Advances in Additive Manufacturing Processes for Refractory Metal Materials
摘要
Abstract
Refractory metal materials exhibit outstanding high-temperature mechanical properties and high-temperature stability.It is often used in the preparation of heat-resistant parts,and is widely used in aerospace,defense industry and other fields.However,refrac-tory metals have a relatively high melting point and poor plastic ductility at room temperature.Therefore,there are problems such as processing difficulties when using traditional processing methods to prepare complex structural parts.Additive manufacturing is an emerging technology based on three-dimensional(3D)model data,using lasers,electron beams,special wavelength light sources,arcs and their various combinations as energy sources.The"discrete-stacking"forming principle is used to fabricate solid parts,and the size of the prepared parts can be from microns to meters,which provides a new way for the preparation of complex structural parts of refrac-tory metals.Firstly,the classification,characteristics,and applications of additive manufacturing technology were summarized in this article.Then,the current status of additive manufacturing technology for preparing refractory metals was introduced.The major chal-lenges in additive manufacturing of refractory metal materials were discussed.Finally,the research progress of additive manufacturing technology in regulating the microstructure and mechanical properties of refractory metal materials were summarized.And the future development direction of additive manufacturing technology of refractory metals was prospected.关键词
