The microstructures of a 0.2C-3.6Ni steel are studied after isothermal transformation over a temperature range of 600–400°C after different times up to 10 ks at each temperature. It was observed that the transformation at ...

The utilization of industrial solid waste for metal recovery requires high-temperature tools due to the presence of silica and alumina, which is reducible at high temperature. In a plasma arc furnace, transferred arc plasma ...

Interstitial-free steel workpieces are deformed by equal-channel angular pressing (ECAP) for equivalent strain εvm = 3 and εvm = 21 followed by flash annealing. Microstructures are analyzed by optical microscopy, scanning ...

Tuning deformation mechanisms is imperative to overcome the well-known strength-ductility paradigm. Twinning-induced plasticity (TWIP), transformation-induced plasticity (TRIP) and precipitate hardening have been investigated ...

Coherency strengthening plays a major role in precipitation strengthening. The governing mechanism is based on the interaction of dislocations with the elastic strain field induced by the lattice misfit of precipitates and ...

The cold crushing strength (CCS) of directly reduced iron (DRI) with its apparent density was correlated. Two different types of DRI were tested which included the iron ore pellets reduced in the bed of carbonaceous ...

The higher strength of directly reduced iron (DRI) in pellet form is useful in handling, storing and charging from height without breakage. The DRI pellets commonly exhibit 60 kg cold crushing strength. In this work the ...

In the present investigation an attempt has been made to determine the effect of firing temperature, firing time and ingredients/additives (CaO, MgO, SiO2, Al2O3) on the swelling behaviour of iron ore pellets. For this ...

Tensile behaviour of the near a titanium alloy, Ti-6Al-5Zr-0·5Mo- 0·25Si (LT26A), was investigated in (α + β) as well as β treated condition, over a wide range of temperature from RT to 823 K. It was observed that there ...

In the present investigation an attempt has been made to determine the effect of reduction rate on the swelling behaviour of iron ore pellets. For this purpose two Indian iron ore fines from Bailadila and Noamundi deposits ...
