Is anyone familiar with the use of yield strength in creep zone?

Submitted by naveen_bhel on

I was going through some literature on AUSC steam turbine (operating temperature 700 deg C). In many of the papers i have seen that 400 MPa yield strength at operating temperature was used as material selection criteria for turbine rotor. At the same time some people are using Alloy 617 for same application, for which creep rupture is quite high (around 137MPa at 700 deg C) at operating temperature but yield strength is around 200 MPa.

Survey of Computing Platforms for Engineering Simulation

High Performance Computing

How many organisations are using Cloud Computing? Is the use of High Performance Technical Computing in engineering simulation set to grow in the next 5 years? Will Tablet PCs be powerful enough to run my application? What do my peers think?

These are typical questions asked by the engineering simulation community. Wouldn't it be great if we could take a snapshot of the type of computing platform we're using today and also predict where we will be in the next 5 years?

Perhaps some of those on this site have seen the news article on the BBC website yesterday about cracks appearing in the reactor at the Hunterston B nuclear power station. As the article states, cracking in the graphite bricks is predicted and the regulators are happy that the reactor is safe to operate.
