Fig. 1: Welding process of AA2024 and the ZCASW filler material.
From: High-strength and crack-free welding of 2024 aluminium alloy via Zr-core-Al-shell wire
a Schematic diagram of the welding process. b Longitudinal and cross-sectional schematic diagram and product of the ZCASW filler. c Schematic representation of the crystallographic data of α-Al and L12-Al3Zr15,26,27, illustrating how the lattice-matched Al3Zr phase could induce low-energy-barrier epitaxial growth of α-Al (OR1 represents orientation relationship 1 and OR2 represents orientation relationship 2).
