Biodegradable alloys, which are primarily derived from lightweight metals such as magnesium and zinc, are emerging as viable alternatives due to their reduced environmental impact during manufacturing, their potential to degrade naturally at the end of their lifecycle, and their lightweight properties which contribute to fuel efficiency in vehicles.
focusing on sustainable materials to reduce environmental impact, and biodegradable alloys have emerged as a promising alternative to traditional materials. This research investigates the optimization of hybrid extrusion-forging processes for biodegradable alloys, aiming to enhance their mechanical properties and suitability for automotive applications. The study explores the combination of extrusion and forging techniques, which are traditionally employed separately, to achieve superior material characteristics such as increased strength, durability, and formability. A series of experimental and simulation-based approaches were employed to optimize key process parameters, including temperature, pressure, and extrusion speed, for biodegradable alloys like magnesium and zinc-based materials. The findings indicate that the hybrid process significantly improves material properties, including tensile strength and elongation, compared to conventional processing methods. Furthermore, the study demonstrates that the optimized hybrid process holds great potential for automotive applications, offering a sustainable alternative without compromising performance. The results also highlight the challenges of working with biodegradable materials, including cost and processing limitations, which will need to be addressed for broader industrial adoption. This research contributes to advancing the field of green manufacturing by providing insights into the effective use of biodegradable alloys in the automotive industry.
Magnesium and zinc-based biodegradable alloys have gained attention in various sectors, including the automotive industry, because of their low density, which makes them suitable for lightweight vehicle components. Magnesium alloys, in particular, offer excellent strengthto-weight ratios, but their use in automotive applications has been hindered by challenges such as poor ductility, limited formability, and susceptibility to corrosion. While biodegradable alloys promise environmental benefits, their mechanical properties often fall short compared to more traditional materials like steel and aluminum, which are crucial for automotive components that require strength, durability, and toughness. To address these limitations, it is essential to optimize the manufacturing processes of biodegradable alloys, improving their mechanical properties without compromising their sustainability advantages. Among the most effective metal forming processes are extrusion and forging. These processes are widely used to shape and strengthen metals in various industries. Extrusion involves forcing material through a die to create components with a consistent cross-sectional profile, making it ideal for producing long, complex shapes. Forging, on the other hand, is a process that involves shaping a material by applying compressive forces, which enhances its mechanical properties, particularly strength and toughness. While both processes offer distinct advantages individually, combining them into a hybrid extrusion-forging process presents an opportunity to capitalize on the strengths of both methods, particularly for biodegradable alloys.
Keywords- Combination of extrusion and forging techniques, biodegradable alloys like magnesium and zinc-based materials etc.
1. Introduction The automotive industry has long relied on conventional materials like steel, aluminum, and other metal alloys to produce vehicles that meet performance, safety, and durability requirements. However, with the growing global emphasis on sustainability and reducing environmental footprints, there has been increasing pressure to adopt alternative materials that not only
