Wheel Performance

Wheels used in freight and heavy haul operations are subjected to a combination of mechanical and thermal loads, both of which can contribute to increased rates of deterioration. Inadvertent overheating through the application of friction braking may also alter the residual stress distribution and increase the risk of wheel failure.

Key areas of expertise include:

• Metallurgical analysis of wheel defects and failures
• Cleanliness assessment using ultrasonic phased array testing
• Destructive and non-destructive measurement of residual stresses
• Assessment and qualification of wheel materials to industry requirements
