Abstract Scope |
Tungsten is widely used in electronic, aerospace, military industries because of high melting point, hardness, thermal conductivity and low coefficient of thermal expansion. Tungsten is difficult to process due to its high melting temperature and brittleness at room temperature. Conventional powder metal methods for tungsten parts fabrication have a limitation for structurally complex parts production. Additive manufacturing techniques have considerable advantages in highly complex parts production with minimum needs in final processing. That can lead to perceptible production price lowering. Our development was concentrated on printing parameters optimization of tungsten powders, finding influence of printing parameters and powder morphology on the melting of powder and final densification of tungsten parts. Investigation on correlation between microstructure and mechanical properties in the printed tungsten parts was done with respect to powder morphology and printing parameters' setup. |
