| Zusammenfassung: | The invention relates to a reinforced aluminum alloy additive manufacturing method. The reinforced aluminum alloy additive manufacturing method comprises the steps that titanium diboride powder and aluminum alloy powder are mixed to obtain mixed powder; the mixed powder and grinding balls are mixed together for ball milling, and titanium diboride reinforced aluminum alloy powder is obtained; tiling the titanium diboride reinforced aluminum alloy powder to obtain a current layer; scanning and sintering the preset area of the current layer by using a laser beam to melt the titanium diboride reinforced aluminum alloy powder in the preset area; returning to execute the powder tiling step and the laser beam scanning sintering step so as to form a 3D printing structure in a preset shape through layer-by-layer superposition; and during laser scanning sintering, the laser volume energy density is in a range of 87.96 J/mm < 3 > to 140.74 J/mm < 3 >. By using the reinforced aluminum alloy additive manufacturing method, |
