对全球变暖的担忧促使制造业减少温室气体排放，但迄今尚未评估整个粉末冶金生产链对环境的影响。因此，本文追踪了从钢液到最终产品的主要粉末冶金过程中的能量和物质流动，并评估了能量和材料的使用效率。结果表明，在交付产品时，有很大的机会降低能源和物质需求。提出并评估了具体的机会，如在添加剂制造中避免激光或在粉末烧结中最大限度地减少热损失。(C)2018年作者。爱思唯尔出版公司(Elsevier B.V.)
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. (C) 2018 The Authors. Published by Elsevier B.V.
