Sampling And Machining Miniture Test Specimens

　Evaluating strength of boilers and gas turbines and effectively assessing their remaining life in the areas exposed to high-temperature environment requires taking a small amount of the material for testing directly from the area in interest. Depending on each purpose, KMTL extracts very small samples from the surface layer, cracked part and other small areas with the least damage to the object, and machine them into miniature test specimens of various configurations.
