This article discusses the issue of increasing the efficiency of alloying low-carbon steel during electroslag remelting with fluxes obtained on the basis of multicomponent mineral raw materials. The process of transition of an alloying element, from molten slag to metal, was investigated in various operating modes of the slag system, where the system itself experienced various degrees of hydrodynamic impact. A model is proposed and described, showing the uneven distribution of the alloying element in the metal melt. The composition and structure of the obtained alloys are investigated.

Hot Forging Process

The current development of steel industry has constraints on the availability of raw materials, so we have developed local raw materials that are lateritic steels as a high potential for alternative manufacturing of steel. This research was conducted to understand the characteristics of lateritic steel through hot forging process by the mechanical and microstructure behaviour. The research methodology was chained by variety of preheating temperature of 800; 1000; 1200 °C and forging force from 0 until 1000 kilonewton. In case of hot forging values was obtained the impact and hardness properties also microstructure that compared with as-cast steels. The results of impact strength increased by 81.83% at the temperature of 1200 °C and the hardness increased by 4.99% at 1000 °C, for the microstructure analysis was produced the ferrite and pearlite phases with the fine grains. The chemical composition of steel is classified in low carbon steel included in lateritic steel it contains low alloy 1.78 Ni and 0.553 Cr %wt.

The Magnetic Field

The austenite steel after rolling was radiated by the alternating magnetism, and the effects that alternating magnetic on the austenite transition was studied. The result shows that the alternating magnetism promotes the austenitic grain growth of low carbon steel. If the magnetic field intensity is increased, it could provide better performance of raw materials to cold rolling processing.

History shows the development of human thinking patterns that are more advanced in understanding, utilizing and further knowing the causes and results of the findings obtained. Humans find strong material, with complex phenomena and unknown compilation yet, but they have felt of great benefit. And with the development of knowledge, conventional and modern processes are carried out to achieve the goal. Namely with the methods carried out, managing the metal has a different impact than before, then the metals change physically and non-physically. This study aims to learn more about the relationship of metals treatment to hardness and the vibration that occurs in metal material that is disputed. This research uses experimental methods on materials with treatment and un-treatment to study the correlation, which is supported by the method of testing the hardness test and vibration test. The results show that increased strain on hardness and vibration patterns of metal have full or correlated. In this study, un-load raw materials was obtained an average hardness value of 52.28 HRB with an average vibration of 1.448 mm / s. While the specimen with tensile load obtained an average hardness of 52.34 HRB with an average vibration pattern of 1.7388 mm / s. These results show an increase in hardness of 0.115% and vibration of 20.028%, which is an increase in stretching effect. It can be concluded, however that increasing strain loads increase the hardness and vibration of low carbon steel equivalent ST-37.

Allotriomorphic Ferrite

A Fe-0.05C-2.94Mn-1.87Si steel is heat treated using a two-stage isothermal holding process to obtain allotriomorphic ferrite and bainite. Two kinds of allotriomorphic ferrite are obtained, one with only carbon partitioning and the other, alloying element partitioning. It is observed that the allotriomorphic ferrite stimulates the adjacent bainite to select the similar variant on the side where near K-S relationship is maintained between ferrite and prior austenite. The longer the border length of the allotriomorphic ferrite, the larger the stimulated bainite area. The statistical measurement shows that the alltriomorhpic ferrite with alloying element partitioning stimulates such bainite variant selection as well as that with only carbon partitioning.
