Recrystallisation
Recrystallisation is a process accomplished by heating whereby deformed grains are replaced by a new set of grains that nucleate and grow until the original grains have been entirely consumed.…
Stress relieving
Stress relieving is carried out on metal products in order to minimise residual stresses in the structure thereby reducing the risk of dimensional changes during further manufacturing or final use…
Benefits of Air-entrained Concrete
Air entrained concrete has microscopic air bubbles in the concrete. Air bubbles provide durability for concrete exposed to freezing and thawing. These air bubbles help to improve the workability of…
Types of Annealing
Annealing is a process by which the properties of steel are enhanced to meet machinability requirements. Annealing is a process of heating the steel slightly above the critical temperature of…
What Are The Properties Of Air Entrained Concrete?
Air entrained concrete A major advance in concrete technology in recent years is the introduction of tiny disconnected air bubbles into concrete called air entrainment. Air entrained concrete results from…
