Steel has remained the most crucial of all structural materials. However, the steel production processes have changed over the years. Currently, due to the tendency of eliminating high energy consuming technologies, in both the international and domestic steel industry, liquid steel is manufactured in two basic aggregates: oxygen-blown converters and electric arc furnaces 1 . The development of...

As one of the most exciting inspection and powerful analysis methods in modern materials metallographic examinations, the difference interference contrast (DIC) method has many advantages, including relatively low requirement for specimen preparation, obvious relief senses observed under microscope. Details such as fine structures or defects that are not or barely visible in incident-light brig...

An increasing number of industrial applications need superstrength steels. It is known that refined grains and nanoscale precipitates can increase strength. The hardest martensitic steel reported to date is C0.8 steel, whose nanohardness can reach 11.9 GPa through incremental interstitial solid solution strengthening. Here we report a nanograined (NG) steel dispersed with nanoscale precipitates...

Lăzăroiu, Spiru Haret University, Bucharest, Romania The theory that we shall seek to elaborate here puts considerable emphasis on technological features of China’s steel production, its emergence as the world’s most significant steel producer and main manufact...

At present, the scattered and closed steel logistics resource should be integrated. Reasonable benefit allocation mechanism is the prerequisite for steel logistics resources integration. Based on previous studies on steel logistics resource integration, this paper proposes an important problem in steel logistics resources integration: benefit distribution. First, this paper gives the classifica...

The corrosion of steel reinforcement in an aging highway infrastructure is a major problem currently facing the transportation engineering community, in particular bridge engineers. In the United States, maintenance and replacement costs are measured in billions of dollars. Further, the use of deicing salts has resulted in steady deterioration of bridge decks due to corrosion. These concerns ha...

This investigation compared four conventional vehicle armour materials for performance under blast loading. The parameters measured were resistance to deformation, mechanical toughness and metallurgical microstructure. It was found that two of these, the M steel and A steel, showed the least deformation and M steel showed better shock energy absorption. B steel had high toughness but showed sig...

In this paper we have studied the effect of magneto-static field onpropagation of thermal wave generated in metal by pulsed laser. In fact this interactiongenerate acoustic wave in different mechanisms. However, always the commonmechanism in the interactions of laser pulse and metal is the thermo-elastic wavegeneration. Applying the suitable magneto-static field on the s...
