“…Response surface method is a kind of statistical and mathematical prediction, which is used to establish the model between input and result and predict the result. When all independent variable parameters in the experiment process are measurable and controllable, the secondorder polynomial function can be used in the response surface method [32], as shown in the equation (1). To analyze the influence of various parameters and parameter interaction on the mechanical interlock of the joint, the Box-Behnken design (BBD) method was used to carry out the test design [33], the blank holder spring stiffness A, the punch diameter B, and the blank holder limit height C were selected as the influencing factors, and the interlock length Y of the joint as the target value.…”

The low strength and large protrusion of the traditional dieless clinched joint hindered its application. To improve the mechanical properties of the dieless clinched joint, a novel dieless clinching process considering the limitation of the blank holder was proposed. The finite element model of the dieless clinching process was established by DEFORM-2D, the influences of the blank holder spring stiffness, the blank holder limit height, and the punch diameter on the mechanical interlock of the joint were analyzed, and the influence laws of blank holder spring stiffness and blank holder limit height on material flow and mechanical interlock were obtained. Then, the influence of these three die parameters and their interaction on the joint interlock were analyzed using the response surface method. The results show that the blank holder displacement plays a key role in the formation of mechanical interlock in the dieless clinching process. Reasonable limit height and spring stiffness of the blank holder can control the flow direction of materials, so as to improve the mechanical interlock and the strength of dieless clinched joints. It provides a new idea for improving the dieless clinching process.

Inconel 718 alloy is a chromium-titanium-nickelbased austenitic alloy with increased strength and better resistance to carburization and oxidation at increased temperatures. This is an important and efficient alloy material for the power plants of next generation [1]. These alloys can be used in sea water, power plant applications with temperature ranges up to 900ºC. The combination of resistance and the improved mechanical property makes this alloy useful in case of various applications, such as exposure of long-term and higher temperatures in corrosive area. High temperature tubes of heat exchanger in gascooled nuclear reactors and super heater tubes are the other applications of Inconel 718 alloy [2]. In addition, EBW process is a metal fabrication technique in the presence of multi-factors and multi-objectives. *Author for correspondenceThis connection of normal metals, like aluminium, steel, and magnesium of 1mm to 6mm thickness in almost all positions can be done using this process [3]. The weld joint quality highly depends on the parameters of the input process and the control of this input process parameter acts as a basic problem to the manufacturer in obtaining increased weld quality in welded joint [4]. Highly skilled engineers or operators select the parameters depending on trial and error method in order to produce a welded joint with necessary indications, but the selection of parameters using this method was time consuming [5]. The welds are utilized to find, whether they are suitable to meet the all the required specification [6]. Many researchers have studied the effect of mechanical properties of Inconel-718 alloy material and few authors published about fabrication, solidification and characterization of these alloys. It is understood that there is lack of papers on the effect of electron beam welding parameters and with their responses of bead width and depth of penetration with quality optimization.

“…According to material feed-in methods, LAM can be divided into powder spreading type selective laser melting and powder feeding type laser melting deposition [12,13]. Laser melting deposition technology is also called laser cladding (LC), which uses a high-energy laser beam to metallurgically bond the cladding material to the substrate surface, with a small heat-affected zone (HAZ), fast cooling speed, and many other advantages [14,15]. In addition, LC can inject powder with low dilution and specific quality into the substrate to improve material performance and repair material surface defects, which has been the focus of material researchers in recent years [16][17][18].…”

In this study, single-layer and three-layer nickel-based coatings were fabricated on 316L SS by laser additive manufacturing. The phase characterization, microstructure observation, and microhardness analysis of the coatings were carried out by X-ray diffraction (XRD), scanning electron microscope (SEM), and microhardness tester. And the wear resistance of the coatings was analyzed through dry sliding friction and wear test. The results show that the cross-section microstructure of the three-layer nickel-based coating is different from that of the single-layer one under the influence of heat accumulation; the dendrite structure in the central region of the former is equiaxial dendrite, while that of the latter still remains large columnar dendrites. The existence of solid solution phase γ-(Fe, Ni) and hard phases of Ni17Si3, Cr5B3, Ni3B in the coating significantly improve the wear resistance of the coating, and the microhardness is nearly 2.5 times higher than that of the substrate. However, the average microhardness of multilayer cladding coating is about 48 HV0.2 higher than that of the single-layer cladding coating. In addition, the fine surface structure of the three-layer nickel-based coating improves the wear resistance of the coating, making this coating with the best wear resistance.
