Objective: Post-cure heat treatment in direct composites may lead to an improvement on mechanical properties, as a consequence of an increase in degree of conversion (DC). The aim of this study was to evaluate DC and microhardness (KHN) of four direct composites photoactivated by two methods ...

Although it is possible to heat treat welds, the usualsteel heat treatmentcycle of austenitising, cooling and tempering is generally impracticable. Distortion would be difficult and expensive to avoid and the weld metal would need to match the parent steel in composition (particularly in carbon con...
Although stabilized RA did not deteriorate the ductility and plasticity of the inductive quenched and tempered specimens QT1 and QT3, a high amount of the soft FCC phase reduced the tensile strength and hardness of the heat-treated steel. Hence, the suggested interrupted quenching for specimen QT...
It is known that a number of parts that operate in liquid media, such as the propellers of motorboats and pleasure river vessels, as well as the rotors of household pumps and the radiators and pumps in the cooling system of motor vehicles are made, as a

Methods to solution treat high-pressure die castings for the development of properties have been developed (e.g. Refs. [11–17]). However, because die castings generally have thinner walls and are more intricate in their design than sand casting or PM casting, there is a tendency for die ...
To get high hardness on electroless nickel you will need to heat treat at 400 °C for 1 hour,. if you do not want any discoloration you must either use a vacuum or an inert gas atmosphere. Brian Terry Aerospace - Yeovil, Somerset, UK publicly reply to Brian Terry...
6. 870 掳F is the preferred treatment to achieve adequate hardness and conductivity readings but 920 掳F (493 掳C) may be used to improve tensile properties. 7. Solution heat treat temperatures as low as 870 掳F (466 掳C) may be used to control recrystallization and surface cracking ...
Since CO2 may be involved in the process of carbonate precipitation Hollerbach and Krauss [1987] have suggested the use of CO2 to treat water and process fluids. The hydrogen ions released by the interaction with water (Equations 14.8 – 14.10) are available to convert the CaCO3 to Ca(HCO3)...
