“…In the presence of a given number N of observed data, the average, represented by the symbol x, is computed. The symbol "i" represents an integer value within the range of 1 to N. Standard deviation (SD) is a statistical measure employed to ascertain the proximity of data points in a statistical sample to the mean value of the dataset [13,14]. Table 1 presents the average water uncertainty analysis, while Table 2 displays the uncertainty analysis of average particle fraction.…”

“…The occurrence of fundamental physical-chemical processes on the surface of the base material is a prerequisite for getting a correctly constructed soldered joint that meets the prescribed operating requirements [5]. It is crucial to first acquire the best wettability and spread-ability of the used solders in order to enable capillary phenomena and a tight filling of the soldering gap with liquid solder [6]. As a result, the choice of solders and fluxes, two auxiliary materials for flame soldering, has a significant impact on the quality of a soldered joint [7].…”

Since hard metals are among the materials that liquid brazing alloys scarcely adhere to, they should not be brazed without first removing the surface layer after sintering. The electrolytic etching method, which gives the surfaces of materials that are hardly wettable very good energetic qualities, is given specific attention. Deep etching is done by using a high concentration of acid solution to roughen the surface. Both dry and wet settings are suitable for etching. An etching fluid is used for etching in a wet environment. Typically, the plate or metal is submerged in an etching solution, where the substance is chemically broken down. While in dry etching, the plasma’s gas phase is where the etching takes place. Due to the presence of plasma in this situation, the etching process that takes place combines chemical and physical processes. Plasma etching is another name for dry etching. Deep etching is an etching process to obtain a rougher surface. Wet deep etching requires a longer immersion time and even several immersions are required. The purpose of this study was to determine the effect of etching treatment in the brazing process of Aluminium-Mild steel for its microstructure and mechanical properties. The specimens in this study used aluminium 6000 series, mild steel, Alusol ER4043, and etching fluid. Mild steel surfaces are deep etched before brazing. Specimen manufacturing standard refers to ASTM D1002. A micro photo test was conducted to compare the surface conditions of aluminium and mild steel with and without etching treatment. The deep etching process is carried out in three variations of time, namely 20, 30, and 40 minutes. The results showed that the tensile strength increased with deep etching treatment on the surface.

“…Zhang et al (2013) investigated the compensation direction of the die faces. In general, the SF method offers the advantage of compensating the die surface in various directions, as the deformation is induced by the stresses of the reversed flow in the deformed surface (Lee et al, 2023;Riyadi et al, 2021). However, it is crucial to eliminate specific membrane stresses to prevent unstable solutions resulting from buckling phenomena during the inversion of stresses.…”

This study explores the geometrical deviations that occur in cold stamping, which are caused by the spring-back effects in elastic metals after forming. The primary aim is to introduce and assess the Combination Approach. This approach seamlessly integrates the Displacement Adjustment and Spring Forward methods for die compensation. This multi-stage process meticulously corrects dimensional errors and effectively reduces spring back through iterative processes. Using the NUMISHEET model, numerical simulations have shown a significant reduction in spring back errors, with up to a 55% reduction achieved with optimized die surfaces after five iterations. The proposed Combination Approach improves the accuracy of die design and contributes significantly to the stamping industry by incorporating established techniques within finite element software. This research broadens the scope of die compensation strategies, creating new opportunities for achieving precise die design in stamping.
