WebDec 6, 2013 · The Bi-doped specimens exhibited fracture toughness values nearly 40 % less than the pure bicrystal specimens, as well as a change from transgranular to intergranular fracture. (3) All measured fracture toughness values were consistent with extremely brittle materials despite clear evidence of plastic deformation. WebApr 13, 2024 · To overcome this limitation, copper-based alloys are modified with the addition of grain refiners to improve the functional properties of the alloys by refining the grain structure, ... [13] and Zr [8] to CuAlBe alloys can improve their ductility, fracture toughness, and shape recovery by reducing the average grain size. For instance, ...

In materials science, fracture toughness is the critical stress intensity factor of a sharp crack where propagation of the crack suddenly becomes rapid and unlimited. A component's thickness affects the constraint conditions at the tip of a crack with thin components having plane stress conditions and thick components having plane strain conditions. Plane strain conditions give the lo… http://pubs.sciepub.com/materials/6/1/1/ how many 7/16 osb in a bunk
