Finite Element Simulation of Hot Forging

FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization

Hot forging comprises all forming processes that occur above the recrystallization temperature of a metal. The characteristic effect of hot forming, is the significant material strength reduction (yield stress). Hot forging is used when the goal is to achieve complex 3D geometries via forming. In addition, it enables the processing of difficult-to-form materials, which can be formed only with limitations when cold. Due to the strength reduction under hot forging conditions, the force and work demand of the processes can be lowered in comparison to cold forming.

The recrystallization is responsible, through the complete reformation of the microstructure, possibly multiple times, for the formation of a relatively fine-grained microstructure. It exhibits the optimal combination of strength and ductility. This circumstance qualifies hot forging as one of the most important manufacturing processes for the production of highly stressed safety components.

Using advanced Metal Forming Simulation methodology and FEA tools such as Ansys, Simufact Forming, Autoform, FTI Forming, Ls-dyna and Abaqus for any bulk material forming deformation, combining with experience and development have made Enteknograte the most reliable consultant partner for large material deformation simulation.

Phase Transformation and Thermal Effect in Metal Forming

Including phase transformation and thermal effect enables us to realistically simulate the hot forming processes. These processes have become very important for the automotive industry in order to meet specific requirements regarding a higher level of crash safety and a reduction of overall weight. Detailed simulation of forming enable us to engineer components with high strength, challenging geometrical complexity and minimized springback effects. In addition, we can calculate the final part properties, such as strain-stress distributions as well as the distribution and local percentages of different material phases, such as austenite, ferrite, pearlite, bainite and martensite, including the resulting hardness distribution.

Springback Compensation

Springback compensation is carried out during the process engineering phase to improve part and tool quality before the real tryout phase begins. As a result, the process layouts realized during the early planning phases are more reliable. Robust springback compensation enables us to minimize the risk of costly changes later on in the process due to the effects of springback.

Sheet Metal Forming: Advanced Finite Element Method for Industry Leading Simulation

Sheet metal components are highly suited to lightweight constructions. Different methods of sheet metal forming can be used depending on the geometry of the desired part. Based on the characteristics of each deformation process, the forming engineer can choose between: Deep drawing, ironing, punching, bending, stamping, and a variety of other manufacturing processes. Due to the geometric complexity of the parts being manufactured, additional multistage forming that combines different processes is frequently required within a phase of production.

Finite Element Simulation of Hot Forging

The recrystallization is responsible, through the complete reformation of the microstructure, possibly multiple times, for the formation of a relatively fine-grained microstructure. It exhibits the optimal combination of strength and ductility. This circumstance qualifies hot forging as one of the most important manufacturing processes for the production of highly stressed safety components.

Metal Forming Process: Open Die Forging Finite Element Simulation

When designing open die forging processes, the pass schedule, including possible intermediate heating, must be planned in such a way as to reach the required final geometry and the required material properties with as little effort as possible. High performance materials such as titanium and nickel based alloys can only be forged within a narrow temperature range.

Cold Forming Finite Element Simulation

Cold forming results in strain hardening, meaning both the strength and resistance to forming increase with ongoing deformation. Thus, cold formed components can withstand greater operational loads. At the same time, strain hardening results in reduced formability (ductility) of the material. If the component needs to be formed further, the strain hardening of the component has to be removed via recrystallization annealing. Cold forming and annealing are often part of a multi-stage process.

Finite Element Simulation of Roll Forming and Ring Rolling

Rolling is one of the most diverse forming processe in the forming technology. It is used for the production of semi-finished as well as finished products. Rolling processes are used in all areas of forming technology, both in hot forging and cold forming, and of course in sheet metal forming. There is a multitude of rolling processes. Some are named here: flat rolling, profile rolling, tube rolling, roll forming, forge rolling, cross-wedge rolling, wire rolling, and cross-row rolling.

Finite Element Simulation of Heat Treatment

In principle, there are two kinds of heat treatment processes: processes resulting in a thorough change of the microstructure and processes that result in merely changing regions close to the surface of the component. Examples of the former would be thermal processes, such as annealing and hardening. Examples of the latter, thermochemical processes, would be diffusion and coating processes, such as carburization, case hardening, nitrating, boriding.

Hard Metal: Finite Element Simulation for Mechanical Properties on the Microstructural Level

Hard metals are functional materials with tuned performances arising from the composite microstructure. Understanding those composites on the microstructural level is key for material suppliers who need to innovate their products. Hard metals are two-phase materials with significantly differing mechanical properties on the microstructural level. Material properties are tuned by varying the content and microstructure of a hard inclusion phase. Key to further material development is to understand and optimize microstructural stresses in the composite.
