幫翻譯機械材料英文"20點"

White heart malleable cast iron is produced by decarburizing the white pig iron(C 2.8~3.2%,Si 06~0.8%) packed in the steel box white the ferric oxide powder at 850~900°C for 3~5 days and cooling room temperature during 2 days. As ferric oxide, magnetite or mill scale in the rice grain size is usually used, and hematite is usually used with the lime stone grain in order to soften its oxidation power. In the box the produced oxygen reacts with carbon of pig iron to CO or CO2 which gets out of surface. Carbon of the pig iron diffuses to the surface and such oxidation reaction goes to the inner side layer by layer. So the surface is decarburized perfectly, and becomes only the soft ferritic iron, and the inner part of the piece is rich in pearlite and results in bad forginability. The photograph shows the part rich in ferrite near surface and photograph 24.1 and 24.2 show the microstructure of surface layer and the micro structure which contain the ferrite pearlite structures of innter part of the piece.

    白色心臟展性的生鐵由decarburizing 生產白色豬iron(C 2.8~3.2%, Si 06~0.8%) 被包裝在鋼箱子白色氧化鐵粉末在850~900.C 為3~5 幾天和冷卻的室溫在2 天期間。作為氧化鐵, 磁鐵礦或磨房標度在米粒度通常被使用, 並且赤鐵礦通常被使用以石灰石頭五穀為了軟化它的氧化作用力量。在箱子被生產的氧氣起反應與生鐵碳對離開表面的CO 或二氧化碳。生鐵的碳散開對表面並且這樣的氧化作用反應去內在旁邊層數由層數。如此表面是完全decarburized, 和成為唯一軟的鐵素體鋼, 並且片斷的內在部份在pearlite 和結果上是富有的在壞forginability 。相片顯示零件富有在純鐵裡在表面和相片24.1 和24.2 附近顯示表層和微結構微結構哪些包含片斷的innter

    有些翻不出來= =趴謝ㄝ..
