describe trace analysis and explain its role in materials testing.
Expert Solution & Answer
Interpretation Introduction
Interpretation:
Describe trace analysis and its role in materials testing.
Concept introduction:
Trace analysis is a measurement of particles or substance at micro level.
Answer to Problem 1CO
Solution:
Trace analysis is a measurement of substance below one ppm and is used effectively in material testing like destructive testing methods like mechanical, fracture mechanics, chemical and metallurgical testing.
Explanation of Solution
Trace analysis is a measurement of substance below one ppm stages involved in trace analysis.
Planning: It should start with a discussion between the initiator and analyst. All the possible problems are defined during this process.
Sample collection and storage: In this process, mainly analyst is involved.
Sample preparation
Sample measurement.
Calculating the data.
Trace analysis is based on the sample of substance which undergoes various process. Though it is very difficult, it is utilized to get chemical composition of element that determines mechanical strength, fracture strength, mechanical properties etc.
Conclusion
Trace analysis is used in material testing.
