En el presente trabajo se describen los mecanismos básicos de deformación y fractura mediante los cuales se formaron los cráteres que se presentaron al impactar con varios tipos de proyectiles, una serie de blancos de acero (chapas), los cuales recibieron diferentes ciclos de tratamiento térmico. Cada uno de los cráteres se caracterizó mediante ensayos de inspección visual y metalografía, evaluándose a partir de los resultados la morfología típica que presenta el maclaje, el deslizamiento, las bandas de corte adiabáticas, el desconchamiento y el agrietamiento, producidos por el impacto de los proyectiles.
The present work describes the basics mechanisms of deformation and fracture, obtained by the impact of various projectiles on steel plates subjected to different cycles of heat treatment. Each one of the craters was evaluated by means of visual and metallography testing. In the craters was evaluated the morphology of twinning, slip, adiabatic shear bands, scabbing and cracking.
