Abstract

MEDINA-ALCINA, Fernando Iván. Effect of the environment on the interpretation of the metallic fracture surfaces. Iteckne [online]. 2016, vol.13, n.2, pp.169-173. ISSN 1692-1798.

Contamination of metallic fractures is detrimental, since the information related with the fracture process can be lost. As rust, humidity, foreign debris, etc., on metallic fracture surfaces can give false information about a failure event, the preservation of fractured samples is critical for failure analysis. In this investigation four (4) impact fracture surfaces of ASTM A-36 steel were placed outdoor in Puerto Cabello, Venezuela, for a period of 6 months. Then, an evaluation of the fractured surfaces was performed, using a stereoscopic magnifying glass, to observe the growth of corrosion products. The results indicate that the information related to the general fracture process can be lost because of the environmental impact.
