Effects of shot sleeve filling in HPDC machine
Multidiscipline Modeling in Materials and Structures, 2019Purpose High-pressure die casting is one of the manufacturing techniques used for the rational mass production of metal parts. Due to the high velocity of the molten metal during the injection phase, the die casting of aluminum is so complex and it is almost impossible to calculate these exact performances.

Strengthening by the percolating intergranular eutectic in an HPDC Mg–Ce alloy
Materials Science and Engineering: A, 2014Dual beam FIB tomography was used to create a 3D model of the percolating intergranular (alpha-Mg)-Mg12Ce eutectic in a Mg-0.51 at% Ce alloy and its tensile deformation behaviour assessed using finite elements. The eutectic itself was modelled as a fibre reinforced composite, with the elastic constants of the Mg12Ce intermetallic determined using a ...

Trennqualität in der Chromatographie (GC, HPLC, HPDC)
Chromatographia, 1976Es werden die Grundlagen eines offensichtlich allgemeingultigen Bewertungsverfahrens in der Gas- und Flussig-Chromatographie (GC, HPLC, DC, HPDC) vorgestellt und die Schlusfolgerungen fur die Praxis diskutiert. Das Bewertungsverfahren ist einfach, es zeigt aber den ganz auserordentlich wichtigen Einflus instrumenteller und methodischer Feinheiten ...

Industrial evaluation of duplex PVD hard coatings for HPDC
Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2018During high pressure die casting (HPDC), molten metal is injected into the tool cavity where it reaches high velocities that cause substantial wear of the tool components. In order to mitigate this problem, different surface treatments are sometimes employed for high production tools.

Magnesium castings offer significant weight saving potential for many crash-relevant structures in the vehicle.Until now, proper cast magnesium design was difficult and time consuming, as reliable CAE toolswere not available. In the European funded research project NADIA, a new set of CAE tools have beendeveloped for AM60 and AM50 alloys that combine ...

Influence of Wall Stocks on Mechanical Properties of HPDC AZ91
Key Engineering Materials, 2019AZ91, as one the most popular magnesium alloys is widely employed for various engineering applications in the automotive industry. They are primarily made from high pressure die cast processes (HPDC) with different wall stocks, which affect their engineering performance. Understanding the effect of thick wall stocks on mechanical behaviors of HPDC AZ91

Simulation Analysis of HPDC Process with Automobile Part by CAE
Materials Science Forum, 2014In present casting industries, product development paradigm is shifting from traditional trial-and-error to proof-of-concept based on CAE-enabled simulation. In the new production development paradigm, CAE simulation plays an important role because it models the entire casting process and reveals the dynamic behavior of the casting system in working ...

Process-Structure-Property Correlations for HPDC AM60B
2015In this paper, we characterize the local micro structure and mechanical properties of an AM60 magnesium alloy high-pressure die-casting in order to further develop predictive process-structure-property models. The casting process is simulated using the commercial code ProCAST™ in order to extract information regarding mold-filling and local ...

Solidification Time Estimation and Simulation - In Case of HPDC
Materials Science Forum, 2010Since cast parts are used by the mankind -and the casting method should be one of the oldest metal forming technologies- the foundrymen struggle with various kind of difficulties. The most elementary ones are thermal problems during pouring. The basic condition, filling the mould before the metal solidifies to get the whole required shape, underlies ...

A microplasticity-based definition of the skin in HPDC Mg–Al alloys
Materials Science and Engineering: A, 2013The hardness profiles across the thickness of tensile specimens of alloys with a range of Al contents were used in conjunction with tensile data to determine the thickness of the strongest possible outer layer for each alloy, thus defining the casting skin.
