“…The straight cylindrical-shaped studs also showed inadequate mixing and lack of coalescence with the substrate [1]. Subsequent use of tapered cylindrical studs improved the filling of crack volumes and consolidation processes in FHPP of C-Mn steel, AISI 4140 and duplex stainless steels (UNS S31803) [5][6][7][8]. The taper cylindrical studs also enhanced the rate of frictional heat generation [5,9].…”

Friction hydro-pillar processing (FHPP) is a novel technique that involves solid-state joining of an external plug onto a substrate by plastic deformation. A systematic investigation on material flow during FHPP is required but rarely reported. The present work reports a coupled theoretical and a three-dimensional X-ray computer tomography-based experimental study using a Ti-alloy as a tracer material to realise the material flow during FHPP of a AISI 4140 steel substrate. The cumulative results showed that the central portion of the plug deformed in a series of layerwise shear planes. However, the plasticised material towards the outer area of the plug flowed through the clearance between the plug and the substrate with excess volume moving out as flash.

Friction stir-based channeling is a solid-state processing encompassing the friction stir channeling (FSC) and its variants. In one manufacturing action, the FSC delivers a subsurface internal closed channel in a monolithic plate with no length limitation. The unique characteristics of theses internally closed channels produced with FSC can fit the demand from several industrial fields, namely lightweight structurally stiffened panels and applications where high power density requires highly efficient thermal management systems, such as power electronics and electric vehicles-based transportation. This first review on the FSC and its variants encompasses a systematic and comprehensive understanding on physical properties, including thermal performance and channel manufacturability applied to different engineering materials. The discussion is emphasized on working principle of channel formation, tool design, influence of process parameters, geometrical characterization, mechanical properties, hardness field and microstructural features correlated with mechanical properties. It can be summarized that novel processing of channels by FSC enhances the thermal performance compared to conventional fabrication techniques. FSC can produce complex path channels with various sizes, shapes and surface finishing. Precise control on process parameters and material flow governs the channel formation that subsequently influences thermal and mechanical performances of the channels. FSC has been applied to different range of thermal management systems and has potential for many demanding existent applications and enabling new high-performance products. From the initial FSC concept based on a shoulder-workpiece clearance, to the most recent solutions, such as the stationary shoulder FSC, and the no-tilt-angle and no-shoulder-workpiece clearance, allowing the manufacturing of large size channels, leaving the processed surface at its original quota and ready to be used. A significant leap is introduced with the Hybrid FSC enabling simultaneous welding and channeling, of similar and dissimilar metal components, and therefore, enhancing design opportunities for even more competitive solutions.

“…Este aumento da dureza é resultado de altas temperaturas associadas a deformação plástica na região da solda. Estes fatores promoveram a recristalização dinâmica dos grãos e originam uma matriz com grãos refinados, fenômeno comumente observado na aplicação do processo FHPP em diversos materiais (MEINHARDT et al, 2017).…”

Nodular cast irons are an excellent alternative in manufacturing process of axels due to their characteristics and good mechanical properties. However, the necessity of joining the axels to the gears and other components, made in carbon steel, is a great challenge. Traditional fusion welding methods applied to dissimilar ferrous materials are not deeply studied. In this context, it is well known that different materials have distinct melting points which can cause difficulty in welding, besides of defects formation from solidification. Therefore, modern joining processes such as Friction Hydro Pillar Processing (FHPP) are a great alternative. In this technology, a consumable rod is rotated against to a base material, generating the heat due to the friction, promoting materials in the plastic state and then producing the weld. Hence, this work presents a preliminary study of FHPP between the FE55006 nodular cast iron and SAE 8620 steel and evaluates the rod geometry influence on microstructure and surface stresses of the welded joints. Two rod geometries were used and two welds were further produced. The results indicated that an increase in the rod contact area promoted a lower surface stress as well as a better welded joint.
