Experiments were carried out with the purpose of shortening the reducingperiod in small basic electric furnace for carbon steels of various carbon content.In some of the experimental heats reducing period was shortened by 20 mi-nutes and the others were made according to the normal procedure of the works.For some of the low carbon steel heats,the amount of ferro-silicon powder wasincreased by 20% and added in advance.The results,obtained from heats of shorterreducing period,show that the deoxidation and desulphurization...

Experiments were carried out with the purpose of shortening the reducingperiod in small basic electric furnace for carbon steels of various carbon content.In some of the experimental heats reducing period was shortened by 20 mi-nutes and the others were made according to the normal procedure of the works.For some of the low carbon steel heats,the amount of ferro-silicon powder wasincreased by 20% and added in advance.The results,obtained from heats of shorterreducing period,show that the deoxidation and desulphurization appear to be ascomplete as that of a normal heat,the content of nitrogen and non-metallic in-clusions being much less.In addition,the results on mechanical properties showthat in the case of medium carbon steel,the impact value is higher,and in thecase of low carbon steel the percentage of elongation and the rate of reductionof area are also slightly superior although the yield strength becomes somewhatlower.Such a shortening of reducing period also results in a 7% increase ofthe rate of production.It is suggested that in electric steel smelting process theappropriate deoxidation procedure and the length of reducing period should varyin accordance with different carbon content of the steel.A relationship of[S]/[O]=1.2—2.2 at the end of reducing period was ob-served,and the possibility of further shortening of the reducing period in makingmedium and high carbon steel was also pointed out.

在装料量为8吨的小型电炉上进行了冶炼各种碳钢的缩短还原期的研究。还原期缩短到70分钟(低碳钢冶炼中还增加矽铁粉加入量和提早加入时间)的结果是:脱氧、脱硫符合要求,钢中非金属夹杂物和氮的含量显著减少,并提高炉子生产率约7%。从而指出了以电炉冶炼碳钢时还原期的时间和脱氧制度应按钢中碳含量的不同而有所区别。并指出中、高碳钢冶炼中还原期缩短到50分钟左右的可能性。此外还观察到还原期末[S]/[O]=1.2—2.2的关系。

The mechanism of age-hardening of magnesium-zinc alloy has been investigated by means of hardness measurement, tensile test, metallographic examination and X-ray analysis. It is shown that when the magnesium-5%zinc alloy is aged at 200℃ for not too long a period, a hexagonal transition phase β' is precipitated, which is rod-like, orientated perpendicularly to the basal plane of the magnesium matrix and coherent to it. The existence of such transition β' precipitates raises the yield strength of the alloy...

The mechanism of age-hardening of magnesium-zinc alloy has been investigated by means of hardness measurement, tensile test, metallographic examination and X-ray analysis. It is shown that when the magnesium-5%zinc alloy is aged at 200℃ for not too long a period, a hexagonal transition phase β' is precipitated, which is rod-like, orientated perpendicularly to the basal plane of the magnesium matrix and coherent to it. The existence of such transition β' precipitates raises the yield strength of the alloy but does not change appreciably its rate of strain hardening in tension test at 77°K. It is presumed that when this age-hardened alloy was plastically deformed, the gliding dislocations were unable to cut through the β' rods but piled-up against them. The coherent stress field accompanying the β' phase is the principal reason to account for the rise of yield strength of the alloy after aging. Additional external stress must be applied in order to overcome such coherent stress field and to force the constricted gliding dislocations to cross-slip into the prismatic planes of the matrix.

用硬度、拉伸、金相及X射线等方法研究了镁-锌合金的时效硬化机制.研究结果指出:镁-锌(5%)合金在200℃时效时,析出具有六角结构、垂直于镁基体的基面且和基体共格的杆状β′过渡相.其主要作用是提高合金的屈服强度,而对其应变硬化率却几乎沒有影响.当这种时效合金受到范性变形吋,由于位错不能切过β′相而塞积于β′相之前.存在于β′相周围的共格畸变应力場是合金在时效状态屈服强度提高的基本原因.必须提高外加应力才能迫使位错克服这种畸变应力場的作用而交滑移到柱面上去.

The yield strength of both ends of a hot-rolled 10Ti steel roll was found to
