High-Throughput Data Generation and Transfer Learning Enabled Microstructure-Property Integrated Design of Nickel-Based Powder Metallurgy Superalloy. [PDF]
An integrated transfer learning framework integrates CALPHAD simulations, diffusion‐multiple experiments, and literature data to predict long‐term microstructural stability and short‐term mechanical properties of Ni‐based powder metallurgy superalloys. Based on these model predictions, a high‐performance, low‐density alloy, USTB‐PM750, is designed from

An investigation into cracking in nickel-base superalloy repair welds [PDF]
The nickel-base superalloy Rene 80 is considered very susceptible to liquation and strain-age cracking. Material in the solutionised condition is welded using the Cold Metal Transfer, or CMT process (with ductile filler alloy) and autogenously using a
