An alternative, nickel-stabilized ruthenium dioxide catalyst with high activity and durability in acidic oxygen evolution reaction for water electrolysis is reported. Although the toughness of structural materials is an important indicator for preventing sudden fractures or catastrophic failures, it is still lack of knowledge in the field for the Sc/Zr-modified high-strength Al-based alloy fabricated by LPBF additive manufacturing. Engineering ceramics have a relatively lower fracture toughness despite their higher strength. A low fracture toughness value indicates that materials are undergoing brittle fractures, while high values of fracture toughness are a signal of ductility. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Fracture toughness spans over a broad number of materials, showing a variation up to four orders of magnitudes. In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing. A composite material (also called a composition material or shortened to composite, which is the common name) is a material which is produced from two or more constituent materials. 1.

Mixed mode fracture of concrete and Introduction. This value is simply called material toughness and it has units of energy per volume. Toughness is the strength with which the material opposes rupture. Fracture toughness is an essential parameter in very low fluid viscosity (water) and very low modulus formations. In materials science, fracture toughness is the critical stress intensity factor of a sharp crack where propagation of the crack suddenly becomes rapid and unlimited. A material with high strength and high ductility will have more toughness than a material with low strength and high ductility. The process for Quenched and Tempered steel starts with a normalized material at 900C. The addition of a small quantity of microfibres in hybrid fibres remarkably enhanced the toughness, fracture behaviour and ductility of foam concrete compared to the inclusion of only macrofibres (Rasheed et al., 2018; Rasheed and Prakash, 2018). This led to a considerable enhancement of compressive and flexural strength by 117% and 69.6%. If a displacement develops perpendicular to the surface, it is called a normal tensile crack or simply a crack; if a displacement develops tangentially, it is It may also be defined as the threshold of force per unit area before the material undergoes fracture [1].. Under prescribed-load boundary conditions, such crack growth will be immediately catastrophic. At these low temperatures, the yield strength is high, but the fracture strain and crack tip radius of curvature are low, leading to a low toughness. Post weld heat treatment (PWHT) is a controlled process in which a material that has been welded is reheated to a temperature below its lower critical transformation temperature, and then it is held at that temperature for a specified amount of time.
