Researchers have formulated equations of ductile fracture to simulate and predict defects in cold-forged parts, e.g., the Cockcroft–Latham criterion. However, these are not applicable certain cases forged products. This study formulates a new equation for predicting fractures with better prediction accuracy than convention by which cost trial-and-error design can be reduced. The is expressed as...

Beta-titanium alloys containing only fully biocompatible elements are very perspective materials for production of bioimplants. They have good properties for use as biomaterials, including above mentioned biochemical compatibility, low elastic modulus (important for biomechanical compatibility), in comparisson with previously used alloys. Moreover they are suitable for forging. Perspective meth...
