Microstructural Properties of Semisolid Welded Joints for AISI D2 Tool Steel

Abstract

The aim of this study is to investigate experimentally the microstructural evolution of the joints using ledeburitic AISI

Flow Behavior of 1.4841 Steel in Hot Compression Process

“…In fact, if the temperature increases, activation of atoms will grow. So, subgrain boundary and anile twins can act as main centers of recrystallization nucleation formation and can quickly be formed to accelerate dynamic recrystallization (Mohammed et al 2014). Temperature sensitivity parameter (η a ) expresses temperature effect on steels when strain and strain rate is constant.…”

Trend and Development of Semisolid Metal Joining Processing

“…Furthermore, a smooth transition from one part to the other is obtained with no evidence of microcracking or porosity. As for the interfacial reactions that occurred during the heating process, these provided elemental diffusion across the interface and the eutectic liquid spread between the joined surfaces to achieve what appears to be good join at the interfaces of both parts of the steel [38,39]. On the other hand, a study of D2-304 joining revealed that a new type of nonequilibrium diffusion interfacial structure was created at the interface of the two different types of steel [40].…”

“…In addition, this joining process allows surface-tosurface joining rather than the line-to-line joining of conventional welding. Therefore, it prevents corrosion at the interface of the components and confers Tool steel [14] Stainless steel Aluminum alloy [15] Aluminum alloy, cast iron, or stainless steel Particles, balls, short fibers of metallic or nonmetallic materials, such as ceramic, glass, tile, or stone, aluminum alloy, copper alloy, or stainless steel [5,12,17,18] Stainless steel M2 tool steel [20] X210CrW12, 100Cr6, and X5CrNil18-10 9SMn28, CuCo2Be, CuSn12, and GBZ12 [13,21] Sn-15 wt%Pb Sn-15 wt%Pb Sn-5 wt%Pb [10] Pb-15 wt%Sn Pb-15 wt%Sn [25] Zinc AG40A die cast alloy Zinc AG40A die cast alloy [26] A356 A356 [27] SiCP/A356 composites 2024 aluminum alloy Zn-Al [29] SiCP/A356 composites SiCP/A356 composites Zn-Al [43] AZ91 alloy AZ91 alloy Mg-25 wt%Zn [33] A356 aluminum alloy A356 aluminum alloy [34] D2 tool steel D2 tool steel [39] D2 tool steel 304 stainless steel [40] D2 tool steel M2 tool steel [42] a better shape than welding. Furthermore, SSMJ can be used to embed metallic or ceramic materials for use in reinforcement or as bearing systems [12].…”

“…For instance, parts made of copper-based alloys, which have a lower solidus, can be inserted into a higher-solidus base material such as steel alloys. This advantage is especially important for temperature-sensitive materials whose microstructures can be damaged by too much thermal energy input and therefore need to be joined at lower temperatures [10,39].…”

“…Future efforts in this direction could include the application of this technology to alloys of commercial interest with higher liquidus temperatures and better structural qualities, such as ferrous alloys or aluminium alloys including those studied theoretically in [39]. Further work is also required to apply this technology by using an induction heating coil in a butt-joint to create a localized semisolid pool to determine the best method for the DPRM technique.…”
