Effects of Heat Treatments on Steels for Bearing Applications

Effects of Various Ageing Heat Treatments on Microstructural Features and Hardness of Piston Aluminum Alloy

Piston aluminum alloys have different intermetallic phases, such as Cu3Al, Mg2Si ,and AlNi phases. The morphology and the distribution of such phases have important roles on mechanical properties of the piston material. Therefore, in this research, various ageing heat treatments on the mentioned material were done and the microstructural feature and the hardness were studi...

Solidification Phenomena and Properties of Some Cast Tool Steels

The freezing process. microstructures and phase relationships in some experimental cast tool steels have been investigated and developed under the various solidification conditions. Experimental steels were based on AISI M2 and M10 grades high speed steels. Addition of carbide forming elements such as niobium and titanium with and without extra carbon were made to the molten bath of the base st...

Best practice in heat treatment of large dies made of hot work tool steels

Tool steels are a widely used material for construction of tools designated for shaping and forming of metal, plastic and other elements in mass production. These elements include extruding dies, pressure casting dies, moulds, punches and various other elements for plastic shaping of other materials preheated to temperatures in the range of 250-700 °C (Fig. 1). Since shape stability constitutes...

Fundamental Principles of Heat - Treating Steels

eat-treating is a process that is critical to the fabrication of steel fasteners. It is a necessary process in order to achieve the mechanical properties. Heat-treating is typically conduc t ed a f t e r t he fo rming processes and before any coating or finishing processes. Heat-treating may be done by the manufacturer or outsourced to a commercial shop. The equipment necessary to effect ively ...
