英文
pearlitic matrix-
The strength of extension of low carbon ductile cast iron can reach 750mpa in casting state, the impact ductility can reach 20j / cm2. the diameter of graphite nodule is 5 - 20 ( am, the base body is consisted of pearlite -
低碳球鐵在鑄態下的抗拉強度可達750mpa ，沖擊韌性可達20j cm ~ 2 ，其中石墨球直徑在5 20 m ，基體以珠光體為主，有少量的鐵素體與滲碳體。The microstructure of lamellae pearlite has evolved ultrafine cementite particles throughout the ferrite matrix uniformly after five passes. the ferrite matrix is homogeneous grains, average grain size is - 0. 3 m. 2
變形五道次后，片層狀的珠光體組織演變成了超細的滲碳體顆粒均勻分佈於鐵素體基體的組織，鐵素體基體為均勻的等軸晶，平均晶粒大小為0 . 3 m 。The main results are as the following : ( 1 ) the microstructure of lamellae pearlite has evolved ultrafine cementite particles throughout the ferrite matrix uniformly after four passes. the ferrite matrix is homogeneous grains, and average grain size is - 0. 3um
主要結果如下： （ 1 ） ecap變形四道次后，片層狀的珠光體組織演變為了超細的滲碳體顆粒均勻分佈於亞微晶鐵素體基體的組織。A microstructure - based damage constitutive model for pearlitic materials
基於微結構損傷的珠光體材料本構行為研究The results show that small cr addition in steel can decrease the lamellar spacing of pearlite, and markedly increase strength and hardness with almost the same ductility and toughness, and accordingly improve wear and shelling - resistance of wheel steel
實驗結果顯示，加入微量的鉻，可以細化珠光體的片層間距，在保持韌塑性基本不變的情況下，顯著增加材料的強度和硬度，從而提高車輪鋼的耐磨性和抗剝離性能。On the surface of annealed 45 steel, as the pearlite in it contains cementite phase and has high crystal boundary density, the nucleation and growth of deposits prefer to occur at the pearlite at the beginning during depositioa the coating exists in form of nano - polycrystal layers composed by gathering of nano - sized crystals
在退火態45鋼表面，由於珠光體組織中含有滲碳體相且具有比較高的晶界密度，因而在沉積初期鍍層優先在此處形核和生長；鍍層在基體表面是以納米尺度的晶粒聚集在一起形成的聚晶體形式存在的。分享友人
