Modeling the heat treatment of ausferritic ductile iron

Ausferritic ductile iron (ADI) combines the freedom of the molding style of cast iron with the strengths of steel. ADI forms by heat treatment of nodular cast iron. To take full advantage of the technical potential of this material, extensive controls of the casting and the heat treatment processes are required. The authors describe an integrated approach of experimental studies and modelling for optimum process design. The simulation tools developed permit exact predictions of the microstructure due to the heat treatment. If certain suitable technical parameters are observed, an ausferritic microstructure without pearlite, martensite and bainite can be obtained. The parts produced had very good reproducible mechanical properties distinctly better than the applicable limits

Pialorsi Stampi: The innovation of the Polini electric motor guaranteed by high-performance die-casting with QuickCast and ProCast

19/01/2024

Success stories

QuickCast and ProCast are the predictive software tools used by Pialorsi Stampi in the creation of an electric motor for e-bikes for Polini Motori. The product and process simulations offered by both software tools made it possible to transform an ambitious and innovative project for the construction of aluminium supports to connect the electric motor to the bike frame into reality.
The aim of the project was to make two non-porous parts using an alloy with sufficient mechanical properties to withstand the stresses of off-road use.
The technical challenge during the production phase was to create the best conditions for the welding and subsequent heat treatment of the components.
QuickCast and ProCast software were used to simulate three different possible settings for the mould with a view to choosing the most functional solution. The results of the simulations were gradually analysed and the right adjustments made it possible to eliminate any flaws highlighted by the predictive programmes during the design phase, resulting in a functioning end product with all the specifications required by the customer.

Shot Peening Modeling in DEFORM

28/04/2023

Technical papers

SFTC recently took part in a research project to develop modeling methods for shot peening processes. A deliverable from this work was the new Shot Peening Template, which streamlines the setup and simulation of this complicated process.
Shot peening is a beneficial surface treatment used in a wide range of industries. It induces a compressive residual stress on the surface of a metal component via cold working. This is accomplished by firing spherical shot onto a part at high velocity. The resulting compressive stress state counteracts tensile stresses experienced during inservice operation. This can greatly increase a part’s fatigue resistance.

Orbital Forming Assembly – Software DEFORM

06/12/2021

Success stories

Simulation has shown that the orbital forming assembly process can benefit from a decreased feed per revolution. Decreased forming contact area requires a smaller forming load and press size. The flange provides a greater restraining force because the springback is reduced when the forming tool is removed.
However, if the feed rate becomes too low, inward material flow can occur which is undesirable. In this case, the v2 feed profile will be used because it provides the lowest feed rate at the end of the stroke without producing a defect.

The materials and the design of the die in a critical manufacturing step of an automotive shock absorber cap

03/12/2021

Technical papers

The industrial drawing of automotive shock absorber endcaps caused wear and radial brittle fractures of the tool steel dies. A finite element method (FEM) simulation of the process showed that this was caused by high contact and hoop stresses on the die. Such difficulties are usually solved by expensive changes in the die material, but a change in the punch design was proposed as a simpler and cheaper solution. The new punch geometries were employed in a FEM simulation of the drawing, indicating much lower contact and hoop stresses. The implementation of the solution eliminated the wear and brittle fracture problems.

The simulation software for casting, forging, rolling, heat treatment and machining allow to expand or compress it: ingots of tons that take days, to give just one example, can be reduced and evaluated in a few minutes; conversely, steps of a few thousandths can be analyzed in hundreds of seconds. But the time factor today is also the key to the diffusion process of these virtualization programs of the production cycle. "It's only a matter of time: even in the world of steel, the tools that allow the virtual reality of production processes will be widespread."
