... at high temperatures. Alloys that contain low-melting-point phases (such as gamma-prime strengthened nickel-base superalloys) tend to be difficult to deform and have a limited range of working temperature. In general, as the solute content of the alloy increases, the possibility of forming low...

... a change in shape and dimensions. On close examination, however, it is clear that deformation resulting from the applied load causes secondary stress and strain states that vary from point to point throughout the deforming workpiece. These stress and strain states may include tension, so fracture...
