Purpose of Heat treatment in carbon steel?
Generally used to improve the properties of the metal. For example to make it tougher or harder. Metals that have been cold worked will have areas of built up stress, which will waken the metal. Heat treatment can be used to remove the weak areas. Which heat treament is used depends on the desired properties of the final metal. Some examples are : Annealing Normalizing Quench Hardening Case hardening
Can you reduce the heat treatment time in carbon steel through normalizing instead of annealing?
can we reduce the heat treatment time in carbon steel through normalizing instead of annealing?
What is the specific heat of sinter?
Specific heat of sinter
What is the difference between flame and heat?
"Flame" is the visible energy when burning something. "Heat" is given off a flame and countless other things. Flame produces heat, but heat does not always generate from flame, and heat almost never produces flame (friction might count). And if you want the definitions: HEAT: a form of energy that is transferred by a difference in temperature. FLAME: the process of combustion of materials producing heat and light and (often) smoke. If you want to think of it a different way: Flame is what you see when you look at a fire and heat if what you feel from the fire.
What does a heat sink do?
A heat sink is usually something that draws something away from an electrical componet (Ex: ICU's, Processors and transistors) APEX- A device that absorbs and draws heat from a hot object, dispersing it into the surroundings.
What are the benefits of heat treatment of steels?
In short, heat treating is used to achieve the desired properties of the alloy such as hardening or softening. There are multiple methods used to do this, annealing, quenching, and tempering are a few.
Which steels are used in heat treatment and its components?
stainless steel

Annealing of steels is done to?
Steel is annealed to bring it to a specific level of hardness, reducing its brittleness after heat treatment or forging.

What is 'carburising' why and how it is done?
Carburizing is a method of hardening iron or steel by a heat treatment that causes it to absorb carbon liberated from a carbon bearing material, such as charcoal or carbon monoxide.
Does heat increase or reduce the malleability of steels?
Heat makes metal more malleable.
Is it possible to get effective case depth size 1.2 mm in mild steel material during heat treatment?
Not possible...the maximum hardness MS can have is 0.03mm by flame hardening...

Explain about the Tool Steels?
Tool Steel is a specific type of high quality steel made specifically for the production of tools and tooling components. Tool steels are produced in electric melt furnaces and stringent quality standards are upheld to produce the necessary quality. Tool steels are formulated to withstand high pressures and abrasive materials. Typically tool steels are used for shearing, cutting, stamping, and forming of metals and plastics. Example applications include compacting of powder metal into a gear form, slitting of steel coils into strips, stamping of computer parts from metal sheets, extrusion of plastic or vinyl into window frames and formation of cutting tools from high-speed tool steels. Tool steels are supplied in the annealed or soft condition, so that they may be machined and fabricated into a tooling component. These steels are designed to be used in the hardened condition, so after they have been fabricated into a tool, they must be heat treated to obtain the desired properties. The properties that tool steels provide are hardness, toughness, wear resistance and red hardness. For a further explanation of these properties, see our article Properties of Tool Steels. These properties are provided in varying degrees from a wide selection of tool steel grades. These grades fall into three basic classes of tool steels. These classes are cold work tool steels, hot work tool steels and high-speed tool steels. These classes are also divided into sub-classes. Cold work tool steels are generally divided into Water-hardening, Oil-hardening, Air-hardening, Shock-resistant and special purpose tool steels. High-speed tool steels contain high levels of cobalt, tungten and/or molybdenum and are designed to be used at elevated temperatures while still providing a high level of hardness and wear resistance to facilitate cutting of metals. High-speed steels are sub-divided into tungsten and molybdenum sub-classes. Tool steels usually contain from 0.5% to 2.5% carbon. This level of carbon is necessary to combine with the carbide forming elements in the tool steels. These carbide-forming elements, when combined with the carbon, provide the necessary hardness and wear resistance.
