Is there a general rule or formula for the decrease in Young's modulus with rising temperature.
I am interested in metals, particularly stainless steels, aluminium and titanium. The temperature range I'm interested in is from -20C to
170C (-4F to 338F). Particularly the relative values at 20C , 150C and 165C (68F, 302F and 329F)I find that most material specifications supplied by manufacturers are less than useful in giving information like this.
No. Definitely not for all metals.

This handbook has property data with temperature.
Several years ago, a fellow employee graphed the moduli of several steels. There was no set pattern that could be applied to *all* metals.
That said and done, I have used a table "Moduli of Elasticity of Some Common Metals" in: Handbook of Engineering Fundamentals, 3rd, Eshbach, Wiley Engineering Handbook series, ISBN
0-471-24553-4 I lists temperature ranging from -200F to 2000F, but that range does not apply to each and every metal listed.Hope that helps, Jim Y
