Resilience: The ability of a material to absorb energy under elastic deformation and to recover this energy upon removal of load is termed as resilience. Resilience is indicated by the area under the stress strain curve till the point of elastic limit.
Creep: It is a deformation of a material due to the constant load for a long period of time. It is time and temperature dependent property of material.
Fatigue: When a body is subjected to repeated and fluctuating load it tends to develop a characteristic behavior under which failure occurs which is referred to as fatigue.
Toughness: The ability of a material to absorb energy in plastic deformation till the point of fracture is known as toughness. Toughness is indicated by the total area under the stress strain curve up to the fracture point. Eg. Copper has higher toughness than Cast iron.
age hardening is a heat treatment technique used to increase the yield strength of malleable materials, including most structural alloys of aluminium, magnesium, nickel, titanium, and some steels and stainless steels.
Age-hardening is related with duralumin
A brass alloy consisting of copper (55%), zinc (41 - 43%) and iron (1 - 3%), with the balance consisting of various other metals.
The proportions used make the material harder and suitable for valves and bearings.
335. Aluminium bronze contains aluminium and copper in the ratio of
