Heat Treatment of Steels & Metals - Bright Hub Engineering

Heat treatment of steels is the heating and cooling of metals to change their physical and mechanical properties, without letting it change its shape. Heat treatment could be said to be a method for strengthening materials but could also be used to alter some mechanical properties such as improving formability, machining, etc.

Iron - Wikipedia

The melting and boiling points of iron, along with its enthalpy of atomization, are lower than those of the earlier 3d elements from scandium to chromium, showing the lessened contribution of the 3d electrons to metallic bonding as they are attracted more and more into the inert core by the nucleus; however, they are higher than the values for

Graphite (C) - Classifications, Properties & Applications

After graphite is mined, it usually requires a considerable amount of mineral processing like froth flotation to concentrate the graphite. Natural graphite is an excellent conductor of heat and electricity, stable over a broad range of temperatures, and a highly refractory material with a high melting point of 3650 °C.

Sintering - Wikipedia

Sintering is effective when the process reduces porosity and enhances properties such as strength, electrical conductivity, translucency and thermal conductivity; yet, in other cases, it may be useful to increase its strength but keep its gas absorbency constant as in filters or catalysts.During the firing process, atomic diffusion drives powder surface elimination in different stages

PDF Chapter Outline: Phase Diagrams

The melting point of the eutectic alloy is lower than that of the components (eutectic = easy to melt in Greek). At most two phases can be in equilibrium within a phase field. Three phases (L, α, β) may be in equilibrium only at a few points along the eutectic isotherm. Single-phase regions are separated by 2-phase regions.

Large porosity, in particular, may act to cause cracking during subsequent processing. Hard refractory inclusions (i.e., ceramic particles from melting crucibles or investment molds, or "dirt" from the workshop that falls into the melt) resist deformation during working and act as crack initiators in the gold alloy.
