PrCl_3-NaCl-LiCl phase diagram has been constructed from the phase diagrams of its sub-binary systems and of six quasi-binary systems measured by DTA technique.It is found that this ternary system is composed of five liquidus surfaces,seven second crystallization lines,two peritectic points and one eutectie point.The temperatures and compositions of invariant points are as follows:P_1(416℃,30.3 mol% NaCl,44.2 mol% LiCl,25.5 mol% PrCl_3);P_2(409℃,25.0 mol% NaCl,50.0 mol% LiCl,25.0 mol% PrCl_3);E(404℃,20.0 mol% NaCl,55.4 mol% LiCl,24.6 mol% PrCl_3).

在实验室模拟CSP工艺的加热条件，对30CrMo钢进行试验，用金相法测量脱碳层厚度，用失重法对30CrMo钢的氧化层厚度进行估算，结合氧化烧损研究了加热温度和保温时间对30CrMo钢的实际脱碳层厚度的影响规律。结果表明，在试验气氛为（体积分数，%）CO216.5、O20.8、H2O13、N269.7，加热温度范围为1000～1150℃时，30CrMo钢的实际脱碳层厚度随着加热时间的增加而增加，低于1050℃时，脱碳层厚度随着温度升高而增加，高于1050℃时，脱碳层由于氧化加剧而减少，1050℃为脱碳敏感温度。

30MnSi钢筋断裂分析

李智丽

物理测试

对发生滞后断裂的30MnSi钢筋进行了检测分析，经检验其断裂的原因为钢筋在热处理加热时钢筋与加热线圈接触打火表面产生了异常的马氏体组织，由于该组织的内应力较大导致钢筋滞后断裂。

The nitride in 30CrNi steel and its composition along boundaries have been studied by means of scanning Auger microprobe.The nitride identified metallographically is Zr(C,N)which contains a small amount of Ti and O.The interface width between the Zr(C,N)and the matrix is about 1.6 μm.An Fe-rich shell is.found on the surface of Zr(C,N)which appeared on the fracture surface.The thickness of shell is 0.1-0.8μm.The Fe concentration of its outmost layer is 3-18 at.-% and decreases exponentially along the depth direction.
