In comparing the trends prevailing abroad in the field of heat treatment of steel and cast iron parts with the situation in the Soviet Union, it can be concluded that they are identical. Mass production plants widely use induction heating in automatic stands; muffleless carburizing furnaces with ...
Lower temperature heat treatments are only applied to dissimilar metal joints to ferritic steel or to cladding when the code being followed demands heat treatment for the ferritic steel HAZ. Choice of a suitable temperature is not well defined, as some loss of properties is expected at all temper...
Exhaust air treatment systems (EATS) are used in animal husbandry to reduce emissions. However, EATS are associated with high acquisition and operating costs. Therefore, a plant technology is being developed that integrates a recuperative heat exchanger
For the nickel-based superalloys, existing processing practice involves the use of either investment casting, powder metallurgy or else an extensive series of thermal–mechanical working operations on vacuum induction melted material [1], [2]. A subsequent heat treatment is then needed to optimise pr...
A comprehensive exposition of the structure of steels and the effects of different heat treatments, particularly in respect of tools. It includes solid fuel, gas and electric furnaces, case hardening, tempering and other practical information. Features accurate colour temperature charts. 我来说两句 短...

Heat treatment of CPM S30VForging: 2100F (1150C) Do not forge below 1750F (950C). Annealing: Heat to 1650F (900C), hold 2 hours, slow cool no faster than 25F (15C) per hour to 1100F (595C), then furnace cool or cool in still air to room temperature. Annealed Hardness: About...
Pigeonpea is an important legume crop that has potential resilience in the face of evolving climate scenarios. However, compared to other legumes, there has been limited research on abiotic stress tolerance in pigeonpea, particularly towards drought stress (DS) and heat stress (HS). To address ...
