Determination of Young's modulus, tensile and bend strengths and of fracture toughness in sintered materials is considered. The testing and interpretation procedures are analysed, especially for (near) brittle alloys. Formulae are presented for conversion of three and four-point bend to tensile strengths using the Weibull analysis and for calculation of maximum stress in a beam undergoing pure bending beyond the onset of plastic deformation.
