Brussels .27July 1977
Draft Council Decision
onapproval of "theaccession oftheEAEC
tothe Agreement onMaterials for Gas Turbines
(COST Projects 50/51/52)
(submitted totheCouncil "bytheCommission )
COM(77 )374final

Memorandum from theCommission tothe Council
On23November 1971 ,nine European States (Federal Republic ofGermany ,
France ,Italy ,Luxemburg ,Netherlands ,United Kingdom ,Austria ,
Switzerland andSweden )andtheEuropean Coal andSteel Community signed
theAgreement "Materials forGasTurbines "fortheimplementation of
aconcerted project (COST Project 50/51/52).This Agreement ,which
atfirst wastolast three yearsi made provision foranannual contribu­
tion bytheECSC of120.000 u.a .tobeused forresearch work tobe
carried outbytheJoint Research Centre .
On26July 1973 ,theCommission informed theSecretariat General ofthe
Council that theECSC ongrounds ofanegative opinion oftheECSC
Advisory Committee wasnotable toratify theAgreement .Inaproposal
addressed totheCouncil thesame day ,theCommission then endorsed that
theEuropean Atomic Energy Community should accede totheagreement on
"Materials forGasTurbines ".TheCommission submitted this plan to
theCouncil ,pursuant toArticle 101oftheEAEC Treaty .
Itthen became apparent that theJRCIspra inview oftheguidelines
for amultiannual research programme decided upon bytheCouncil on
14May 1973 (OJL153/73)could only perform arelatively limited
technical contribution totheCost Project 50/51/52.Therefore the "
Commission didnotmaintain itsproposal of26 .July butwithdrew it
on14February 1975 .
This situation haschanged since 25August 1975 ,when theCouncil
adopted aEAEC research programme inthefield ofHigh Temperature
Materials' tobecarried out atthePetten establishment .Inthe
JRC 1977-1980 multiannual research programme decided upon bythe
Council on29Marcl \1977 (COM (76)171)research work inthefield
of"High Temperature Materials "will becontinued .
TheCommission considers that theJRCthrough itsprogramme "High
Temperature Materials "canmake aworthwhile contribution tothe
execution oftheCOST 50/51/52project .Within theframework ofthis
COST project animportant section concerns the "High Temperature
Materials forGasTurbines ".Sotheresearch work on"High Temperature
Materials "which isincluded inthenewmultiannual programme of
theJRCcoincide foralarge part with theconcerted COST Action
50/51/52.Theprocedure toextend theCOST (50/51/52)Agreement from
l.July 1977 foranother period ofthree years basbeen launched .

COST 50/51/522.
Participation bytheJoint Research Centre totheCOST action
would provide theCentre withpositive benefits .Participation
bytheJRC :
-would contribute totheacquisition ofnewknowledge
-could generate newideas forthefuture orientation ofresearch
work
-Wouldprovide additional opportunities forcontacts outside the
establishment ,inparticular with non-Community European countries .
Participation bytheEuropean Atomic Energy Community would notresult
inadditional financial support forthebudget oftheCommunity .
Inconclusion ,theCommission proposes that theCouncil approves accession
oftheEAEC totheCOST project 50/51/52inpursuance ofArticle 101
oftheEAECTreaty andagrees ontheenclosed draft decision .

Draft Council Decision
approving theaccession oftheEuropean Atomic Energy Community
totheAgreement onMaterials forGasTurbines
(COST Pro.iects 50/51/52)
THECOUNCIL OPTHEEUROPEAN COMMUNITIES ,
Having regard totheTreaty establishing theEuropean Atomic Energy
Community ,andinparticular Article 101thereof ,
Having regard totheproposal from theCommission ,
Whereas nine European states andtheCommission ,onbehalf ofthe
European Coal andSteel Community ,signed anAgreement inBrussels
on23November 1971 relating totheparticipation ofthesignatories
thereto inCOST Projects 5^/51/52;
Whereas theCouncil ,byaDecision of29March 1977 »adopted a
research andtraining programme for theEuropean Atomic Energy
Community inthefield ofmaterials forhigh-temperatures for
1977-80 ;
Whereas this programme includes research activities that come under
thework covered bythe said Agreement :
J
Whereas theCommunity 'sparticipation inthis Agreement islikely to
assist theoptimum implementation oftheCommunity research programme ;
Whereas ,therefore ,theaccession oftheEuropean Atomic Energy
Community tothesaid Agreement should beapproved ;
Whereas theEuropean Coal andSteel Community isnot inaposition to
carry outtheformalities required under itsownrules ofprocedure
fortheimplementation oftheAgreement ,
HAS DECIDED :
Sole Article
Theaccession oftheEuropean Atomic Energy Community totheAgreement
onMaterial forCasTurbines (COST Projects 50/51/52)ishereby approved .

TECHNICAL ANNEX
tothedocument sent by^the Commission totheCounoil with aview
toparticipation oftheJoint Research Centre inCOST Projects 50/51/52
ThePetten establishment oftheJoint Research Centre shall be
responsible forcarrying outaresearch programme onhigh-temperature
materials which will include projects concerned ,ontheonehand ,with
thestudy ofproperties ofmaterials forhigh-temperature applications
and,ontheother ,with thecomparison anddissemination ofscientific
andtechnical information onthese materials .Byvirtue oftheir
direct link with theactivities carried outaspart oftheCOST project
onmaterials forgasturbines ,some ofthese activities could form
theCommission 'scontribution tothis project .
Specifically ,theCommission 'scontribution would cover three themes :
1.Effect ofprotective coatings onthemechanical properties of
certain nickel-based alloys .
Theexperimental work would embrace thestudy ofthefollowing aspects :
\
(i)effect oftheheat treatment involved inthecoaling process ;
(ii)stability ofcoatings intheabsence andinthepresence ,of
mechanical stresses andofvarious atmospheres j
(iii)behaviour ofcoated anduncoated alloys intheconditions
ofservice forwhich themachinery isdesigned ;
(iv)study ofindustrial components after use ;interpretation
offailures .
2.Study ofthestatistics ofcreep behaviour inalloys andtheir
effect ontheprediction ofalloy life .
Theaimofthisproject istodefine andmeasure theeffect onthese
statistics ofthemainvariables associated withthematerial an
with themeasurement technique .
3.Feasability study foradatabankonmaterials forgasturbines .
