In studying the regularity of expansion of self-stressing cement (type M) stone andits pipes during hydration and hardening, the method that we mainly employ is the de-termination of the remained amount of gypsum by chemical analysis, while methods of X-ray diffraction, electron microscopy, differential thermal analysis and tests of mechanicalproperties are also employed. The amount of remained gypsum to be controlled has beensuggested. Results have shown that ettringate, CSH gel and hydrocalcium are main pro-ducts of hydrated self-stressing cement (type M) paste, and monosulfate calcium sulfoa-luminate hydrate is also one of the products when gypsum is nearly exhausted. Resultsobtained also indicate that during expansion of the self-stressing cement (type M) stone,ettringate is the only expansive phase. Under the condition of pipe manufacturing processwith self-stressing cement (type M) now in our country, lf the remained gypsum is cont-rolled within the range of 1.5~2.1%SO_3 after steam curing and before water curing, andbelow 0.60% SO_3 after water curing, the pipes produced would not be deteriorated byexpansion during the water curing period or at use.

以化学分析硅酸盐自应力水泥石及其压力管中剩余石膏含量为主,并配合性能试验及X射线、电子显微镜、差热分析等方法,探讨了硅酸盐自应力水泥及其压力管在水化、硬化过程中的膨胀规律;提出了剩余石膏的控制范围。硅酸盐自应力水泥的主要水化产物是钙矾石、水化硅酸钙凝胶、氢氧化钙。在石膏接近消耗完的情况下还形成了一硫酸盐型水化硫铝酸钙。在主要膨胀阶段,硅酸盐自应力水泥石的膨胀相是钙矾石。在我国目前硅酸盐自应力水泥压力管的制管工艺条件下,蒸养后下水前的剩余SO_3如控制在1.50~2.10%间,水养出水时的剩余SO_3如控制在0.60%以下,就可保证这种水泥的压力管在水养阶段和使用过程中不会发生胀坏现象。

The age-hardening processes of a Mg-5wt%Zn alloy have been studied bymeans of hardness measurement and X-ray diffraction analysis. On aging of thisalloy at 165℃, two hardness peaks with corresponding structural changes in thealloy were noticed. X-ray investigation of this alloy in quenched state revealedthat plate-like zinc clusters parallel to (0001) and {1010} planes of the magne-sium matrix were formed. At the initial stage of 165℃ aging, two-and three-dimensional metastable transition phase β'_1 particles and one-dimensional transitionphase β'_2 rods were precipitated out from the super-saturated solid solution. β'_1 existedonly for very short periods, while B'_2 still grew after aging for a total period of100h. when an equilibrium phase β began to precipitate out. During aging at190℃, only one hardness peak appeared, corresponding to the concurrent pre-cipitation of β'_2 and β phases. The structural parameters of β'_1 and β'_2 and theirorientational relationships with the matrix have en determined. The thermal stability of β'_2 was found to be rather high at 250℃, implyingthe probable applicability of the aged Mg-Zn alloys at higher temperatures.

利用硬度测量和X射线衍射分析,研究了Mg-5%Zn合金的时效硬化过程.指出合金在165℃时效过程中出现两个硬度峰,反映合金内发生了相应的结构变化. 对淬火合金的X射线研究表明,Mg基体中出现平行于(0001)和{1010}面的片状Zn原子富集区.在165℃时效初期,过饱和固溶体合金中桥出细微的二维及三维的亚稳定过渡相β′_1及一维杆状过渡相β′_2.β′_2存在时间很短,β′_2继续生核成长.时效100h后,稳定沉淀相β开始析出,并与β′_2共存.在190℃的时效过程中只出现一个硬度峰,相应于合金中同时出现β′_2及β析出相.测定了β′_1和β′_2过渡相的结构参数及其与母相的取向关系. β′_2的热稳定性相当高,能在250℃长时间存在,说明Mn-Zn系统的时效合金有可能在较高温度下使用.
