I am doing this research with Prof. Zhan Chen and Ass ociate Prof. Sarat Singamneni here at AUT.\n\nBefore getting into project details\, in this presentation\, I will first introduce the place where I come from\, the Basque Country\, a small region in the northern of Spain w ith a wealthy economy based on a net of big and small and medium industria l companies that have been pushed to move on from the traditional sectors to Industry 4.0 in the last decades. The policies of the Basque Government have made this transition possible\, offering to academics and companies different instruments to work together under the framework “Basque Syste m for Research and Technology”. One of the members of the System is the University of the Basque Country\, the public institution where I teach pa pers on Materials Science in the Faculty of Engineering in Bilbao and lead a small research group working on Materials Engineering (eMERG).\n\n  \;\n\n(Research at AUT) Inconel 738 LC is a nickel-based superalloy offeri ng exceptional mechanical properties and corrosion resistance at high temp eratures. The alloy (In 738) is most commonly used for gas turbine blades and vanes for industrial use because its properties does not deteriorate i n the hot and corrosive environments in turbine operating condition. Tradi tionally In 738 parts are produced by casting but the emerging additive (3 D printing) technologies open new expectations to design parts with inner refrigeration channels for example that would allow working at high temper atures. However\, at this point of time\, poor weldability of In 738 has a ppeared as the main problem in additive manufacturing (of which SLM is a m ajor form). Finding process conditions to fabricate sound parts free of cr acks and other defects and suitable microstructure requires a better under standing of the rapid solidification process that occurs during SLM. Solid ified microstructure depends on the temperature gradient in the solid-liqu id interface\, on the solidification rate and on the cooling rate\, variab les that cannot be directly measured during the building process. Then\, a ll the features present in the microstructure must be carefully analyzed a nd related to process conditions (power\, scan speed\, layer thickness\, h atch distance\, scan strategy) and all together used to find out new piece s of knowledge to physical/metallurgical events that are taking place duri ng SLM. Progress on this study of SLM process-micro/macrostructure relatio nship will be presented in this presentation.\n\n \;\n\nBio:\n\nDr. Te resa Guraya is an assistant professor with the Faculty of Engineering\, Un iversity of the Basque Country\, Bilbao\, Spain. Her research interests in clude physical metallurgy of alloys\, new alloys and processes and new tec hniques for microstructural characterization. Dr. Guraya leads the researc h group eMERG (emerg.es)\, is PI in numerous projects and has published nu merous research papers.\n\n \; CATEGORIES:Meetings LOCATION:Room WZ141\, Auckland University of Technology\, 34 St Paul Street \, AUCKLAND\, .\, New Zealand X-APPLE-STRUCTURED-LOCATION;VALUE=URI;X-ADDRESS=34 St Paul Street\, AUCKLAN D\, .\, New Zealand;X-APPLE-RADIUS=100;X-TITLE=Room WZ141\, Auckland Unive rsity of Technology:geo:0,0 END:VEVENT BEGIN:VTIMEZONE TZID:Pacific/Auckland X-LIC-LOCATION:Pacific/Auckland BEGIN:DAYLIGHT DTSTART:20170924T030000 TZOFFSETFROM:+1200 TZOFFSETTO:+1300 TZNAME:NZDT END:DAYLIGHT END:VTIMEZONE END:VCALENDAR
