The decrease of temperature ramp rate during heat treatments of the internal tin process causes an increase of the critical current density at low and medium magnetic fields (4-16T). This paper investigates the metallurgical origin of this benefit by considering the effects of a change of heating...
In view of the fact that steel is supplied in a state after hot rolling, and the choice of a suitable heat treatment is left to the buyer steel were examined after conventional heat treatments. Steel was studied in state as delivered, after normalization, after quenching and after quenching ...
Results showed that the mechanicalproperties of NST 37-2 steel can be changed and improved by various heat treatments for aparticular application. It was also found that the annealed samples with mainly ferrite structuregave the lowest tensile strength and hardness value and highest ductility and ...
Metal processing into alloys is a cost-effective approach to improve material structural and mechanical qualities. Heat treatments provide a way to improve the characteristics of alloys before forging. As shape requirements become more complex, the necessity to design solutions that do not compromise ma...

Because no chemicals are involved, heat treatments represent a contribution to environmental protection, even though an energy input is necessary for wood production (Hill, 2006). High temperatures often reduce the mechanical properties of wood during treatment. Kamdem et al. (2002) indicated that ...
The isochronal heat treatment time was determined to be 1 h. The following combination of conductivity and tensile strength of the deformation-processed Cu-7Cr in situ composite with a cumulative cold deformation strain of eight after isochronal aging treatments for 1 h could be attained respectively...
Studies the influence of heat treatments on the damage evolution and strength of a SiC/Ti-15-3 metal matrix composite (MMC), a titanium alloy. Conduction of heat treatments for 24 hours on axial and transverse unidirectional specimens; Tests of the specimens under nonproportional loading paths; ...
Effects of heat treatments on room temperature mechanical properties and stress-rupture properties of Rene 80 have been investigated. The microstructures were analyzed by optical microscope and scanning electron microscope after each step of heat treatments. With the decrease of aging temperature, the ave...
Studies of post-spray heat treatments of HVOF-sprayed Ni-based alloy coatings have not been reported so far, to our knowledge. The goal of the present study was to examine the effects of post-spray heat treatment on the microstructure and properties of HVOF-sprayed Ni–Cr–W–Mo–B alloy ...
