APPLICATIONS OF FeC PHASE DIAGRAM
Quenching Considerations •Water is an effective quenching medium because of its high heat of vaporization and relatively high boiling point –The quenchant should be agitated due to the tendency of bubbles to form soft spots on the metal –A negative consequence is that it may oxidize the material •Brine is similar to water as a quenchant ...

Properties of Cement Physical Chemical
When water is added to cement, the reaction that takes place is called hydration. Hydration generates heat, which can affect the quality of the cement and also be beneficial in maintaining curing temperature during cold weather. On the other hand, when heat generation is high, especially in large structures, it may cause undesired stress.

Cement Industry in India Trade Perspectives
Cement, White Cement, Portland Blast Furnace Slag Cement and Specialised Cement. The basic difference lies in the percentage of clinker used. Ordinary Portland Cement (OPC): OPC, popularly known as grey cement, has 95 per cent clinker and 5 per cent gypsum and other materials. It accounts for 70 per cent of the total consumption.

Portland cement clinker
Portland cement clinker overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.

water vapor actually in the air compared to the total amount of water vapor that the air can hold. As the temperature of air increases, its capacity to hold water vapor increases. Dew point is the temperature at which water vapor from the air begins to condense and is affected by the relative humidity and temperature of the air.

42CrMo4
42CrMo4 is a steel for quenching and tempering, which has a good combination of strength and toughness in the quenched and tempered condition. After the oil quenching, the steel will be through hardened up to ø60 mm bar diameter. The microstructure of larger dimensions is not fully martensite. The steel is applicable to induction hardening.

The Hamon: What, Where, Why and How
· WATER VS. OIL QUENCH. Producing the hamon involves a process of coating the blade with clay and then quenching it in either oil or water. The water quench is more rapid and therefore potentially more astrophic should a crack or complete break occur. "I use clay and white crushed stone," House noted. "A paste of satanite also works well.
