In any metal forming process, both the strain rate and deformation rate depend on the die profile. The die profile also, is responsible for the non-uniformity of the deformation along the cross-section. These affect the quality and mechanical properties of the product. Therefore, if a die is designed, in which the affecting variables can be controlled spontaneously it is hoped to obtain a produ...

Abstract A new steel chemical composition is combined with a press hardening process, in which die-quenching interrupted by opening the forming tool to permit slow cooling of hot formed part through anisothermal bainitic ferrite transformation. This promotes carbon partitioning austenite before re-closed and resumed near-ambient temperature. The final microstructure predominantly dispersions ma...

Hot die forging is a forming method widely used in the automobile industry, shipbuilding, and aerospace industry. In hot process of aluminum alloy, “mold sticking” defect often occurs results low productivity short life. Herein, we prepared TiB2 reinforced nickel-based coatings by combined use plasma transferred arc melt injection method, investigated morphology properties composite conditions....
