About
Bai Chang is a materials science researcher whose work centers on the microstructure characterization and processing of lightweight magnesium alloys, particularly through advanced laser welding techniques. His most cited study, "Microstructure Characterization of AZ31B Mg Alloy Welds Processed by Nd:YAG Laser Welding" (2017), represents a foundational contribution to understanding how high-precision laser welding affects the structural integrity of AZ31B alloys. Using six-axis robotic welding systems combined with scanning electron microscopy and energy dispersive spectroscopy, Chang systematically analyzed the microstructural evolution and phase distribution in auto-welded joints, revealing how laser parameters influence grain refinement and defect formation. This work has accumulated 3 citations, establishing a reference point for subsequent studies on weldability of magnesium alloys in automotive and aerospace applications. Chang's research addresses critical challenges in joining lightweight materials, where traditional welding methods often produce excessive porosity or cracking. His detailed characterization of the laser-material interaction zone provides practical insights for optimizing welding parameters to achieve stronger, more reliable joints. By bridging fundamental metallurgy with applied manufacturing processes, Chang contributes to the broader goal of enabling wider adoption of magnesium alloys in weight-sensitive industries.
