A detailed procedure, which is essentially a modification of Baker and Briggs' method, is described here for the synthesis of α-phenyl-β-(3,5-diiodo-4-hydroxy-phenyl)-propionic acid (Priodax). Two derivatives of Priodax, one ,being new, were also prepared. The Priodax obtained exhibits low toxicity and produces good cholecystographic shadows. An attempt was made to employ hydriodic acid and red phosphorus for the simultaneous reduction and demethylation of p-methoxy-a-phenylcinnamic acid without success. How-...

This paper describes the nature of striated inclusions present in certain mildsteel plates,the origin of such inclusions is discussed.Microscopic examinations supplemented by X-ray diffraction studies show thatthe main constituents of the striated inclusions present in the steel plates appearto be the same as found in the attacked layer of fire-clay refractories which predo-minately consist of mullite(3Al_2O_3·2SiO_2)and cristobalite.Taking into accountthe metallurgical history of the plate and change in the...

This paper describes the nature of striated inclusions present in certain mildsteel plates,the origin of such inclusions is discussed.Microscopic examinations supplemented by X-ray diffraction studies show thatthe main constituents of the striated inclusions present in the steel plates appearto be the same as found in the attacked layer of fire-clay refractories which predo-minately consist of mullite(3Al_2O_3·2SiO_2)and cristobalite.Taking into accountthe metallurgical history of the plate and change in the chemical compositionof the refractories brought about during teeming,there is reason to believe thatstriated inclusions in steel may be originated from the refractories caused bythe attack of MnO or MnO·FeO present in the liquid steel.

本文叙述在某低碳钢板材夹层所观察到的非金属夹杂物的特征,并对夹层的来源进行了分析。金相检查结合X射线鉴定结果指出矽酸盐夹层与受钢液侵蚀过的粘土耐火材料的矿物组成大致相同,主要为莫来石(3Al_2O_3·2SiO_2)及方石英。根据钢的生产过程,夹杂物的特征及粘土耐火材料受钢液侵蚀后化学成分改变的情况,认为矽酸监夹层的来源可能与钢液中的MnO或MnO·FeO侵蚀粘土耐火材料有关。这种分析并得到了理论的解释。

The decomposition of δ-ferrite at 750°,850° and 950℃ in quenched 18/8/3/1Cr-Ni-Mo-Ti stainless steel specimens has been studied microscopically,thetransformation products being electrolytically extracted and identified by X-raydiffraction method.At early stages of decomposition accicular austenite forms along certaincrystallographic planes of δ-ferrite.As a result,the remaining ferrite becomesenriched in Cr,Mo and impoverished in C,Ni,Mn,and was found to transformsubsequently to sigma which begins after heating for 5-6 minutes at 850℃.Precipitation of titanium carbide first occurs in the ferrite grains,later itmakes appearance along the ferrite-austenite interphase boundaries and along thetwinning planes within the austenite grain.The precipitation of titanium carbideseems to have no appreciable effect on the sequence of decomposition of δ-ferrite.The impact value of the steel was found to decrease very markedly before thecommencement of the δ→σ transformation and it is considered that this mightbe associated with the titanium carbide precipitation.

应用金相法研究了18/8/3/1 Cr-Ni-Mo-Ti不锈钢经1300℃固溶处理后在950℃,850℃及750℃恒温分解初期金相组织的变化,并用电解分离及X射线衍射方法鉴定在不同恒温分解阶段δ-铁素体分解的产物。观察到由于提高了固溶处理温度,高温固定下来的铁素体极为不稳定,在分解为奥氏体的同时有TiC的沉淀出现。当δ→γ的转变,由于Cr,Mo等合金元素的偏聚不能继续进行时,才发现残留的δ-铁素体转变为σ-相。过去一般认为18/8型不锈钢在550—1000℃保温后,室温冲击靭性的降低是由于σ-相的沉淀所引起的,试验结果指出在σ-相出现之前,钢的冲击靭性已显著下降,这种现象可能与δ-铁素体分解初期TiC的沉淀有关。
