Achieving strong and ductile as-printed Ti-Cu alloys via tailoring eutectoid morphology

Materials Research Letters
The addition of Cu into Ti alloys forms brittle eutectoid lamellae and severely deteriorates ductility although it enhances strength and eliminates columnar grains during laser powder bed fusion process.

Horizontal welding quality control of the CO2 gas shielded welding

MATEC Web of Conferences, 2018
In the process of horizontal butt welding of CO2 gas shielded welding, the molten metal will squat under the effect of its own weight. Therefore, the upper part of the weld seam is very easy to produce undercuts, and the lower part is prone to defects ...
