Notched Tensile and Impact Fracture of Ti-15-3 Laser Welds
Metallurgical and Materials Transactions A, 2011 The notched tensile strength (NTS) and impact toughness of Ti-15V-3Cr-3Sn-3Al (β-type titanium alloy Ti-15-3) laser welds aged at temperatures ranging from 590 K to 866 K (317 °C to 593 °C) were determined, and the results were compared to those of unwelded Ti-15-3 plates aged at the same temperature.
