“…The NSF process still needs much more experimentation and research to completely understand and define the processing limits in terms of material and processing conditions. In any case, what is clear is that the NSF process is capable of achieving sound components of very complex shapes requiring low forming loads and, as assessed in previous works [ 14 , 15 , 16 ], as forged mechanical properties whilst reducing the component cost compared to the hot forged one by around a 10–15%.…”

“…For the very first trial, the conditions at which sound components were attained in the past with other geometries were used [ 14 ]. Therefore, a forging temperature of 1360 °C was used with an initial billet size of 70 mm of diameter and 90 mm height.…”

“…This material was one of the first materials used in NSF obtaining great results and, hence, its forming conditions are better defined than with other materials. Moreover, this steel ensures the attainment of as-forged properties after the post-processing quenching and tempering heat treatment as stated in [ 14 ]. The following table ( Table 1 ) shows the chemical composition of the alloy.…”

“…These problems have been proposed to be addressed through using Near Solidus Forging (NSF) technology. Previous works assessed how the manufacturing of large batches of components without observing any severe die damage has been possible, attaining as-forged properties [ 14 , 15 , 16 ], using off-the-shelf alloys and reducing by nearly 10 times the force required to fabricate the component by conventional hot forging [ 17 ]. This mainly comes from the optimization of the working conditions and equipment.…”

The benefits of the novel Near Solidus Forming (NSF) process has shown previously in its ability to produce steel components with comparable as-forged mechanical properties but with a cost reduction of 10–15%. This study further pushes the NSF technology to produce parts that are conventionally difficult to produce via conventional methods. A 2.7 kg 42CrMo4 steel grade component was manufactured into a complex geometry using only a 400t press. Different manufacturing parameters were evaluated to show their influence on the process and final component. A combination of X-ray fluorescence (XRF), optical microscopy and SEM analysis of the microstructure was also conducted revealing the deformation pattern of the material and shedding some light on how the material evolves during the process. The successful forging of these components shows the capability to produce previously deemed difficult geometries, with much a lower specification forging press, in a single deformation.

“…In any case, great developments have been made in recent years. To date, some off-the-shelf low [8], medium [9,10] and high [11] carbon steel alloys have been successfully manufactured by SSF. Moreover, the tool wear, one of the main problems of this technology, does not seem to be so critical as more than 6000 components have been manufactured without any discernible tooling damage by Bigot et al [12].…”

Nowadays, globalisation enables a rapid uptake of the classical manufacturing technologies. In order to remain competitive and fulfil the global trend of reduction of emissions, innovative production processes that reduce the energy and raw material consumption should arise. Semisolid forging (SSF) is one of those techniques with great potential to fulfil those requirements maintaining the high quality of the components. Thus, the objective of this work is twofold: to produce a complex geometry part saving material and energy using the off-the-shelf S48C steel grade, and to demonstrate the capability of the process to produce a pre-series of 250 components without excessive tooling damage.
