High strength and high ductility achieved in a heterogeneous lamella-structured magnesium alloy

Materials Research Letters, 2023
By introducing heterogeneous lamella-structure, we obtained a superior strength-ductility synergy in Mg-alloy associated with excellent strain-hardening ability, i.e. yield strength of ∼251 MPa, tensile strength of ∼393 MPa and elongation of ∼23%.

Effect of Fiber Reinforcement on the Tensile Strength and Ductility of Fly Ash Based Composites [PDF]

, 2023
In India, the majority of power production (73%) is generated from thermal sources, with coal-based production contributing 90% of the total installed power capacity. This reliance on coal for power production results in significant amounts of fly ash, a
