Application of the Cored Wire Injection Process in Iron Nodularization-Inoculation Treatment;

The adoption of optimizing ingredient proportioning;adding alloying element molybdenum,copper;late inoculation;adding microelement bismuth and forced cooling technique of water-cooling combine air-cooling was able to improve nodular graphite numbers and distribution.

The target of this project is to develop a system to combine the inoculation with the filter and to be used for thin section iron castings.

Investigation and analysis about the gestation and procreation status of patients suffering with induced abortion;

Sensitivity of editors in charge of journals of science and technology is the result of the fostering and gestation.

In contemporary female literature,gestation is endowed with the new implication that women create a new ego while they create a new life.

It is found that incubation period obviously exists, and that there exist three stages in the process of absorbing hydrogen: slow absorption, rapid absorption and extremely slow absorption.

The results show that there obviously exists incubation period before NdFeB alloys begin to absorb hydrogen,and that the incubation period is related with temperature and hydrogen pressure.

This paper analyzes causes of the inoculated cast iron produced by sand mould which smelted in cupola,and reasons for chill defect leading to high-hardness;moreover,the corresponding countermeasures have been put forward to solve different problems.

Effect of cooling rate on the incubation period of time temperature transformation curve;

In this paper choosing the Mo-Al system,by the idea of plotting the solid state phases,the evolvement of the incubation period and species of primary phase of interfacial reaction products are introduced during Mo-Al solid-solid interfacial reactions from the related theory and experiment,respectively.

The bainite incubation period,during isothermally holding or aging in testing steels and β copper base alloys after solution treatment,is a process,in which,due to solute atoms diffusion and segregation at the crystal defects and at〈001〉crystal directions in the parent phase,distinct regions of solute enrichment and solute depletion are formed.

Determination of barium in steel-making inoculant by plasma atomic emission spectrometry;

By controlling the composition of molten iron and temperature, controlling amount of ferro-chromium, choosing appropriate orts and amount of inoculants and using Te-coating, the leakage rate could be reduced effectively.
