关。本研究探索了在铝合金的高温增量成型（ET-IF）中使用的合适的工具材料和合适的润滑剂，以获得有效的结果。为此，从文献中确定了在较高温度下用于增量成型过程中的工具材料和润滑剂。研究了所报道的工具材料和润滑剂的物理和化学性质，以及已建立的应用。此外，润滑剂的可用性和成本 还考虑了工具材料的可加工性，以识别出一套可行的工具材料和润滑剂，以用于可能的ET-IF应用。随后，对确定的工具材料和润滑剂进行了实验。根据所做的观察和实验结果，评估了不同的工具材料和润滑剂。工作建议分别使用工具钢（EN-31）和二硫化钼混合物作为最合适的工具材料和润滑剂。
