  Tensile and Microstructural Behaviour of Friction Stir Welded AL7050 Hybrid Composites Reinforced with Multani Mitti and Cow Dung Ash

  By Alok Kumar, Sunny Chandra, Shiv Kumar Ray, Aahish Kumar Aman, Ashish Ranjan, Md Parwez Alam, Raushan Kumar

  Abstract: The study examines Al7050 aluminum alloy composites made by stir casting and bonded by friction stir welding (FSW), supplemented with environmentally friendly Multani Mitti (MM) and cow dung ash (CDA). The study assesses the effects of different hybrid reinforcement contents (0–8 vol%) on the microstructural properties, hardness, and tensile behavior of the base alloy and its FSW joints. Tensile testing reveals an initial decline at 2% reinforcement but a notable …

  Deep Cryogenic Treatment of Copper Chill Plates in Stir Casting of Al6061-Silicon Carbide Composites

  By Alok Kumar, Shiv Kumar Ray, Rashique Arif, Sunny Chandra, Ashish Kumar Aman, Rajesh Kumar

  Abstract: Aluminum-Silicon Carbide Metal Matrix Composites (Al/SiC MMCs) represent advanced materials created through the integration of aluminum matrices with silicon carbide particle reinforcement. These composites demonstrate superior characteristics compared to conventional aluminum alloys, establishing their relevance across diverse engineering applications. This experimental investigation focuses on developing composites using aluminum as the base matrix while incorporating SiC particles (40-50μm particle size) as reinforcing agents. The reinforcement content was systematically varied from 3 …
