均匀化热处理
The paper applied FEM to simulate the temperature field of the remained heat treatment after rolling of Φ 32mm ribbed bar, and found out the causes of forming non uniform temperature at the head and tail.
采用有限元法对Φ32mm大规格带肋钢筋轧后余热处理过程的温度场进行了模拟分析,并找出了头尾温度不均匀的原因。
The results showed that the PbTiO_3 nanocrystal structure is uniform tetragonal phase perovskite structure when heat-treatment is above 600 ℃, and the grain size is increased by increase of calcining temperature.
分析表明:焙烧温度高于600℃时可形成单一四方相钙钛矿结构的PbTiO3纳米粉体,并且随热处理温度的升高,晶粒度增加。
