Dr. R. Donnini and Dr. D. Ripamonti from Italian CNR-IENI (Institute for Energetics and Interphases, National Research Council, Italy) visited IMR during Sept. 16-20, 2013. Their visit is part task of the 2011-2013 CAS-CNR bilateral scientific joint project titled “Correlation between Microstructure and Mechanical Properties of Advanced Nickel Base Superalloys”.

In past two years, both sides of IMR and IENI focused on creep, fatigue, fracture mechanisms and micro-structural evolution of the low dense, high damage-tolerant single crystalline superalloy DD417G at high temperature. Long-term experimental tests added up to 20,000 hours had been carried out on the creep and low-frequency fatigue at high temperature for this alloy.

During this visit, the Italian scientists and Professor ZHOU Lanzhang, who is the Chinese leader of the joint project from IMR, exchanged their recent progress on the project, and then made a plan for further work. The Italian guests also visited Shenyang National Laboratory for Materials Science and the exhibition hall of IMR. Additionally, both of them had popular lectures in IMR.

Dr. D. Ripamonti had a lecture titled “Creep behaviour of aged Nimonic C263 superalloy and creep modelling for a single crystal superalloy”

Dr. D. Ripamonti answered questions put forward by faculty and graduate students from IMR

Dr. R. Donnini had a lecture titled “Micro-structural and mechanical characterizations for high strength metal materials”
