At first, My cordial respect to all members.

I need help regarding my research study.
I read a paper by Yaguchi, M., T. Ogata, and T. Sakai, Creep strength of high chromium steels welded parts under multiaxial stress conditions. International Journal of pressure Vessels and Piping, 2010. 87(6): p. 357-364.

From this paper, i selected a specimen. Now i need some mechanical properties.
Specimen: Welded 9 Cr steel Tube (9Cr-1Mo-V-Nb)
Parent material: P91 steel
Weld material: TGS-9Cb

I need the Mechanical tensile properties (At 650 C) for both P91 (Base Metal) and TGS-9cb( Weld Metal).

The properties are,

At 650 C

Poison’s ratio, ? = ?
Yeild Strength, ?y (MPa) = ?
Yeild Strain, ?y = ?
Ultimate tensile strength, ?UTS (MPa) = ?
Ultimate tensile Strain, ?UTS = ?

Without these properties, i can not go ahead with my research study. I have no other way but to ask you for help.

Any kinds of help would appreciated.

May God Bless you all.

Waiting for your valuable advice.

 

Hi mri44

I don't have any experience with both materials at high temperature. I think if you want to have accurate data. However, I can recommend to you some of the books that may contain such data.

Creep and Fracture in High Temperature Components : Design and Life Assessment Issues

you can also check the website: http://www.matweb.com to find the materials

Good luck
