Complex unloading behavior: Nature of the deformation and its consistent constitutive representation

The effect of the strength ratio extracted from an Archard model for wear is used to describe the wear rates expected in hot forging dies. In the current study, the strength ratio is the strength of the hot forging die to the strength of the work piece. Three hot forging die steels are evaluated. The three die steels are FX, 2714, and WF. To determine the strength of the forging die, a continuous function has been developed that describes the yield strength of three die steels for temperatures from 600 to 700 °C and for times up to 20 h (i.e., tempering times of up to 20 h). The work piece material is assumed to be AISI 1045. Based on the analysis, the wear resistance of WF should be superior and FX should be slightly better than 2714. Decreasing the forging temperature increases the strength ratio, because the strength of the die surface increases faster than the flow strength of AISI 1045. The increase in the strength ratio indicates a decrease in the expected wear rate.

Experimental Analysis on the Frictional Behaviour of Drawbeads in Sheet Metal Forming

The basic properties of materials play a dominant role in their processing. It is important not only to obtain quantitative values for the behavioral properties of a given material during a process, but also to understand how the properties were measured. The goal of this volume of the work is to provide pertinent information on how some important material properties are measured, as well as to provide a degree of insight into some developing (i.e., specialized) materials so that manufacturing engineers can begin to meet the challenges of industrial production by taking advantage of the unique properties for these emerging materials.

The fabrication of Ti5Si3 in the form of a solid product directly from an elemental 37.5 at.% Si and 62.5 at.% Ti powder mixture was carried out by two different powder metallurgy routes. The first was by uniaxial pressing of the reactant powder mixture with sequent vacuum-sintering, and the second was by electric discharge sintering (EDS) of reactant powder mixture. The pressing process combined with vacuum-sintering produced a porous compact with multi phases of titanium silicide such as Ti5Si3, Ti5Si4, TiSi2, and TiSi, including elemental Ti, which indicated an incomplete phase transformation into Ti5Si3. On the other hand, the EDS induced the phase transformation mostly into Ti5Si3 with a small amount of Ti5Si4 in
