Intergranular corrosion (IGC), also known as intergranular attack (IGA), is a common local corrosion. Corrosion develops along the crystal grains boundary or its adjacent area of a metal or alloy, and the corrosion of the grain itself is very slight. This corrosion greatly weakens the bonding force between the crystal grains, and in severe cases, the mechanical strength can completely disappear. Stainless steel, nickel-based alloy, aluminum alloy and magnesium alloy are all materials with high sensitivity to intergranular corrosion. In the case of heating, the welding process will cause the problem of intergranular corrosion. Intergranular corrosion (IGC) is an effective test to screen the corrosion resistance of materials under certain conditions. T,C&A Lab's dedicated experts have professional corrosion testing capabilities to help you choose the most appropriate solution to evaluate the intergranular corrosion resistance of your materials and guide the thermomechanical and welding processes. Learn more at https://tcalab.alfa-chemistry.com/material-testing/intergranular-corrosion-igc-testing.html​
