Dual–Phase Hot–Press Forming Alloy
Hot–press forming steels are formed in a fully austenitic state followed by die– quenching in order to generate martensite and achieve a strong steel. The ductility however, tends to be limited. We explore in this work a novel steel design in which the forming operation is in the two–phase austenite and ferrite field, so that the quenching results in a dual–phase ferrite and martensite microstr...

متن کاملEvaluation of Ductile Damage Criteria in Hot Forming Processes
The process of ductile fracture which occurs due to the accumulation, growth and combination of defects or cracks of material is called ductile damage. Failure in materials can be predicted, using damage mechanics and damage criteria. On the other hand, most of the materials depended to the manufacturing process, are formed in warm or hot conditions so that; the temperature also affects on the ...
متن کاملInvestigation of hot metal gas forming process of square parts
Aluminum alloys are considered a lot in the automotive and aerospace industry because of their high strength to weight ratio. In this manuscript, the gas forming process of aluminum AA6063 tubes at high temperatures up to 500°C is investigated, through experimental and numerical tests. Therefore, an experimental setup is prepared and so, tube specimens are formed in a die with square cross sect...
متن کاملMetered Size Press Coating Formulation Design for Fiber Reduction
A major driving force in paper technology development is the reduction in cost of paper production. A primary material cost in the paper production process is wood fiber, the cost of which is increasing rapidly. Reducing fiber usage is difficult, as paper properties are tightly coupled to the amount of fiber. Advances in coating formulation design have begun to show how coatings may be designed...
