退火是什么意思啊（退火是什么意思）

1、2) cold-rolling冷轧1.Systematically investigated and discussed texture formation mechanism of IF steel sheet hot-rolled in ferrite region and its transformation mechanism during cold-rolling/annealing by means of the microstructure observation and crystallographic orientation distribution function(ODF).通过金相观察和织构ODF分析,系统地研究了铁素体区热轧IF钢织构的形成机制及其在冷轧和退火过程中织构转变的特点和机理.结果表明:铁素体区热轧IF钢时,在交滑移机制的作用下,主要得到纤维状的形变组织和较强的α丝织构和较弱的γ丝织构,同时有少量的再结晶晶粒存在;冷轧过程中,在位错滑移、晶粒转动以及晶内剪切带的共同作用下,形成典型的纤维状组织,α丝织构和γ丝织构都明显得到加强;退火时,再结晶组织和织构的形成主要受很强的定向形核机制和弱的选择长大机制控制2.Evolution of texture and tissue in cold-rolling processes were investigated by using the electron backscatter diffraction technique based on the scanning electron microscope.包钢3 mm厚CSP热轧板经过热处理来适当调整组织和硬度后进行冷轧,压下量为81.7%.采用基于扫描电镜(SEM)上电子背散射衍射(EBSD)分析方法研究冷轧过程中织构的演变.结果表明,冷轧过程{110}滑移系首先开动,导致冷轧成品形成31.1%的{112}〈110〉织构和14.7%的{001} 〈110〉织构,由于反应应力的作用形成39.2%的{111}面织构3.Compounding experiments on Steel-Al and Steel-Cu by cold-rolling,i.进行了钢-铜、钢-铝冷轧复合实验,即表面处理+复合轧制+轧后热处理。
