Objectives. When creating models of system dynamics, the basic construct at the design stage is the representation of the process under study in terms of a causal relationship consisting of a positive feedback loop and a negative feedback loop. The c

Hard-alloy dies with channels of the traditional form and dimensions have been shown to have inadequate resistance to fracture during the drawing of nichrome and ferronichrome strips. Their durability can be improved by favorably directing the forces

The available die assembly designs for hydrodynamic drawing cannot be used to produce difficult-to-form nichrome strips, which are employed as heating elements in commercial resistance furnaces. Due to intensive cold work hardening, the σu of nichro

To eliminate the problems of existing direct-chill molds (DCMs) used to cast ingots of complex-alloyed bronzes and brasses, an original design of DCM has been developed and introduced into production. The new mold solves the following problems: it fa
