Objective
The positive results of this project include:
For water atomized powders/sintering - hot forming:
- Development of an efficient melt filtering practice
- Development of a processing route combining the sintering of a closed porosity preform and HIPing or hot-forging to eliminate the residual porosity.
This process results in a refined microstructure.
For gas atomized powers/deformation assisted densification:
Optimal HIP processing conditions leading to a fine distribution of carbides
- Development of the hot extrusion route to achieve a very small grain size and microstructure.
For both processes, knowledge has been gained on the optimization of heat treatment of the powder metallurgy high-speed steel grades.
POWDER PROCESSING IS CONSIDERED TO BE AN ATTRACTIVE ALTERNATIVE TO THE CLASSICAL PROCESSING ROUTE (CASTING + HOT WORKING) FOR THE PRODUCTION OF THE MAINLINE BEARINGS FOR GAS TURBINES OWING TO THE INHERENT BENEFITS OF POWDER METALLURGY: FINE MICROSTRUCTURE (CARBIDE AND GRAIN SIZE), UNIFORM DISTRIBUTION OF THE CARBIDES AND IMPROVED CHEMICAL HOMOGENEITY WHICH SHOULD IN TURN RESULT IN AN INCREASED FORGEABILITY. TWO COMMERCIAL HIGH SPEED STEELS, T1 AND M50 ARE CONSIDERED.
SEVERAL PROCESSING ROUTES ARE BEING INVESTIGATED:
- COLD PRESSING OF WATER ATOMISED POWDERS FOLLOWED BY VACUUM SINTERING (AND CONTAINERLESS HIPPING)
- HOT ISOSTATIC PRESSING OF GAS ATOMISED POWDERS, WHICH IS INHERENTLY MORE EXPENSIVE THAN THE FORMER PROCESS, BUT OFFERS MORE DEGREES OF FREEDOM TO ACHIEVE A COMPROMISE BETWEEN DENSIFICATION AND THE SIZE OF CARBIDES.
THE MICROSTRUCTURE OF THE MATERIALS, THEIR INTERNAL SOUNDNESS AND THE MECHANICAL PROPERTIES ARE COMPARED OF THOSE OF CONVENTIONAL EFR OR VIM-VAR MATERIALS.
