When a sample is tested to fracture it may fail either by Brittle Fracture or by Ductile Fracture. In ductile fracture, considerable plastic deformation before the material fractures. The fracture ...

It is seen (a) that the ultimate tensile strength of these alloys increases as the carbon content is increased and that the yield stress reaches a plateau at about 0.6 wt 5 carbon content in the alloy ...

At temperatures down to -124 degrees C, the crystals were fully ductile, giving chisel-edge fractures and 100% reduction in area. At -196 degrees C, depending on the orientation of the stress axis, ...
