MECHANICAL PROPERTIES AND FRACTURE SURFACE TOPOGRAPHY OF A THERMALLY EMBRITTLED STEEL.
Abstract
Tensile flow and fracture properties of 3140 steel in both the unembrittled and embrittled conditions are presented and discussed. Charpy impact properties which reflect the influence of thermal embrittlement on the transitional behavior are presented. Fracture surface topography is described. Quantitative data resulted in transitional curves for all three types of specimens utilized. This fracture surface topography also indicates that intergranular fracture has varying degrees of deformation, ductility, and energy required for separation. Several aspects of thermal embrittlement are discussed relative to the observations made in this study. (Author)
