珠光鐵礦灰鑄鐵配件
灰鑄鐵是一種鑄鐵.碳作為鑄鐵作為石墨{.的含量{.灰色的嘴是灰色的.具有良好的鑄造，切割性能，良好的耐磨性，耐磨性.，用於製造架子，盒子，盒子，{4}}，{4} {4} . . .，{4} {. . .，{{4}應力濃度，因此灰色鑄鐵的強度，可塑性和韌性低於其他鑄鐵.的強度，韌性，但是它具有極好的振動阻尼，低凹口敏感性和高磨損抗性.
灰色鑄鐵具有高碳含量（2 . 7％〜4 . 0％），可以將其視為帶有石墨的碳鋼矩陣。根據不同灰色鑄鐵的基質組織，分為三類：鐵基質灰鑄鐵；珍珠鐵氧體基質灰色鑄鐵；珍珠基質灰色鑄鐵。
Pearl-ferrite gray cast iron is in the bead and ferrite mixed matrix, distributed with relatively thick graphite sheet, the strength and hardness of this cast iron is lower than the former, but still can meet the requirements of the general body, its casting, shock absorption are good, and easy to melt, is the most widely used gray cast iron.
灰色鑄鐵的不同微組織本質上是鑄鐵中的碳的不同形式.灰色鑄鐵中的碳由碳（Fe3c）組合（Fe3c）和石墨碳.組成，而當碳組合為0時，{5}} 8％，是灰色的鑄鐵；當組合碳小於0.8％時，它是鐵氧體灰鑄鐵。當所有碳都在石墨中時，它是灰色鑄鐵。
The mechanical properties of gray cast iron are related to the organization of the matrix and the morphology of graphite. The sheet graphite in gray cast iron seriously separates the matrix, which is easy to cause stress concentration at the graphite tip Angle, so that the tensile strength, plasticity and toughness of gray cast iron are far lower than that of steel, but the compressive strength is equal to that of steel, and it is also the cast iron with the worst mechanical performance在常用的鑄鐵.同時，矩陣組織還對灰色鑄鐵的機械特性有一定的影響基質的灰色鑄鐵石墨片比灰色鑄鐵略大，灰色鑄鐵不如灰鑄鐵.，因此，珠子光體矩陣的灰色鑄鐵在行業中更常用.
