Reduction characteristics and kinetics of iron oxide by carbon in biomass

The characteristics and kinetics of iron oxide reduction by carbon in biomass composites were studied. Iron oxide can be reduced by biomass very rapidly, and the degree of metallisation and reduction increases with temperature. Iron oxide reduction by carbon in biomass can be divided into two stages: reduction by volatile carbon followed by reduction by non-volatile carbon. The reduction times of the two stages both decrease with increasing temperature. The first reduction is controlled by gas diffusion, whereas the second stage is dominated by carbon gasification.

TB6钛合金等温锻后热处理工艺研究

采用等温锻压机对TB6钛合金方棒进行等温锻造,锻造完成后对锻件进行水淬和空冷2种不同方式的冷却,再对水淬的锻件进行时效处理,空冷的锻件进行固溶+时效处理。研究了等温锻后热处理工艺对TB6钛合金组织和力学性能的影响。结果表明,等温锻后水淬,α相尺寸较小,等温锻后空冷,α相尺寸较大;水淬后β基体上无感生α相,空冷后β基体上有感生α相形成;水淬+时效后析出的次生α相比空冷再经固溶+时效后析出的次生α相更加混乱。TB6钛合金经等温锻后水淬+时效处理,其强度和塑性与等温锻后空冷至室温再进行固溶+时效的水平相当,且平面应变断裂韧度更高。

Thermo-Calc calculations and studies of the heating process of Fe83Si4B13 alloy

The microstructural changes of Fe_(83)Si_4B_(13) amorphous mother alloy during the heating process were investigated by Laser Scanning Confocal Microscopy( LSCM),and the phase transformation was determined by the Thermo-Calc calculations. The differences in the melting points measured by Differential Scanning Calorimetry( DSC)and LSCM,and those obtained by Thermo-Calc calculations were also discussed. It is found that the melting points measured by DSC and LSCM are relatively similar,whereas the onset and end of the melting temperatures calculated by Thermo-Calc software are higher than those measured by DSC and observed by LSCM.

Effect of Zn Vaporization on Wetting of Al-galvanized Steel in Cold Metal Transfer Process

The wetting of galvanized steel by molten Al alloys was studied in the cold metal transfer process by the sessile drop method using a high speed video camera.The wetting behavior can be divided into two typical cases,trending of non-wetting by using small wire feeding speed and wetting by using large wire feeding speed.The Leidenfrost effect is caused by the volatilization of Zn,which is responsible for the former case.The enhanced wettability of steel by Al and the weakening of the Leidenfrost effect are responsible for the latter case.Zn is the destabilizing factor for Al-steel joining that needs to be avoided by a reasonable design of process.     

钛合金等温锻后冷却方式对组织和力学性能的影响

本文通过等温锻压机对TB6钛合金进行等温锻造,锻造完成后锻坯采取水淬和空冷不同的冷却方式,冷却完成后水淬的锻坯进行时效处理,空冷的锻坯进行固溶时效处理。研究TB6钛合金等温锻后不同的固溶时效制度对钛合金组织和力学性能的影响。结果表明,TB6钛合金等温锻后水淬的α相尺寸小于等温锻后空冷的α相尺寸,水淬的钛合金β基体上无感生α相,空冷的钛合金β基体上有感生α相形成。水淬的钛合金经时效后析出的次生α相比空冷的钛合金经固溶时效后析出的次生α相更加混乱。TB6钛合金等温锻后水淬经时效的强度和塑性与等温锻后空冷经固溶时效的水平相当,但断裂韧度前者高于后者。
