Effects of surface finish, of certain defects, and of repair of defects by welding on fatigue strength of 355-T6 sand-castings and effects of prior fatigue stressing on tensile properties /
Tests were made to evaluate the effects of various surface conditions, of certain defects, and of repair of some of these defects by welding upon the fatigue strength of an aluminum sand-cast alloy. The surfaces studied included as-cast, machined, grit-blasted, and shot-blasted surfaces. The unsound...

| Summary: | Tests were made to evaluate the effects of various surface conditions, of certain defects, and of repair of some of these defects by welding upon the fatigue strength of an aluminum sand-cast alloy. The surfaces studied included as-cast, machined, grit-blasted, and shot-blasted surfaces. The unsound conditions included different degrees of porosity and other kinds of defect sometimes present in castings which might affect their fatigue strength |
