In this contribution, spray quenching of specimen using twin-fluid, flat-spray nozzles is evaluated in order to integrate the heat treatment process within an automated production line of forging or forming components. The quenching strategies firstly aim at providing appropriate microstructures (...
Heat treatment and quenching process in the hopes that by controlling the cooling rate of the spring to be high and uniform hardness and plenty of hardened layer depth, while reducing distortion and prevent cracking. 翻译结果4复制译文编辑译文朗读译文返回顶部 In heat-treated hardened in the process...
ManuSam, ...N.Radhika, inJournal of Manufacturing Processes, 2021 5.2Quenching Quenching process follows solutionizing process in heat treatment cycle. This process inhibits the formation of precipitates during solutionizing. It was observed that at room temperature, quenching helped in retaining higher...
For many years, gas quenching has been the preferred process in the heat treatment of steels. During High Pressure Gas Quenching (HPGQ) previously austenitized respectively thermochemically treated parts are quenched in an inert gas flow in a pressure range between 1 bar and 20 bar with gas v...
Quenching And Tempering is a common heat treatment process for steel, usually used to improve the properties of steel. The main purpose of Quenching And Tempering is to achieve a balanced organizational structure of steel through appropriate heating and

There is no evidence for the use of this hardening process during the early Iron Age, so that it must have been either unknown then or not considered advantageous, in that quenching renders iron very brittle and has to be followed by tempering, or reheating at a lower temperature, to ...
Quenching and tempering furnace The heat treatment process of steel includes annealing, normalizing, quenching, tempering and surface heat treatment. The tempering includes quenching and tempering treatment and aging treatment. Tempering of steel: reheating of hardened steel to (350 C to 650 DEG C) ...
Due to the potential evaporation of the quenching liquid during boiling, the local fluid flow as well as the heat transfer are extremely dynamic processes. Therefore, a numerical simulation model has been developed for flow and heat transfer to analyze the entire cooling process in the jet ...
