A bainite is a microstrucutre of steel consisting of needle-like particles of cementite embedded in a ferrite matrix.
yes
The particles (molecules) in steel are closely packed - steel has a high density. In solids, we think of the bonds holding the particles together like little springs. The stiffer these are, the more efficiently the wave can travel, so speed of sound tends to increase the denser the medium.
yes
yes. everything is made of tiny particles.
Yes; all objects have moving particles, known as electrons.
That is because sound waves travel through particles, and solid particles are closer than liquid/gas particles, thus, logically sound wave will travel faster in steel than in a fluid. :)
That is because of density.Lead has a high density than steel.
gamma particles have high penetration power they can easily penetrate several feet of steel walls.
Yes, under the proper conditions of distribution of carbon in small particles throughout the volume of the steel.
In some cases yes. If the stainless steel was not passified (removing iron particles left on stainless steel by contact with tool steel dies) with nitric or sulfuric acid then yes.
these industries give out harmful particles of carbon and other particles these sometimes causes for acid rain etc
