Effect of Cooling Rate and Vanadium Content on the Microstructure and Hardness of Medium Carbon Forging SteelWeijun Hui1,Yongjian Zhang1,Chengwei Shao1,Silian Chen2,Xiaoli Zhao2,Han Dong21. School... of cooling rate on the microstructure and hardness of a kind of medium carbon steel microalloyed with two levels of V content(0.15%and 0.28%)after hot deformation by using single compression tests......
；维氏硬度 中图分类号:TH140.7 文献标志码:A Method for determining Vickers hardness of materials by Vickers instrumented indentation work ratio and martens hardness WANG Jia-liang, MA De-jun... hardness does not recognize during the traditional Vickers hardness testing. The instrumented indentation test were analyzed by employing dimensional theorem and finite element method, meanwhile......
Effects of Welding and rotational speeds on the Microstructure and Hardness of Friction Stir Welded Single-Phase BrassSajjad Emami,Tohid SaeidMaterials Engineering Faculty, Sahand University of Technology摘 要:This study focuses on the effects of rotational and welding speeds on the microstructure and hardness of joints in friction stir welded single......
temperature due to the normal growth of grains. The deformation resistance in normal direction of the plates is increased by the basal plane texture {0001}, leading to the highest hardness of RD-TD plane. Meanwhile, The deformation resistance in transversal direction of the plates is increased by the texture of <>, <> and other recrystallization textures, therefore, the hardness of ND-RD plane......

K445高温合金；熔体保温时间；显微组织；硬度 中图分类号:TG 132.32 文献标识码:A Effects of melt holding time on microstructure and hardness of similar-K445 superalloy ZHAO Yong-qin, FAN Zhi...) Abstract: The effects of melt holding time on the microstructure and hardness of similar-K445 superalloy were investigated. The results show that melt holding time has no effect on the sorts of phases......
