小弟英語(yǔ)很不好，寫(xiě)的東西語(yǔ)病很多，而且用詞不當(dāng)，句子不通順，希望能幫我把下面一段話(huà)修改下，成為一段通順的話(huà) 謝謝 By means of optical microscope and scanning electron microscope,Ti elements has good effect on grain refinement in the low carbon cast steel, but the content of Ti elements is unfavorable and exorbitant,the Mg-deoxidizing products can't induced intra-granular ferrite,but the sample steel which joins Mg element can reduce the number of Al-oxide,in addition, Mn-Ti,Mn-Ti-Al,Mn-Mg-Ti-Al composite inclusions can be the core of induceing intra-granular ferrite, the nucleation effect of TiN is not obvious, the inclusion which contain high Al element content can not adsorpt MnS,so the effect of nucleation is not ideal, the individual MnS can not have the effect on grain refining. At the same time, it found that MnS plays a vital role on grain refinement,and the inclusions only can adsorpt MnS to format the complex inclusions ,which can be the core of the intra-granular ferrite. |

| Titanium works well in grain refinement of the low carbon cast steel via characterization of optical microscope and scanning electron microscope, except that the content of titanium is exorbitant and unfavorable. Mg-deoxided products can’t induce intra-granular ferrite, but the sample steel which joins Mg element can reduce the number of Al-oxide. In addition, composite inclusions of Mn-Ti, or Mn-Ti-Al or Mn-Mg-Ti-Al can be the core of inducing intra-granular ferrite. The nucleation effect of TiN is not obvious, the inclusion which contains high content in Al element can not absorb MnS, which results in unfavorable nucleation. MnS alone displays bad effect on grain refining. However, it’s found that MnS plays a vital role on grain refinement, and the inclusions only can absorb MnS to form the complex inclusions, which can be the core of the intra-granular ferrite. |

By being observed through Metallurgical Microscopeand scanning electron microscope, the low carbon cast steel were refined after addition of Ti elements while high ratio Ti was not suggested。Mg-deoxidizing products alone cannot induce intra-granular ferrite,however the number of Al-oxide significant decrease in the sample steel into which added Mg element 。In addition, Mn-Ti,Mn-Ti-Al,Mn-Mg-Ti-Al composite inclusions can be the core inducing intra-granular ferrite formation, the nucleation effect of the inclusion which contain high Al element leading low MnS absorption is not ideal as well as TiN n。MnS alone can not have the effect on grain refining. Meanwhile it was found that MnS plays a vital role on grain refinement,and only the inclusions adsorpt MnS could format the complex inclusions ,which can be the core of the intra-granular ferrite. 乖乖。。同學(xué)。，。一般用被動(dòng)語(yǔ)態(tài)比較好。注意基本的單詞格式拼寫(xiě)錯(cuò)誤。。。如果英語(yǔ)不是太好就寫(xiě)簡(jiǎn)單句，用句號(hào)結(jié)束就可以了。不用大段大段一個(gè)句號(hào)就沒(méi)有。 意思相同即可，沒(méi)必要每段都和中文格式、句式一致的。 希望有用。 |
