In-situ thermography and material characterization of scanning strategy effects in laser foil printing of Zr-based metallic glass

This paper aims to investigate the thermal behavior and amorphous stability of zirconium-based metallic glass (Zr65.7Cu15.6Ni11.7Al3.7Ti3.3) fabricated using the laser foil printing (LFP) technique. This study focuses on establishing the relationship between laser scanning strategies and melt pool cooling rates, em...

A Transfer-Learning and Continuous Optimization-Based Framework for Predicting Heat Treatment-Dependent Mechanical Properties of DED-Processed Low-Alloy Steels

Directed energy deposition (DED) of low-alloy steels involves strongly coupled effects among alloy composition, solidification behavior, and post-deposition heat treatment, making mechanical property prediction difficult when target-domain data are limited. This study develops a transfer-learning and continuous optimiz...
