Heat Treatment of Malleable Irons

December 14, 2011

Ferritic and pearlitic malleable irons are both produced by annealing white iron of controlled composition. Malleable irons have largely been replaced by ductile iron in many applications. This is due in part to the necessity of ... Read More...

Heat Treatment of High-Alloy White Irons

December 14, 2011

High-alloy cast irons are an important group of materials whose production should be considered separately from that of the ordinary types of cast irons. The producing foundries usually have the equipment needed to handle the hea... Read More...

Heat Treatment of High Alloy Graphitic Irons

December 14, 2011

High-alloy cast irons are an important group of materials whose production should be considered separately from that of the ordinary types of cast irons. In these cast iron alloys, alloy content is well above 4% and, consequently... Read More...

Heat treating of aluminum and aluminum alloys

December 14, 2011

Heat treating processes for aluminum are precision processes. They must be carried out in furnaces properly designed and built to provide the thermal conditions required, and adequately equipped with control instruments to insure... Read More...

Heat Treatable Aluminum Alloy

December 14, 2011

Heat treating in its broadest sense, refers to any of the heating and cooling operations are performed for the purpose of changing the mechanical properties, the metallurgical structure, or the residual stress state of a metal pr... Read More...

Heat Treatment Basic Knowledge of Metal Casting

November 16, 2011

Heat treatment is very meaningful for metal casting design engineers and mechanical engineers, and heat treatment is a very high value method used to improve the quality of metal materials. Heat treatment can change or influence ... Read More...

Aluminum Alloy Heat Treatment Temper Designations

November 3, 2011

The physical properties exhibited by aluminum alloys are significantly influenced by the treatment of the sample. A standardized system has been developed to designate these treatments. The aluminum alloy data sheets generally ha... Read More...

Spheroidization

November 1, 2011

Spheroidization is an annealing process used for high carbon steels (Carbon > 0.6%) that will be machined or cold formed subsequently. This is done by one of the following ways: 1. Heat the part to a temperature just below ... Read More...

Full annealing

November 1, 2011

Full annealing is the process of slowly raising the temperature about 50�C above the Austenitic temperature line A3 in the case of Hypoeutectoid steels (steels with < 0.77% Carbon) and 50�C into the Austenite-Cementite re... Read More...

Principles of Heat Treating of Steels

August 10, 2011

Steel is usually defined as an alloy of iron and carbon with the carbon content between a few hundreds of a percent up to about 2 wt%. Other alloying elements can amount in total to about 5 wt% in low-alloy steels and higher in m... Read More...

Iron and Interstitial Solid Solutions

August 8, 2011

The study of steels is important because steels represent  the most widely used metallic materials, primarily due to the fact that they can be manufactured relatively cheaply in large quantities to very precise specifications. T... Read More...

Stainless Steel and Nickel Heat Treating

July 22, 2011

The heat treating process involves controlled heating and cooling of solid metals and alloys in order to manipulate the final mechanical properties. Essentially, heat treating changes the molecular structure of the materials to m... Read More...

Nitriding

July 9, 2011

Certain steel alloys can absorb nitrogen with a resulting extremely hard surface layer. The process consists of maintaining the steel component at a carefullly controlled temperature of 490oC to 530oC under the action of nasce... Read More...
