Sintering of Aly

Sintering of Aly

Sintering of Aly

(OP)
With sintering,,,, the metal is not melted as in casting
Its compressed then heated to below its melt point

Is this right ?

Thats the question

thanks  

RE: Sintering of Aly

Sintering is a simple process whereby bulk basalt or a particular mineral or set of minerals in powder form are heated to a high temperature less than the melting point, whereby the particles bond to each other, producing a porous (on a microscopic scale) material. The material usually shrinks significantly, and often the sintering process occurs in a die with a compaction pressure. The vacuum in space generally helps this process. The heat can come from either direct solar energy and/or microwave. Microwave heating allows quicker uniform heating.

RE: Sintering of Aly

Sintering is used for many materials, including metal alloys and ceramics.  Sintering is performed at a temperature less than the melting temperature.  The mechanism for sintering is diffusion - at high enough temperature, the atoms of a material are mobile and diffuse to minimize surface energy.
