Abstract

This article reviews the fabrication methods of metal matrix composites (MMCs) in liquid state. Metal matrix composites, especially aluminium metal matrix composites (AMMCs), are widely used in automotive, aviation, and medical industries due to their superior properties such as low density, good wear resistance, and specific strength. Liquid-based manufacturing processes include infiltration, stir casting, centrifugal casting, squeeze casting, vacuum die-casting, compocasting, and rheocasting. Each method offers specific advantages in reinforcement distribution, cost efficiency, and complex shape manufacturability. Infiltration is effective in achieving good interfacial bonding; stir casting is popular because it is simple and economical for mass production; centrifugal casting excels in forming high-density and wear-resistant composites; squeeze casting and vacuum die casting increase the strength and density of composites; while compocasting and rheocasting offer more homogeneous microstructure and grain refinement. This review shows that the selection of method should be based on the specific application requirements and material characteristics to achieve optimum mechanical properties. With improvements in technology and control of process parameters, liquid casting methods offer significant potential for the manufacture of high-performance structural and functional components.

Abstract

The modern industrial era is characterized by the high complexity of systems and the demand for operational efficiency, making maintenance systems play a crucial role in ensuring reliability, safety, and sustainability of production processes. Reliability-Centered Maintenance (RCM) has emerged as a strategic approach to replace conventional Preventive Maintenance (PM) methods, which are often static and inefficient. This study compares the effectiveness of RCM and PM in terms of maintenance cost and risk through a literature review across various industrial sectors, including power generation, automotive, maritime, food and beverage, and energy distribution systems. The results show that RCM implementation can reduce unplanned downtime by up to 55.77%, increase system reliability by 28%, lower maintenance costs from 20% to 70%, and raise system availability from 57% to over 90% in some cases. RCM has also proven to be more adaptive to actual equipment conditions, supports risk-based decision-making, and is more effective in scheduling maintenance for critical assets. Although its implementation requires more data resources and technical expertise, RCM demonstrates superior long-term performance. This study recommends the integration of a hybrid strategy that combines the strengths of RCM, PM, and predictive approaches powered by digital technologies to comprehensively enhance the efficiency and reliability of maintenance systems.

Abstract

Post-Weld Heat Treatment (PWHT) is a widely employed thermal method used to relieve residual stresses and enhance the mechanical properties of welded joints. This study investigates the effect of PWHT on the mechanical and microstructural properties of SS400 steel welded using the Gas Metal Arc Welding (GMAW) process. The research focuses on evaluating how variations in PWHT temperature influence tensile strength. impact toughness. hardness. and microstructural characteristics. Specimens were subjected to PWHT for 1 hour with a 15-minute holding time. followed by natural cooling at room temperature. The results indicate that PWHT significantly improves impact toughness and refines grain structure. especially in the Heat Affected Zone (HAZ). while leading to a reduction in tensile strength compared to untreated specimens. Higher PWHT temperatures promoted the formation of finer ferrite and bainitic phases. contributing to enhanced ductility and toughness but reduced hardness due to grain coarsening. Microstructural analysis confirmed a shift in phase composition. where an increased ferrite content resulted in lower hardness. while a dominant pearlite phase corresponded with higher hardness values. Overall. this study highlights the importance of optimizing PWHT parameters to achieve a desirable balance between strength. hardness. and toughness in SS400 welded joints. particularly for structural applications such as shipbuilding.

Abstract

Surface quality of machined parts is an important indicator in determining the final performance of engineering components. One of the main factors influencing this parameter is the type of coolant used during the cutting process. This study is a literature review aimed at systematically comparing the effects of synthetic, mineral, and vegetable-based coolants on surface roughness in various machining processes such as turning, milling, and drilling. The literature review method involved searching reputable scientific articles indexed in Scopus, with a focus on quantitative surface roughness data (Ra). The analysis results showed that plant-based coolants provided the best performance, with a reduction in Ra values of up to 55% compared to conventional mineral coolants. Meanwhile, synthetic coolants demonstrated high cooling capabilities but their lubricating properties remained below those of plant-based coolants. Mineral fluids were found to have the lowest performance in terms of surface quality and environmental impact. This study confirms that the use of plant-based fluids, particularly in Minimum Quantity Lubrication (MQL) systems, is a promising solution for achieving efficient, sustainable, and environmentally friendly machining processes.

Abstract

Noise control is a growing concern in built environments, vehicles, and industrial machines. Porous multi-layer composite materials are currently the most used for this purpose. Some of them are felt-based materials widely utilized in acoustic applications due to their excellent sound absorption properties, flexibility, lightweight nature, and low manufacturing cost. Some synthetics & hybrid fiber materials are widely used for acoustic purposes. To optimize the acoustic performance, one of the materials, such as resinated felt, is commonly combined with nano-porous materials like spunbond, a PET-based non-woven material, as a skin layer due to their adjustable fiber structure and cost-effectiveness. Bonding compression techniques—including hot pressing, thermal bonding with low-melting fibers, and skin lamination spunbond are crucial in fabricating multi-layer acoustic composites from porous materials. This review synthesizes findings from studies detailing process parameters, material choices, and how compression affects porosity, fiber entanglement, and inter-layer bonding to optimize sound absorption. Special attention is given to the effects of processing parameters on porosity, air permeability, and fiber orientation—factors that critically influence acoustic behavior. Challenges such as frequency-dependent performance loss and scalability limits are discussed. Future research should target the development of the cycle optimization process and real durability evaluation.

Abstract

One of the most suitable methods for mass production of complicated shapes is injection molding due to its superior production speed and quality. Plastic injection is the process of forming products from plastic materials with variations in shape and size. Controlling the quality of plastic products is an important aspect of the plastic injection molding process. To achieve high process effectiveness and desired product quality, correct and precise parameter settings are essential. One of the benchmarks for assessing the productivity and efficiency of an industry is to look at the level of product defects that occur in producing a product. This article aims to provide a brief review of the explanation of injection molding, types of molding, types of injection failure, experimental methods in determining injection molding parameters. Types of failure in the injection process such as short shot, weld mark, warpage, sink mark, air trap, black spot, flashing, hole, over molding, delamination. The experimental method determines parameters such as the Taguchi method, ANOVA method, hard computing techniques. The future will likely tend to use AI techniques as has happened with other methods in manufacturing processes to complement conventional techniques in determining injection molding process parameters.
