Brittleness is a quality of a solid which cannot be considered apart from fracture, because fracture is always implied. A material is described as brittle when it breaks while undergoing elastic deformation. Very few industrially useful metals fall into this category; most exhibit some degree of ductility, the antithesis of brittleness. Yet, as will be demonstrated, a metal may deform plastically and break in a brittle manner. Brittleness is not a specific property of any solid, nor is a low temperature the only factor which may cause a ductile metal to break in a brittle manner. While an endeavour has been made to limit the scope of this review to a discussion of the effect of atmospheric and subzero temperatures upon brittleness, it is neither possible nor desirable to exclude reference to other known causes. Absence of ductility, due to composition, heat-treatment, previous cold work, &c., can usually be detected by well-established mechanical tests. A phase or allotropic change, or precipitation, which takes place at low temperatures and produces permanent changes in structure and physical and mechanical properties can be controlled by the same methods. Brittleness which manifests itself only under certain conditions of stress and temperature must be investigated by special methods of testing. Moreover, unlike the more usual forms of brittleness just enumerated, it is transient; it disappears when the temperature is raised.
Stainless steel is not considered brittle, as it is known for its strength and durability.
A brittle alloy is a type of metal that lacks the ability to deform plastically before fracturing. This means it is prone to breaking or shattering easily under applied stress, rather than bending or stretching. Common examples of brittle alloys include some types of cast iron and certain high-carbon steels.
One common metal that fits this description is iron. Iron is a hard and brittle metal with a gray color when in its pure form.
Phosphorus is not naturally occurring in its pure form; it is typically found in compounds. The most common form of phosphorus is white phosphorus, which is waxy and can be easily broken into pieces. However, red phosphorus is more stable and less brittle.
HC steel, or High Carbon steel, is a type of steel that contains higher amounts of carbon compared to other types of steel. This makes it harder and more durable, but also more brittle. HC steel is often used in tools and cutting implements where strength and hardness are important.
Stainless steel is not considered brittle, as it is known for its strength and durability.
brittle
it is ductile. For hardened stainless steel it gets less ductile, but not brittle.
more brittle
Yes
It will be lowered with the result that the steel becomes more brittle.
Because hard steel would be brittle and break.
Carbon Steel - Martensite
Cast iron is more brittle then mild steel
You heat treat to improve the molecular structure of the steel. In the untreated state steel is very soft and is relatively easy to bend but when hardened the steel become very hard and brittle. The steel is so brittle after hardening that if say dropped on a concrete floor it may shatter. Tempering relieves some of this stress and makes the steel hard but not too hard.
When steel gets cold, it contracts and becomes more brittle. At extreme cold temperatures, it can become susceptible to fracturing or shattering. This is why structural engineers and material scientists consider the impact of low temperatures on steel when designing structures and equipment.
Yes, liquid nitrogen can be used to cut steel. When liquid nitrogen is applied to steel, it causes the steel to become extremely brittle and easier to break or cut. This method is often used in industrial applications for precision cutting of steel components.
