合金碳化物的英文

• alloy carbide

• 合金:    alloy
• 碳化物:    carbide
• 碳化物合金:    carbide alloy
• 低合金碳钢:    carbon low alloy steel
• 高合金碳钢:    carbon high-alloy steel; high-alloy carbon steels

例句与用法

1. The size of microalloyed carbides is very small and some is only 2 ~ 3nm . so microcrack extending can be restrained
   并且，由于微合金碳化物尺寸很小，可达2 3nm ，对于微裂纹扩展有一定的约束作用。
2. In the specimen of low carbon , ferrite with low hardness and a little pearlite is found ; and the specimen of high carbon is made up of pearlite and various alloyed - carbide
   组织观察表明，碳含量较低的试样中主要是硬度不高的铁素体以及少量的珠光体；而碳含量较高的试样中则主要是珠光体以及各种合金碳化物。
3. The boundary of ferrite has been clarified and fined by adding re into crsomo . the intergranular corrosion induced by solution chromium decreasing can be restrained for nb , v , ti combing carbon in the steel . the wear resistance of stainless steel can be increased for the precipitation of microalloyed carbides
   其中，稀土能够净化铁索体晶界，并起到变质剂的作用，细化铁素体晶粒，改善不锈钢的韧性；铌、钒、钛能够与钢中的碳结合，减少固溶铬的损失，从而避免晶间腐蚀，同时细小微合金碳化物的沉淀析出可提高不锈钢的耐磨性。
