COMPONENT OR COUPON FOR BEING USED UNDER HIGH THERMAL AND STRESS LOAD AND METHOD FOR MANUFACTURING SUCH COMPONENT OR COUPON

A component or coupon for use in a thermal machine under extreme thermal and mechanical conditions comprises an alloy material having a controllable grain size (d). A grain size distribution (d(X,Y,Z)) of the component or coupon corresponds to at least one of an expected temperature distribution (T(...

Beschreibung
Zusammenfassung:	A component or coupon for use in a thermal machine under extreme thermal and mechanical conditions comprises an alloy material having a controllable grain size (d). A grain size distribution (d(X,Y,Z)) of the component or coupon corresponds to at least one of an expected temperature distribution (T(X,Y,Z)), an expected stress distribution ( (X,Y,Z)) and an expected strain distribution ( (X,Y,Z)), which vary with geometrical coordinates (X,Y,Z) of the component or coupon, such that a lifetime of the component or coupon is improved with respect to a similar component or coupon having a substantially uniform grain size.
