Tangential eddy current array (TECA™) is a blend of multiplexed tangential coils and pancake coils, specifically designed to detect surface-breaking cracks in carbon steel welds. The TECA coil arrangement and operating mode yield unique eddy current signals from surface-breaking cracks in carbon steel, enabling the sizing of their depth.

Types and Causes of Concrete Deterioration - cement.org

Corrosion of reinforcing steel and other embedded metals is the leading cause of deterioration in concrete. When steel corrodes, the resulting rust occupies a greater volume than the steel. This expan-sion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling (Figs. 1 and 2).

Stress corrosion cracking - Wikipedia

The reason for the failures was stress corrosion cracking of metal fastening components made of stainless steel.
