Modeling and Simulation of Heat Transfer in Loaded Continuous Heat Treatment Furnace () 摘要:Continuous furnaces are widely used in the heat treatment of mass-produced parts. However, the heating... based on the calculated temperature distributions and curves, especially, the fastest heated and slowest-heated temperature-distance profiles. A case study is carried out for the heat treatment......
be strengthened by heat treatment [6–8]. However, the addition of Sr has a great effect on the solution treatment of Al–Si–Cu alloys [9, 10]. Generally, the solution temperature should be below... on the tensile properties of Al–Si–Cu–Mg alloys. The results show that the two-stage solution treatment produced better tensile properties than conventional heat treatment. SOKOLOWSKI et al [12] reported......
, nanoporous Cu with nano-scale pore size was synthesized by dealloying the bulk Mn-Cu precursor using free corrosion method in acid solution. The effects of the heat treatment of the precursors... disks. These disks were polished and freely corroded in HCl solution. In the heat treatment, the Mn-Cu bulk was heated for 95 h at 1 253 K in a vacuum quartz tube and quenched in water to room......
