Abstract Concern about global warming motivates the reduction of greenhouse gas emissions from manufacturing but as yet the environmental impact of the whole powder metallurgy production chain has not been assessed. This paper therefore traces the flow of energy and material through the major powder metallurgy processes from liquid steel to final products and assesses the efficiency of both energy and material use. The results show that there is significant opportunity for reducing energy and material requirements in delivering products. Specific opportunities such as avoiding lasers in additive manufacturing or minimizing heat losses in powder sintering are proposed and evaluated.

钢铁粉末冶金的能源和材料效率

摘要 对全球变暖的担忧促使制造业减少温室气体排放，但尚未评估整个粉末冶金生产链对环境的影响。因此，本文追溯了能源和材料在从钢水到最终产品的主要粉末冶金工艺中的流动，并评估了能源和材料的使用效率。结果表明，在降低产品交付过程中的能源和材料需求方面存在重大机遇。提出并评估了特定的机会，例如在增材制造中避免使用激光或最大限度地减少粉末烧结中的热损失。
