Joint ASM/AWS Event: Cladding Nickel Alloy on Steel - Dr. Hassan Saghafifar
Wed, 22 March 2017, 6:00 PM – 9:00 PM PDT
ASM BC CHAPTER MARCH TECHNICAL MEETING
Join us on Wednesday, March 22nd for dinner at BCIT's Habitat Pub and our Technical Meeting. This month we are please to offer a joint ASM/AWS event. We are honored to have Dr. Hassan Saghafifar present.
Dr. Saghafifar graduated from his M.Sc. in 1998 in Materials Characterization and Selection with distinction from Isfahan University of Technology (IUT) in Iran. He worked in various Oil & Gas and Power Generation related industries up to 2007 as quality control engineer and obtained considerable experience with different standards like ASME, ASTM and AWS and quality management standards (e.g. ISO 9000 and ISO 14000 and OHSAS 18000).
In 2007 Dr. Saghafifar started his Ph.D. program in University of Nottingham in Materials Engineering and Material Design in U.K. and his project was concerned with characterization of steel and superalloy cladding for electricity generating plant. After graduation in 2012, Dr. Saghafifar worked as a Welding Engineer in Cameron sub-sea section in Leeds for over 2 years dealing with cladding. In 2014, he started his job in Islamic Azad University Tehran Branch, in Iran as a lecturer teaching courses in Welding and Material Characterization up to 2016, June when he moved to Vancouver.
TOPIC: "Cladding Nickel Alloy on Steel"
Ni-based superalloys weld overlays are widely used to significantly reduce high temperature corrosion problems of ferritic steel components under service conditions. Welding a nickel alloy (IN625) on a 2.25Cr1Mo steel enhances its service life in the highly corrosive environment.
For the purposes of studying the effects of high temperature service on the microstructure, a series of thermal exposure tests at 650˚C was performed for different times from 1 day up to 128 days. The microstructural evolution was studied using a combination of analytical techniques along changes in hardness profile across the interface.
Microstructural evolution in the steel region is related to the carbide transformation process and carbon migration. Experimental observation confirmed that a network of alloyed M23C6 carbide precipitates was formed at the interface in the steel side which are believed to interrupt the carbon migration across the interface.
