Final Report
  An executive summary of the final report is now available: see the "Documents" section.
 
17th PLANSEE International Conference on High Performance P/M materials (PLANSEE Seminar 2009)
  Oral communications will be presented by former ULTMAT partners at the PLANSEE Seminar which will be held in REUTTE (Austria) from 25th to 29th May 2009.

2008

2008 MRS Fall Meeting
  Oral communications will be presented by former ULTMAT partners at the 2008 MRS Fall Meeting which will be held in BOSTON (MA, USA) from 1st to 5th December 2008.
 
19th AeroMat Conference and Exposition (AEROMAT 2008)
 

Oral communications will be presented by ULTMAT partners at the AEROMAT 2008 conference which will be held in AUSTIN (TX, USA) from 23rd to 26th June 2008.

 
New achievements: investment casting
 

Successful investment castings have been performed. Below is a picture of a 320 mm high unshrouded blade made of a Nb-silicide based alloy (see also below the first castings obtained in 2006-2007).


In a first attempt for casting such a large blade, the airfoil of a shrouded blade broke during cool down, due the tensile stress generated by the CTE mismatch between alloy and ceramic mould. A new mould design would however allow the investment casting of a shrouded blade.

 
2008 World Congress on Powder Metallurgy and Particulate Materials (World PM 2008)
 

One oral communication will be presented by a ULTMAT partner at the World PM 2008 congress which will be held in WASHINGTON D.C. (USA) from 8th to 12th June 2008.

New achievements: Powder metallurgy and machining
 

Starting from an elemental powder blend, MoSiB billets have been manufactured (cold isostatic pressing, sintering and hot isostatic pressing). Machining trials have been performed (EDM, grinding, milling, etc.) and turbine component mock-ups have been machined.

International Conference on Powder Metallurgy & Particulate Materials (PowderMet2007)
 

ULTMAT has participated in the International Conference on Powder Metallurgy & Particulate Materials (PowderMet 2007) which was held in DENVER (CO, USA), from 13th to 16th May 2007.

New achievements: investment casting
 

Investment casting of blades made of niobium silicide based alloy has been successfully performed. Investment casting is the processing technique currently used for nickel-based superalloy blades and vanes.
The challenge is here the high melting temperature of the niobium silicide based alloy (> 2000°C), in comparison with the melting temperature of nickel-based superalloys (<1400°C).
Small foil thicknesses (~ 1 mm) can be achieved.

 



(total height ~ 120 mm)
