  • 用极固与金相研究工业纯铁的轧制与再结晶织构和组织。热轧后的试样经过两种冷轧方法:(1)压下率为98.8%,与(2)压下率为64.5%,中间700℃熟炼;二次冷轧和压下率63.5%。试样在氢气中分别于(a)650°和(b)1000℃熟炼。第一类材料的轧制织构经测定为(100)011+(112)110+(111)112.试样在a与γ区域熟炼后的主要取向为(100)011和(111)112。第二类材料的轧制织构与第一类相似,惟偏离角度较大。表面与内部织构不同。第二类材料熟炼后的再结晶织构基本上相似,金相组织显出第二次再结晶现象。

     

    A study of the preferred orientations and microstructure of armco iron after cold reduction and recrystallization has been made.The treatments consisted of hot-rolling the material into strips and (1) a cold reduction of 98.8 percent or ( 2 ) two cycles of cold reduction of about 64 percent with an intermediate anneal. All these specimens for recrystallization were treated in hydrogen at 650° and 1000℃.The components after deformation for material (1) were found to be (100) 011 +(112) 110 + (111) 112 . The primary orientations of the specimens treated in a and γ regions were determined as (100) 011 and (111) 112 .The cold rolling textures of material ( 2 ) were found to be the same as those of (1), the deviation angle being larger. The surface texture was different from the texture possessed by inside of the sheet. The microstructure showed the phe-namena of secondary recrystallization for the samples treated at higher temperature.
