UT Reference Block for Nickel based and Cobalt Based

Good Morning guys

Im get the problem for wall thickness with ultrasonic method. The part is nickel and cobalt based (nimonic c263 and hasteloy x). This is new case in my company. This job is urgently. Then im already have reference block in SS and aluminum.

So any sugesstions approach method for measure nickel and cobalt based wall thickness with SS and aluminum reference block or any other method ??

If any reference or standard please tell me. :D

Thank you guys. I hope i get answer from this forum :D

Regards.

Dear Sir,

The velocity of the Nimonic alloys varies with the composition and heat treatment. So they cannot be equated to SS. The velocity of SA 316 ss comes close to one of the high nickel alloys. But this is taking a high risk as heat treatment is a definite factor that influences the Ultrasonic velocity .

Under the circumstances the best thing that can be done is to look for two parallel surfaces on the component and physically measure the thickness. ( You may use various types of calipers in case you do not find the parallel surfaces readily). Then measure the thickness Ultrasonically and adjust the velocity till it is equal to the physically measured value.

Verify your results on another parallel surface.

Hope you find such useful surface/s.

Best wishes,

P V SASTRY

Thank you so much for your information sir Sastry.

I will consider this method, thank you

but, how if i used hasteloy x plate with thickness 5mm as the reference block for the part.

whether this can represented to get velocity for correct measurement ??

Thank you.

Sorry for the belated response.

The Hastelloy X has Chromium, Molybdenum,iron as major alloying elements where as Nimonic C263 has Chromium, Molybdenum, and Cobalt as major alloying elements.

As I mentioned previously the Ultrasonic velocities differ widely based on composition and heat treatment as well as the degree of working ( cast or wrought (how much wrought)).

From the literature I see that the UT velocity of Hastelloy is 5791 meters/second.

It depends on what degree of accuracy you are looking in the thickness measurements of your components.

If you are looking for high accuracy then you have to use the block with same composition and heat treatment etc. Or the Parallel surfaces in the same component with measurable thickness.

Best wishes
