“…To distinguish these from the composite material, each of these two bonded materials making the composite is called a "phase" in what follows, even though these might, by themselves, be multiphased. Here, practical implications of the analysis are examined, to probe how it can aid the design of ductile Laminated Metal Composites (LMCs), originally reviewed by Sherby, Wadsworth et al [6,7], more recent reviews being in Refs. [8,9,10].…”

This contribution draws practical implications of a recently published estimation of the tensile ductility in laminated composites made of two ductile materials, typically metals or alloys, which harden as both the strain and the strain-rate increase. To this end, the literature is surveyed to collect values for the strain hardening exponent, the strain-rate sensitivity and the strength constant for a wide range of engineering metals and alloys. Material combinations that might produce ductile laminated metal composites are then examined in light of the data and theory. A simple graph is proposed, which gives a direct reading of the predicted elongation to failure of composites containing equal volume fractions of any two materials among those surveyed. The resulting plots show material combinations in which a more ductile material can significantly increase, within a Laminated Metal Composite (LMC), the tensile elongation of a less ductile material. In this role, 304 stainless steel and commercial purity iron emerge as sensible possibilities.

“…Laminated metal composites (LMCs) have drawn considerable research attention over the past two decades due to their unique properties including advanced mechanical performance and virtuous complementarity between the constituent metals [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] . Fabrication of materials in the form of laminated structure with immaculate interfacial bond can significantly improve many properties such as fracture toughness, impact resistance, fatigue behaviour and damping capacity; or provide enhanced ductility or formability for otherwise brittle material [1,2] .…”

Based on the advantages, increasing efforts have been focused on improving the workability of the brittle metal or alloy by means of lamination with the ductile material [5,6] .…”

Journal of Iron and Steel Research International, 22 (5), 438-445. Interface analysis and hot deformation behaviour of a novel laminated composite with high-Cr cast iron and low carbon steel prepared by hot compression bonding AbstractA hot compression bonding process was developed to prepare a novel laminated composite consisting of highCr cast iron (HCCI) as the inner layer and low carbon steel (LCS) as the outer layers on a Gleeble 3500 thermomechanical simulator at a temperature of 950 °C and a strain rate of 0.001 S -1 . Interfacial bond quality and hot deformation behaviour of the laminate were studied by microstructural characterisation and mechanical tests. Experimental results show that the metallurgical bond between the constituent metals was achieved under the proposed bonding conditions without discernible defects and the formation of interlayer or intermetallic layer along the interface. The interfacial bond quality is excellent since no deterioration occurred around the interface which was deformed by Vickers indentation and compression test at room temperature with parallel loading to the interface. After well cladding by the LCS, the brittle HCCI can be severely deformed (about 57 % of reduction) at high temperature with crack-free. This significant improvement should be attributed to the decrease of crack sensitivity due to stress relief by soft claddings and enhanced flow property of the HCCI by simultaneous deformation with the LCS.

“…The history of several types of iron used in Keris [7] is still in infancy and normally described through the eyes of ancient blacksmiths. In ancient times, blacksmiths were considered among the elite occupations and assumed to be a principal contributors in creating early concepts [8] of understanding the behavior of metals, particularly iron.…”

“…One of the most attractive characteristics of the blade is the watermark pattern called pamor as shown in Fig. 2, which represents the characteristic deformation pattern on the blade [6,7]. In recent reviews [7,9] ancient Keris blade consists of alternating metals that bonded at the interfaces.…”

The traditional steps in the fabrication of Malay Keris blades which are preserved in traditional knowledge are explained in consistency with the modern metallurgical engineering. These are forging, quenching, tempering and etching. The material selection process for specic parts of the blade is discussed and correlated to the particular fabrication method used to produce the nal properties, which consist of the ductility, hardness and the watermark pattern on the blade. Morphologies of the microstructure are also in agreement with the observed properties in which the central strip of the blades possesses some ductility to facilitate forging whereas the harder edge area is made of steel with higher carbon content
