, and the cooperation of the wedging action incured by the mass of corrosion products gathering at the grain boundaries and the applied stress drives the pre-cracks extending along the grain boundaries to the depth......
. Four times of cyclic heat treatment refines the grain size from 1.33 mm to 0.59 mm, nevertheless the lamellar spacing increases from 0.71 μm to 1.38 μm. Extending the holding time and increasing......
are not monotone decrease with the extending of cooling ending time, since the different microstructures induced by different cooling processes. θ″ phase precipitated in cooling processes......
and 513.8 MPa respectively. However, further extending the pre-ageing holding time reduces the mechanical properties of 2519A aluminium alloy. The mechanical properties of the alloy are associated......
and extending the length of heat recovery stage can obtain better effect of heat recovery. Key words: sintering; heat transfer; exergy; numerical simulation; optimization 在钢铁生产中,烧结工序中的余热资源由于具有分散,间歇等特点,并且受到工艺......
are mainly attributed to the formation of strong basal texture. The deformation transition from stage Ⅱ to stage Ⅲ roughly corresponds to the stop of {101(▁)2} twin extending. Key words: AZ31......
oxalate can be converted to tricalcium aluminate hydrate (TCA) and calcium carbonate in sodium aluminate solution and sodium carbonate solution, respectively. Elevating temperature, extending residence......
included in the harmonic wavelet transform is founded. Thirdly, by extending the harmonic wavelet transform, the concept of the adaptive harmonic window and its theoretical equation without......
the initial stage of partial remelting. With the heat preservation time further extending, the semi-solid particles will combine and grow up to reduce the surface energy of the system. Furthermore......
density and compressive strength satisfies the power function. Moreover, the compressive strength is improved by 53% once extending the deposition time from 3 h to 5 h at 36 A/m2. Key words: porous Cu......
