In a major leap toward self-reliance in defense technology, India is set to develop its very own fifth-generation fighter jet—the Advanced Medium Combat Aircraft (AMCA) . In a historic move, Defence Minister Rajnath Singh has approved an innovative execution model for the indigenous stealth fighter programme. This model brings together Hindustan Aeronautics Limited (HAL) and private industry players in a competitive framework, marking a significant shift in how India approaches military aviation manufacturing. This bold initiative comes at a critical time, as China has already fielded two fifth-generation fighters , and reports indicate it will supply 40 J-35 stealth jets to Pakistan . Against this backdrop, fast-tracking the AMCA has become an urgent national security imperative. AMCA: India’s Indigenous Stealth Fighter Dream The AMCA project , spearheaded by the Aeronautical Development Agency (ADA) under the Defence Research and Development Organisation (DRDO) , received its l...
Multi-Principal Element Alloy (MPEA): A Breakthrough in Fatigue Resistance Introduction Materials science has always sought to push the boundaries of strength, durability, and resilience. Traditional alloys, usually composed of one or two principal elements, have long been the foundation of industrial applications. However, a revolutionary approach in metallurgy, known as Multi-Principal Element Alloys (MPEAs), has emerged as a game-changer. Researchers at the Indian Institute of Science (IISc) Bangalore have recently developed a fatigue-resistant MPEA, challenging the long-standing belief that increasing strength compromises fatigue life. This blog delves into the significance, characteristics, applications, and groundbreaking findings related to MPEAs. Understanding Multi-Principal Element Alloys (MPEAs) MPEAs, also referred to as Compositionally Complex Alloys (CCAs), are a new class of materials designed with multiple principal elements rather than being dominated by one or two....
