Abstract: Higher strength and tighter dimensional tolerance is desired for the injector nozzles to attain high injection pressures for lower NOx and particulate emissions. Cold forming is an alternate ...

Abstract: Dilute sprays are used in hot die processing to lubricate and cool the die surface prior to forming of the part. These sprays are often stochastic in nature with fine droplets that are ...

Abstract: A review of some existing criteria for diffuse necking in sheet metals is given and their limitations are discussed. The introduction into production of new sheet materials whose plastic ...

Abstract: This paper describes a new method for design optimization of process variables in multi-pass wire drawing processes. An adaptive Micro Genetic Algorithm (μGA) has been implemented for minimizing ...

Abstract: This paper presents details of a quasi three-dimensional finite element formulation for shape rolling, TASKS. This formulation uses a mix of two-dimensional finite element and slab element ...

Abstract: In the paper the continuous dynamic recrystallization (CDRX) phenomena occurring in the FSW of AA7075-T6 butt joints is investigated at the varying of the most relevant technological and geometrical ...
