Antimatter consists of particles with opposite charge and magnetic moment to matter. Positrons have positive charge, antiprotons have negative charge. Matter and antimatter annihilate each other, releasing gamma rays
Journal covers Metallurgy, Composite materials, Crystallography, Alloy and Thermodynamics. Metallurgy research includes Microstructure, Creep, Aluminium and Grain boundary. Composite materials study links with Forensic engineering and Mechanics. Crystallography combines with Condensed matter physics and Analytical chemistry
Brittle materials fracture with little elastic deformation and significant plastic deformation. Breaking often produces sharp snapping sound. Broken halves should fit exactly due to no plastic deformation
Stress-strain curve shows relationship between stress and strain in materials. Curves can represent any deformation type, including compression and stretching. Typical stress-strain curve refers to axial normal stress-strain in tension tests
Betrayal is breaking presumptive contracts or trust in relationships. Betrayers are commonly known as traitors or betrayers. No clear definition exists, but betrayal is better understood through literature
Textbook provides historical perspective and basic concepts of materials science. Covers classification, advanced materials, and modern material needs. Includes references and questions for further study
