true pearlite interlamellar spacing of 82b steel billet can be obtained according to the results of vertical lamellar.
根据珠光体片层垂直于观察截面的片层间距,可以得到该珠光体团的真实片层间距。
the lower finish cooling temperature, the shorter interlamellar spacing in pearlite colonies and the higher tensile strength and ductility are.
终冷温度越低,珠光体片间距越细,强度和塑性越好;
the pearlitic steel with fine interlamellar spacing possesses excellent mechanical properties, such as high strength, good resistance against wear, and high fatigue life, etc.
