Latent Heat of Hastelloy X 1

[CoffeeMan]

What is the latent heat of fusion of the nickel superalloy Hastelloy X?
I know specific heats up to about 1100 celsius, and I can use trendline extrapolation to find ones at temps up to 1260-1355 C (melting range) if I want. But I haven't been able to find any data on latent heat for this material.

I'm not certain but would it not be OK to simply add up the latent heats of each element times the percentage of each element in the alloy?

Hmmm... superposition of latent heats? That's a fine idea, wish I had thought of it. Since the target of my calculations will not involve endangering human life or sending a 3 billion dollar craft to the moon, I suppose a little bit of error can be allowed for.

Thanks for your input sreid!

The producer of Hastelloy, Haynes International, may be able to provide the information that you need. I suggest contacting them:

Yes, I did email them but unfortunately they had nothing. Here is what they did have, for anyone who might be interested:

"We do not have the exact parameter you are seeking for Hastelloy X. As an approximation ,you might consider the value for latent heat of fusion for nickel, given in various textbooks on metallurgical thermochemistry (e.g 4.22 kcal/mole in Kubaschewski and Evans). Another suggestion might be to contact a University Professor adept at welding metallurgy (Tom Eager at MIT, tweager@mit.edu or Bob Messler at RPI, messl@rpi.edu"
