1417624 Heat-treating steel; quenching apparatus NIPPON KOKAN KK 15 March 1973 [15 March 1972] Headings C7A and C7N A steel containing in wt per cent is heated into the range Ac 3 -1000C, preferably by induction, and is then cooled at 0.8 to 2C per second until transformation to a ...
The objective of this work was to investigate the effect of heat treatment on swelling, hardness, and surface quality of four wood species, namely black locust (Robinia pseudoacacia L.), common alder (Alnus glutinosa L.), Western prickly juniper (Juniperus oxycedrus L.) and plum (Prunus domes...
The recrystallization induced during the heat treatment process was analyzed. The present study indicated strong deformation of the local structure of the active metal in all of the samples investigated due to the metal-support interaction and the effects of the small particle size. Electronic ...
For the heat treatment times of 200 hours and longer, the Cusub3/subSn IMC layers located near the Cu substrate were also observed. The experiments showed there is a link between the thickness of IMC layers and decrease of the shear strength of solder joints. In general, the joints made ...
The subject mainly studies the relation between heat treatment of 60Si 2CrVA Spring Steel and properties ,by adopting the quench in different heating times and performing tempering experiments under different temperatures .We could measure its HRC and mechanical properties accessments ,observe its micro...

Proper heat treatment of the wear components is a critical aspect to optimum wear life. Mechanical and physical properties of the wear components can be altered so much by heat treatment, that if done improperly, more harm than good could result. Therefore, heat treatment must be understood and...
This paper describes optimization of heat treatment process for the 20CrMnMo steel.A new heat treatment process was tested and the microstructure and mechanical properties of 20CrMnMo steel were studied.Repeated tests were performed to find the metastable quenching and tempering process for this steel.Th...
