FYI--for steels, the tensile strength can vary from 200-2000 MPa, while the Fracture toughness (the material variable most dictating impact strength, previously stated by Jim) varies likewise by an order of magnitude (source text: Materials Selection in Mechanical Design, Michael F. Ashby). It was found that both ultimate tensile strength and fracture toughness are highly dependent on the chromium … The micro-tensile bond strength and interfacial fracture toughness tests did not correlate well. Ultimate tensile strength and fracture toughness experiments were conducted involving sub-zero chilled (using liquid nitrogen) cast iron containing 1.5% Cu, and chromium contents ranging from 0.0% to 2.0%. Fracture toughness increased linearly with decreases in both HI and spindle speed (Tribe) Optimal parameters for FT in X80 (tribe) Additionally, there is no evidence of grain coarsening in the HAZ. This information is evidently demonstrated in the next sketch (figure 2.3) [8]. When a material is pulled it stretches. Fatigue strength and fracture toughness of the Al–Cu matrix and TiC p /Al–Cu alloys. Tensile Strength vs Yield Strength m −3) ... Ductile materials have a fracture strength lower than the ultimate tensile strength (UTS), whereas in brittle materials the fracture strength is equivalent to the UTS.
