Low Temperature Phase Transition Behavior of Ca-Doped Lanthanum Chromites Fu Guifu1,Zhu Xinde1,Ao Qing1,Liu Weiming1,SUN Liangcheng2,Li Shengli1 (1.College of Materials Science and Engineering, Shandong University, Jinan 250061, China;2.Baotou Rare Earths Institute, Baotou 014010, China) Abstract:Phase transition of LaCrO3 and doped-LaCrO3 was studied by DSC, TG and XRD, and thermal expansion......
phase. But the stress in the experiment during hand hammering only cause brittle rupture from cleavage to oriented, this can not offer enough driving force and diffuse alleyway of atom..., but the result is contrary by hand hammering. So it is obtained that whether the equilibrium phase can be obtain or not by the stress at room temperature mainly depends on the feature of deformation mechanism......
